Your Massey Ferguson 1735M compact utility tractor requires precise maintenance following specific specifications to deliver reliable performance through thousands of hours of operation. Understanding fluid capacities, filter specifications, torque values, and service intervals ensures your tractor receives proper care preventing expensive repairs. This comprehensive guide covers every maintenance specification for the Massey Ferguson 1735M with part numbers, capacities, procedures, and technical details.
The 1735M is Massey Ferguson’s 34.5-horsepower compact tractor, part of the 1700M series built for small farms, estates, hobby farms, and commercial landscaping operations. These tractors feature hydrostatic transmission, Category 1 three-point hitch, and available loader and backhoe compatibility. Proper maintenance keeps these versatile machines working reliably.
Complete Fluid Capacity Specifications
Understanding exact fluid capacities prevents overfilling and underfilling—both of which cause problems. These capacities are for the MF 1735M standard configuration; verify your specific model year and configuration in your operator’s manual.
Engine Oil Capacity
Capacity with filter change: 3.7 quarts (3.5 liters)
Capacity without filter change: 3.4 quarts (3.2 liters)
Oil specification: API CJ-4 or later diesel engine oil
Viscosity: SAE 15W-40 for temperatures -10°F to 100°F+
Alternative viscosity: SAE 10W-30 for cold climates below -10°F
Alternative viscosity: SAE 20W-50 for sustained operation above 100°F
The Massey Ferguson 1735M uses an Iseki 3-cylinder diesel engine requiring quality diesel-rated oil. Never use automotive motor oil—diesel engines need specific additives for combustion byproducts, soot handling, and high-temperature protection.
Synthetic oil meeting the same specifications is acceptable and provides better extreme-temperature protection, but doesn’t eliminate the need for regular oil changes. Follow the same 200-hour interval regardless of conventional or synthetic oil.
Fuel Tank Capacity
Main fuel tank: 7.4 gallons (28 liters)
Use ultra-low sulfur diesel (ULSD) #2 for temperatures above 10°F. In cold climates, use winterized diesel blends or #1 diesel for temperatures below 10°F to prevent fuel gelling.
Never let the fuel level drop below 1/4 tank. Running low allows sediment from the tank bottom to enter the fuel system and increases condensation leading to water contamination.
Coolant System Capacity
Total system capacity: 2.4 gallons (9 liters) including radiator, engine block, hoses, and overflow reservoir
Coolant specification: Ethylene glycol-based coolant meeting ASTM D3306 standards
Concentration: 50% coolant, 50% distilled water for -34°F freeze protection
Alternative concentration: 60% coolant, 40% water for -62°F freeze protection (extreme cold climates)
Use distilled water only—never tap water. Minerals in tap water cause corrosion, scaling, and reduced heat transfer. Pre-mixed 50/50 coolant is convenient and eliminates mixing errors.
Extended-life coolants (OAT or HOAT formulations) are acceptable if they meet ASTM D3306 specifications. These provide 5-year service life versus 2-3 years for conventional coolant.
Hydrostatic Transmission/Hydraulic System Capacity
Total system capacity: 6.6 gallons (25 liters) including transmission, hydraulic pump, filter, lines, and cylinders
Fluid specification: Multi-purpose tractor hydraulic fluid meeting ISO VG 46 viscosity
Massey Ferguson specification: MF M1143 or equivalent
Alternative fluids: Universal Tractor Transmission Fluid (UTF) specifically stating compatibility with hydrostatic transmissions
The 1735M uses a single integrated system for the hydrostatic transmission, three-point hitch, power steering, and remote hydraulics. All share a common reservoir and fluid. This simplifies service but requires using the correct multi-purpose fluid that handles all applications.
Don’t use straight hydraulic oil, ATF, or motor oil. Hydrostatic transmissions require specific friction characteristics and viscosity that generic fluids don’t provide. Wrong fluid causes sluggish transmission response, whining noise, overheating, and premature failure.
Front Axle Differential Capacity (4WD Models)
Capacity: 0.85 gallons (3.2 liters)
Fluid specification: SAE 80W-90 API GL-5 gear oil
Alternative: Multi-purpose tractor hydraulic fluid (same as transmission)
Some operators prefer using the same multi-purpose hydraulic fluid in the front axle as the transmission for year-round convenience. It flows better in cold weather than 80W-90 gear oil. Either is acceptable.
Rear Axle/Final Drive Capacity
Combined capacity (both sides): Shared with hydrostatic transmission system
The rear axle and final drives on the 1735M share fluid with the hydrostatic transmission and hydraulics. When you service the transmission/hydraulic fluid, you’re simultaneously servicing the rear axle and final drives.
Power Steering System
Capacity: Shared with hydraulic system
The power steering pump draws from the common hydraulic reservoir. There’s no separate power steering fluid—it uses the same multi-purpose tractor hydraulic fluid as the transmission and three-point hitch.
Massey Ferguson 1735M Filter Specifications and Part Numbers
Using correct filters ensures proper filtration protecting expensive components. These part numbers are for genuine Massey Ferguson filters; quality aftermarket alternatives are available at lower cost.
Engine Oil Filter
Part number: 4370336M1
Type: Spin-on cartridge
Thread size: M20 x 1.5
Gasket diameter: 62mm
Height: Approximately 76mm
Service interval: Every 200 hours or annually, whichever comes first
First service: 50 hours (break-in oil change)
The oil filter mounts on the right side of the engine near the oil pan. It’s a standard spin-on design easily removed with a strap wrench or filter pliers.
Quality aftermarket filters from reputable manufacturers work fine if they match these specifications. Verify the filter lists the Massey Ferguson 1735M in the application guide and has the correct thread pitch and gasket diameter.
Fuel Filter
Primary filter/water separator: Part number 4283862M1
Type: Spin-on with integral water separator bowl
Service interval: 200 hours or annually
The fuel filter is a combination filter and water separator that removes both particles and water from diesel fuel. It mounts under the hood on the left side of the engine.
This is a critical component—diesel injection systems operate at extremely high pressure and tight tolerances. Contaminated fuel destroys injection pumps and injectors costing thousands in repairs. Always use quality filters and drain water from the separator bowl regularly.
Air Filter Elements
Outer element: Part number 4283561M1
Inner safety element: Part number 4283560M1
Type: Dual-element dry filter
Outer element service interval: Clean/inspect every 100 hours; replace every 200-400 hours or when damaged
Inner element service interval: Replace every 400-600 hours or if outer element was damaged
The 1735M uses a dual-element air filter system. The outer element catches the majority of contaminants and requires regular cleaning or replacement. The inner safety element provides backup protection and stays in place except during replacement intervals.
Never operate without the inner element installed—it’s your last defense against engine contamination if the outer element fails or is improperly installed.
Hydraulic/Transmission Filter
Part number: 4370435M1
Type: Spin-on cartridge
Service interval: 400 hours or annually
Location: Right side of transmission case beneath operator platform
The hydraulic filter protects pumps, valves, cylinders, and hydrostatic transmission components from abrasive wear. Change it at 400-hour intervals along with the hydraulic fluid, or annually if you don’t accumulate 400 hours per year.
If hydraulic fluid analysis shows elevated particle counts or metal contamination, change the filter early regardless of hours.
Transmission Suction Screen
Part number: Check your parts manual for specific number
Type: Metal mesh screen in hydraulic reservoir
Service interval: Clean at every hydraulic fluid change (400 hours)
The suction screen pre-filters fluid before it enters the hydraulic pump. It’s often overlooked but critical—a clogged screen starves the pump causing cavitation noise and damage.
Access it by removing the hydraulic reservoir cover. Pull the screen straight up, clean it thoroughly in solvent, blow dry with compressed air, and reinstall ensuring proper seating.

Lubrication Point Specifications
The 1735M has multiple grease fittings requiring 100-hour service. Use multi-purpose lithium-based or polyurea-based grease rated NLGI Grade 2.
Front Axle Lubrication Points (4WD Models)
Front axle pivot pin – 1 fitting
Shots of grease: Pump until purge from seals (approximately 3-5 shots)
Steering cylinder pins – 2-4 fittings depending on configuration
Shots of grease: Pump until purge (2-3 shots per fitting)
Front wheel bearings – 2 fittings (one per hub)
Shots of grease: 3-5 shots per hub
Front drive shaft U-joints – 2 fittings
Shots of grease: Pump until purge from bearing caps
Front axle steering knuckles – 4-6 fittings (2-3 per side)
Shots of grease: Pump until purge from all seals—these are critical wear points
Three-Point Hitch Lubrication Points
Lift arm ball joints – 2 fittings
Shots of grease: Pump until purge
Check chain anchors – 2 fittings (if equipped)
Shots of grease: 2-3 shots per fitting
Leveling mechanism – 1-2 fittings
Shots of grease: 2-3 shots
Stabilizer mounts – 2 fittings (if adjustable stabilizers)
Shots of grease: 2-3 shots per fitting
Loader Lubrication Points (If Equipped)
Exact number varies by loader model, but typical points include:
- Loader mounting pins: 2-4 fittings
- Boom pivot points: 2 fittings
- Bucket pivot pin: 1 fitting
- Bucket cylinder pins: 2 fittings
- Boom cylinder pins: 2 fittings
Pump grease until you see old grease purge from seals at all points.
PTO Shaft
Apply grease to the PTO output shaft splines to prevent wear and allow implement driveshafts to slide freely during operation. Wipe off excess to prevent dirt accumulation.
Torque Specifications
Proper torque prevents both loose fasteners and damaged threads. Use a calibrated torque wrench for critical fasteners.
Drain Plugs
Engine oil drain plug: 25-30 ft-lbs (34-41 Nm)
Hydraulic/transmission drain plug: 30-35 ft-lbs (41-47 Nm)
Front axle drain plug: 20-25 ft-lbs (27-34 Nm)
Over-torquing drain plugs strips threads in aluminum housings. Under-torquing causes leaks. Use new crush washers when available.
Oil Filters
Engine oil filter: Hand-tighten gasket to block, then 3/4 turn additional
Hydraulic filter: Hand-tighten gasket to mount, then 3/4 turn additional
Fuel filter: Hand-tighten gasket to head, then 1/2 turn additional
Never use filter wrenches to tighten spin-on filters—gasket compression seals them, not thread torque. Over-tightening crushes gaskets causing leaks and makes future removal difficult.
Wheel Lug Nuts/Bolts
Front wheels (4WD): 60-65 ft-lbs (81-88 Nm)
Rear wheels: 95-105 ft-lbs (129-142 Nm)
Torque wheel fasteners in a star pattern, not sequentially around the wheel. Recheck torque after the first hour of operation following wheel removal.
Loader Mounting Bolts (If Equipped)
- Loader frame attachment bolts: 80-90 ft-lbs (108-122 Nm)
- Loader pin retaining bolts: 40-45 ft-lbs (54-61 Nm)
Check loader mounting bolt torque every 50 hours initially, then every 100 hours once stable.
Belt Specifications and Adjustment
The 1735M uses V-belts to drive the alternator and cooling fan from the engine crankshaft.
Alternator/Fan Belt
Part number: Consult parts manual for specific number (varies by engine configuration)
Belt type: Wrapped V-belt
Proper tension: 1/2 inch (13mm) deflection under moderate thumb pressure at longest span
Check belt tension every 200 hours. A loose belt slips, squeals, causes poor charging, and overheating. An over-tight belt stresses bearings causing premature failure.
To adjust belt tension, loosen the alternator mounting bolts and pivot bolt. Move the alternator away from the engine to increase tension. Tighten bolts and recheck deflection.
Replace belts showing:
- Cracks or fraying on edges
- Glazed or shiny contact surfaces
- Missing chunks or pieces
- Significant wear on inner surface
Don’t wait for belt failure—it leaves you stranded. Replace questionable belts during scheduled maintenance.
Tire Specifications and Pressure
Proper tire pressure ensures optimal traction, tire life, stability, and ride quality.
Front Tires (4WD Models)
Common size: 27 x 8.5-15 or similar
Recommended pressure: 20-24 PSI for normal use
Maximum pressure: See tire sidewall (typically 32 PSI)
Minimum pressure: 18 PSI
Lower pressure (18-20 PSI) increases traction in soft or muddy conditions but accelerates tire wear on hard surfaces. Higher pressure (22-24 PSI) is better for road travel and hard surfaces.
Rear Tires
- Common size: 15-19.5 or R4 industrial pattern
- Recommended pressure: 14-18 PSI for agricultural us
- Recommended pressure: 20-24 PSI for industrial tires on hard surfaces
- Recommended pressure: 24-28 PSI for turf tires
Agricultural tires run lower pressure for better traction and flotation. Industrial and turf tires require higher pressure for their construction and intended use.
Always check tire pressure when tires are cold—pressure increases 2-4 PSI as tires warm during operation. Check pressure weekly or every 50 hours.
Battery Specifications
Type: 12-volt lead-acid automotive/tractor battery
Minimum cold cranking amps (CCA): 350-400 CCA
Reserve capacity: 60+ minutes recommended
Group size: Typically Group U1 or similar compact tractor size
Higher CCA ratings provide easier starting in cold weather. Reserve capacity determines how long the battery powers accessories with a failed alternator.
Battery Maintenance
Check battery terminals monthly for corrosion and tight connections. Clean corroded terminals with a wire brush and baking soda solution.
If your battery is conventional (serviceable), check electrolyte level in each cell and add distilled water to cover the plates. Maintenance-free batteries don’t require water addition.
Test the charging system annually—with the engine running at 1500-2000 RPM, voltage at the battery terminals should be 13.8-14.5 volts indicating proper charging.
Hydraulic System Specifications
Operating Pressure
Maximum system pressure: 2,400-2,500 PSI (165-172 bar)
Relief valve setting: 2,400 PSI ± 100 PSI
Don’t adjust relief valve pressure unless you have proper test equipment and training. Excessive pressure damages seals, hoses, and cylinders.
Flow Rate
Hydraulic pump output: Approximately 6.3 GPM (24 liters/minute) at rated engine RPM
Reduced flow indicates pump wear or restricted suction screen. If loader or three-point hitch operate slowly compared to new, test hydraulic pressure and flow.
Remote Hydraulic Valves (If Equipped)
Maximum flow per remote: Depends on valve configuration
Pressure: Same as main system (2,400 PSI)
When operating implements via rear remotes, use appropriately-sized hydraulic hoses. Under-sized hoses restrict flow and overheat. Over-sized hoses are unnecessarily expensive but don’t hurt performance.
Three-Point Hitch Specifications
Category: Category 1
- Lift capacity at 24 inches behind lift points: Approximately 1,800 lbs (816 kg)
- Lift capacity at maximum lift point distance: Approximately 1,200 lbs (544 kg)
Lift capacity decreases as distance behind the lift points increases due to leverage. Heavy implements mounted far behind the lift points may exceed the hitch’s capacity.
Lower link adjustment range: Multiple pin positions for different implement widths
Top link length adjustment: 21-26 inches (adjustable turnbuckle)
Stabilizer position: Adjustable from free-floating to rigid
Engine Specifications Summary
Engine model: Iseki 3-cylinder indirect injection diesel
Displacement: 1.5 liters (91 cubic inches)
Bore: 78mm (3.07 inches)
Stroke: 82mm (3.23 inches)
Rated power: 34.5 HP (25.7 kW) at 2,800 RPM
Maximum torque: Approximately 70 ft-lbs (95 Nm)
Compression ratio: 21.5:1 (typical for indirect injection diesel)
Aspiration: Naturally aspirated (no turbocharger)
Cooling: Liquid-cooled with pressurized radiator system
Valve clearance (engine cold):
- Intake: 0.008-0.010 inches (0.20-0.25mm)
- Exhaust: 0.010-0.012 inches (0.25-0.30mm)
Valve clearance adjustment requires removing the valve cover and is typically performed every 600-800 hours or when valve noise develops. This is generally dealer service requiring proper feeler gauges and adjustment tools.
Transmission Specifications
Type: Hydrostatic transmission with mechanical range selection
Ranges: Typically 2-range (high/low) with infinite speed variation in each range
Forward speed range: 0-12 MPH (depending on range and configuration)
Reverse speed range: 0-8 MPH
Control: Foot pedal for forward/reverse and speed; hand lever for range selection
The hydrostatic transmission provides infinite speed variation without clutching or shifting within each range. Use low range for heavy work, loader operation, and maximum power. Use high range for transport and lighter work requiring more speed.

Massey Ferguson 1735M Common Specification-Related Issues
Wrong hydraulic fluid causing sluggish response – The hydrostatic transmission requires multi-purpose UTF fluid, not straight hydraulic oil. Using the wrong fluid causes slow response, whining, and overheating. Drain and refill with correct specification fluid.
Overheating from incorrect coolant concentration – Too much water (weak concentration) reduces boiling point and corrosion protection. Too much coolant (strong concentration) reduces heat transfer. Test concentration annually and maintain proper 50/50 ratio.
Oil consumption from wrong viscosity – Using 10W-30 in hot weather or 20W-50 in cold weather causes excessive consumption or poor lubrication. Match oil viscosity to operating temperature range.
Air filter restriction from extended intervals – Dusty conditions clog air filters quickly. Don’t rely solely on hour intervals—check the restriction indicator and service when needed.
Quality replacement filters meeting these specifications are available from FridayParts at competitive prices without compromising protection.
Frequently Asked Questions
What happens if I use 10W-30 instead of 15W-40 engine oil in Massey Ferguson 1735M?
10W-30 is acceptable in cold climates (below -10°F) but provides less protection in hot weather than 15W-40. If you operate in moderate to hot climates, use 15W-40 as specified. The thicker oil at operating temperature provides better protection for the high-compression diesel engine.
Can I use generic hydraulic oil instead of multi-purpose tractor fluid?
No. The hydrostatic transmission requires specific friction characteristics and viscosity that straight hydraulic oil doesn’t provide. Use only fluids meeting ISO VG 46 UTF specifications and stating compatibility with hydrostatic transmissions. Wrong fluid causes transmission problems.
How do I know if my coolant concentration is correct?
Use a refractometer or coolant hydrometer to test concentration. These inexpensive tools measure freeze protection accurately. Proper 50/50 mixture protects to -34°F. Don’t guess—test annually and adjust if needed.
Why does my specification manual list different capacities than this guide?
Minor variations exist between model years, configurations (2WD vs 4WD), and markets (North America vs Europe). Always verify specifications in your specific tractor’s operator manual. These are general specifications for standard 1735M configurations.
Should I use synthetic fluids instead of conventional fluids in Massey Ferguson 1735M?
Synthetic engine oil and hydraulic fluid provide better extreme-temperature protection and longer life but cost significantly more. They’re beneficial if you operate in extreme cold or heat, but conventional fluids meeting specifications work fine for normal conditions. Synthetic doesn’t eliminate regular maintenance—you still change at the same intervals.
