Massey Ferguson MF 14 & MF 16 Tractors with Mowers Service Manual
This Massey Ferguson MF 14 MF 16 service manual is an instant-download PDF of the shop manual originally published by Massey Ferguson for these hydrostatic garden tractors and their mid-mount mowers. It is Form No. 1448 766 M1, printed May 1975, and it runs 27 numbered pages of procedures, specifications and photos, plus a full-page wiring diagram. Where the operator's manual tells you how to adjust and lubricate the tractor, this one tells you how to take it apart.
About the MF 14 and MF 16
The MF 14 and MF 16 were AMF-built garden tractors sold by Massey Ferguson in the 1970s. Both use a single-cylinder Kohler engine with a 3-1/4" stroke; the manual lists the bore as 3.500" on the MF 14 and 3.750" on the MF 16 (Kohler K321 and K341 respectively, 14 and 16 hp). Both drive through a hydrostatic transmission controlled by the Hydra-Speed lever, with a hi-lo range gear in the rear axle, a hydraulic implement lift, and a three-spindle rotary mower run by an electric implement clutch. Apart from the bore, the two models share almost everything in this manual. For the full spec sheet see our MF 14 & MF 16 specifications.
What This MF 14 MF 16 Service Manual Covers
- Engine: removal and installation, complete disassembly and reassembly, crankshaft and balance gears, cam gear timing marks, valves, seats and guides, pistons, rings and rods, cylinder block and head, governor. Opens with a full page of clearances (crankpin, wrist pin, piston skirt, ring gap and side clearance, valve stem, valve lash, seat and face angles).
- Fuel system: carburetor adjustment, disassembly and reassembly, governor linkage, and the diaphragm fuel pump.
- Ignition system: breaker points and condenser, ignition timing with a continuity light, and the ignition coil.
- Transmission and rear axle: charging pump pressure check (70–150 psi) and shimming, pump and motor separation, swash plate, cylinder blocks, acceleration valves, plus the rear axle, hi-lo shift rail and differential.
- Steering and front axle: steering gear, steering linkage, bellcrank arm and bearings, axle pivot and spindle arm bushings, wheel bearings, and toe-in.
- Hydraulic system: lift pressure check (550–700 psi), control valve and hydraulic cylinder service.
- Mower and mower drive: spindle service, belt routing, and the electric implement drive clutch.
- Transmission linkage checks and adjustments: Hydra-Speed lever and neutral return checks, control rod adjustment for forward or rearward creep, and the spring and cam clearances.
- Trouble-shooting: cause-and-remedy tables for a hydrostatic system that won't move in either direction, works in one direction only, loses power, runs hot, leaks or jerks when starting.
- Wiring diagram: full-page schematic including the regulator rectifier, cranking motor, alternator and implement clutch.
Why This Manual Matters
- The hydrostatic transmission is the expensive part. This manual walks through the pressure check first, then a photo-by-photo teardown of the charge pump, pump, motor and center section, so you can find out whether a weak tractor needs shims or a rebuild.
- Real numbers. Torque values, clearances and pressure ranges as Massey Ferguson printed them, not forum guesswork.
- Covers both models. One manual for the MF 14 and MF 16, with the few differences called out where they matter.
- Pairs with the operator's manual. The MF 14 & MF 16 Operator's Manual covers controls, lubrication and routine adjustments; this manual picks up where it stops.

Frequently Asked Questions
Which tractors does this manual cover?
The Massey Ferguson MF 14 and MF 16 garden tractors and the mower that goes with them. It does not cover the later MF 1450 and MF 1650.
How is this different from the operator's manual?
The operator's manual covers controls, operation, lubrication and owner-level adjustments. This service manual covers repair: engine overhaul, hydrostatic transmission teardown, rear axle and differential, steering, hydraulics and mower spindles. If you want both, the MF 14 & MF 16 manual bundle includes the two together.
Does it cover the hydrostatic transmission?
Yes. It covers the charging pump pressure test, shim adjustment, complete disassembly of the pump, motor and center section, reassembly, the linkage adjustments, and a trouble-shooting table for the hydrostatic system.
Does it cover the engine?
Yes. The engine section includes specifications, removal, complete disassembly and reassembly, and servicing of individual components, plus the fuel and ignition systems.
Is this a printed manual?
No. It is a PDF download available immediately after purchase.
