The Massey Ferguson 35 and 65 are two of the best-known early Massey Ferguson tractors and remain exceptionally popular restoration and working machines.
This guide covers the family in general. Engines, transmissions, hydraulics, PTO systems, axles, brakes, electrical equipment and production details can vary by model, market and serial range. Use the exact workshop manual for all pressure, torque, timing, clearance and adjustment data.
1. Why the MF35 and MF65 Remain Popular
Both tractors are simple, compact and highly repairable. They remain common on small farms, estates, classic-tractor collections and restoration projects.
- Simple mechanical diesel systems
- Ferguson three-point linkage
- Widely available service parts
- Strong restoration following
2. Identification Before Ordering Parts
Record the tractor model, serial number, engine type and transmission/PTO arrangement. Do not rely on bonnet decals alone because many tractors have been repainted or rebuilt.
3. Engine Families
MF35 and MF65 tractors were produced with different engine options depending on model and market. Diesel engines are especially common, but petrol and other variants exist.
Confirm the exact engine before ordering pistons, liners, bearings, injectors or gaskets.
4. Cold Starting and Fuel System
Hard starting should be approached in order:
- Battery and cranking speed
- Cold-start system
- Fuel supply and filters
- Air in the system
- Compression
- Injection timing and injector condition
5. Engine Smoke
- White smoke: poor cold combustion, timing, injector or compression issues.
- Black smoke: excess fuel, air restriction or heavy load.
- Blue smoke: oil entering the combustion chamber.
6. Cooling System
Inspect radiator, fan belt, thermostat, water pump, hoses and coolant. Old radiators can be internally restricted even if the fins look clean.
7. Clutch and Dual-Stage Arrangements
Depending on specification, the clutch may control both tractor drive and PTO through a two-stage arrangement.
Common faults include slipping, dragging, stuck clutch plates after storage and incorrect pedal adjustment.
8. Gearbox and Transmission
Check for gear noise, jumping out of gear, selector wear, bearing rumble and water contamination. Confirm whether the tractor has standard gearing or additional ratio options before repair.
9. Multi-Power Where Fitted
Some Massey Ferguson tractors were fitted with Multi-Power. It is not a conventional mechanical high/low box and should be diagnosed with the correct hydraulic and transmission procedure.
On Multi-Power tractors, use the correct range for downhill operation. Do not assume engine braking is available in every position.
10. PTO System
Identify whether the tractor uses transmission-driven, live or independent-style PTO arrangements. PTO complaints can result from clutch adjustment, linkage faults, internal clutch wear or selector problems.
11. Ferguson Hydraulic Linkage
The three-point linkage is central to both tractors. Check position control, draft response, lift speed, holding ability and lowering control.
12. Linkage Will Not Raise
Check oil level, pump drive, filter/strainer where fitted, control linkage, relief valve, pump condition and internal leakage before dismantling.
13. Linkage Drifts Down
Possible causes include lift-cylinder leakage, piston/ring wear, control-valve leakage or check-valve leakage.
14. Steering and Front Axle
Inspect steering box, drag links, track rods, kingpins, wheel bearings and centre pivot. Loader tractors often show increased front-axle wear.
15. Brakes
Check pedal travel, balance between sides, linkage freedom and oil contamination. Brake design and adjustment vary by tractor and production range.
16. Electrical System
Many tractors have been converted from original charging equipment. Identify actual voltage, polarity, alternator/dynamo and starter wiring before diagnosis.
17. Buying and Restoration Checks
- Cold start from fully cold
- Oil pressure and blow-by
- Gearbox noise
- Clutch and PTO function
- Hydraulic lift under load
- Steering play
- Brake balance
- Previous repairs or mixed components
18. Sensible Restoration Order
- Identify tractor and engine.
- Make engine and cooling system reliable.
- Repair brakes and steering.
- Repair clutch, gearbox and PTO.
- Repair hydraulics.
- Tidy electrics.
- Finish with paint and cosmetics.
