Massey Ferguson MF 42 Operators Manual – Factory Specs for Agricultural Tractor

Description

Trying to find the correct hydraulic fluid capacity for a Massey Ferguson MF 42 without the manual is a waste of time. Guessing on PTO engagement procedure can damage the gearbox. That is why I keep a copy of the factory Operators Manual within arm’s reach on the workbench. This Massey Ferguson MF 42 Operators Manual is the same document that came from the factory with the tractor. It has 36 pages of specifications, operating instructions, and maintenance data. No rewrites. No aftermarket interpretations.

36 Pages: Factory Content Breakdown

Chapter I starts on page 5 with the complete engine and drivetrain specifications. The Perkins 3.152 three-cylinder diesel has a 3.6-inch bore, 5.0-inch stroke, and 152.6 cubic inch displacement. Compression ratio is 17.4:1. Firing order 1-2-3. Idle at 600 rpm, full load at 2250. These numbers matter when you order piston rings or set the injection pump timing. The manual transmission section explains the 6-forward, 2-reverse gearbox and the optional instant reduction device that drops speed 30% in any gear to handle tough spots.

Massey Ferguson MF 42 Operators Manual – What You Need to Know

This manual covers both the standard and the Etroit (narrow-track) versions. The introduction spells out the differences: the Etroit model cannot take a front loader but accepts specialized viticulture implements like the 853 plow with six bottoms. Everything from the three-point hitch geometry to the wheel track adjustments is in here. You get the same diagrams the dealer would have shown your grandfather when he bought the tractor new. No guessing on hydraulic system pressure because the Ferguson system specs are right there.

Controls, Instruments, and Starting Procedure (Chapters II & III)

Chapter II (page 10) covers the driver station layout: the stop control, throttle quadrant, clutch and brake pedals, the dashboard telltale lights. Chapter III (page 17) walks through the cold start sequence: glow plug preheat, throttle setting, PTO engagement order. Many clutch failures I have seen trace back to someone skipping the double-clutch step when engaging the PTO. The manual shows you the sequence. The Manual Transmission shift pattern is diagrammed so you never grind gears.

Implement Attachment and PTO Usage (Chapters IV & V)

Chapter IV (page 20) covers hitching drawbar implements and the three-point linkage. The lift capacity, draft control sensitivity, and top link settings are detailed. Chapter V (page 26) covers field operation: plowing with a three-bottom plow, using the Ferguson system to maintain constant depth. The PTO can be either engine-speed or ground-speed proportional. The chapter warns against engaging the PTO while the tractor is moving if the implement has a shear bolt. The Manual Transmission section in Chapter V explains how to use the instant reduction device without stopping.

Maintenance and Adjustments – Chapters VII and VIII

Routine service intervals live in Chapter VII (page 41). Oil change every 150 hours, fuel filter every 300 hours, valve adjustment every 600 hours. The torque table on page 41 lists cylinder head bolts, main bearing caps, connecting rods, flywheel, and wheel lug nuts. Chapter VIII (page 53) covers clutch free-play adjustment, brake rod linkage, front wheel toe-in, and wheel track width settings. Pull the manual out before you turn a wrench; aftermarket specs can be off by 10 percent on critical fasteners.

Why Does the OEM Manual Matter More Than a Photocopy?

Third-party manuals often get the little details wrong – they miss the Etroit model’s front axle weight limitations or the specific PTO shaft length for the 853 plow. This factory-original Operators Manual is a direct scan of the Massey Ferguson publication. The diagrams are clear, the warning labels about hot exhaust and PTO shields are exactly as printed. When a bearing cap needs 12.5 kg·m (about 90 ft·lb), you want the number from the source, not a rounded approximation. This 36-page document is the authoritative spec sheet for your MF 42.

Is the MF 42 Operators Manual in English?

The manual is in French. However, the diagrams, tables, and torque specifications are language-independent. You can follow the procedures by matching illustrations.

Does it cover the MF 42 standard and narrow-track Etroit models?

Yes. The manual describes both the standard and narrow-track Etroit variants in the introduction. The chapters apply to both, with specific notes for the Etroit model, especially regarding front axle and implement compatibility. For example, the front loader cannot be fitted to the Etroit, but the three-point hitch dimensions are identical. The wiring and controls are the same for both. The manual also notes that specialized viticulture implements like the 853 plow with 6 bodies are compatible with the Etroit version.

What torque specifications are included?

The manual provides torque values in kg·m (kilogram-meters) for cylinder head fasteners, main bearing caps, connecting rod bolts, flywheel bolts, and wheel lug nuts. Page 5 gives the engine specs and page 41 has the maintenance torque data. You can convert to ft-lbs using a conversion chart.

Can I use this manual for the MF 35 or MF 50?

Not directly. The MF 42 has its own engine and transmission specs. Use a model-specific manual.
