Massey Ferguson 135: Specs, Horsepower, Parts, Value, and Buying Guide

The Massey Ferguson 135 is one of the most respected classic utility tractors ever built. It is simple, durable, easy to work on, and still useful for small farms, acreage owners, hobby farmers, and collectors.

Even though it is an older tractor, the MF 135 still has strong demand because it offers the kind of straightforward mechanical design many buyers want. No complicated electronics. No modern emissions system. Just a practical 2WD tractor that can mow, rake, haul, grade, pull small implements, and handle general property work.

For anyone looking at a Massey Ferguson 135 for sale, the main questions are simple: How much horsepower does it have? What engine does it use? What is it worth today? Are parts easy to find? And what should you check before buying one?

This guide answers those questions clearly.

Massey Ferguson 135 Specs

The Massey Ferguson 135 was built as a compact utility tractor. Specs can vary slightly by year, country, engine, and transmission, but most models fall into the same basic range.

Specification	Massey Ferguson 135 Details
Tractor type	Utility tractor
Drive	2WD
Engine horsepower	About 45.5–47 hp
PTO horsepower	About 37.7–38 hp
Common engines	Perkins diesel, Perkins gas, Continental gas
PTO speed	540 rpm
Steering	Manual; power steering optional
Brakes	Mechanical drum brakes
Operator station	Open station
Common transmission options	6-speed, 8-speed, 12-speed Multi-Power
Common use	Mowing, light tillage, hauling, grading, hay work

TractorData lists the MF 135 at 45.5 engine horsepower, 33 claimed drawbar horsepower, and 38 claimed PTO horsepower for one common version. A newer TractorData listing shows 47 engine horsepower and 37.7 rated PTO horsepower, depending on model details and source data. (TractorData)

Massey Ferguson 135 Horsepower

The Massey Ferguson 135 horsepower rating puts it in the mid-40 hp utility tractor class. That means it is not a large row-crop tractor, but it is more than enough for many small-farm jobs.

In practical use, the MF 135 can handle:

Job	Suitability
Finish mowing	Good
Brush hogging light grass/weeds	Good with correct mower size
Raking hay	Good
Small square baler work	Possible with proper setup
Light plowing/discing	Good for small acreage
Box blade / rear blade work	Good
Loader work	Possible, but limited compared with modern 4WD tractors

The key is matching the implement to the tractor. A Massey Ferguson 135 can work hard, but it should not be treated like a modern heavy loader tractor or a high-horsepower row-crop machine.

Massey Ferguson 135 Diesel Specs

The Massey Ferguson 135 diesel is usually the most desirable version. Many buyers prefer the Perkins diesel engine because it has a strong reputation for fuel economy, torque, and long service life.

Diesel Spec	Detail
Engine	Perkins 3-cylinder diesel
Displacement	About 2.5L
Engine horsepower	About 45.5 hp
PTO horsepower	About 38 hp
Fuel type	Diesel
Best use	Regular farm and utility work

The diesel version often brings better resale value than the gas version, especially if it starts well, runs cleanly, has good oil pressure, and does not smoke heavily.

Gas vs Diesel Massey Ferguson 135

Both gas and diesel versions can be good tractors, but they appeal to different buyers.

Version	Best For	Things to Watch
Diesel MF 135	Regular work, resale value, fuel economy	Cold starting, injector pump, smoke, blow-by
Gas MF 135	Light use, hobby farms, easier basic fuel repairs	Carburetor issues, ignition problems, fuel system age

For most buyers, a clean Massey Ferguson 135 diesel is the stronger choice. But a well-maintained gas model can still be a reliable and affordable tractor.

Massey Ferguson 135 Transmission Options

The MF 135 came with several transmission setups. The most common are 6-speed, 8-speed, and 12-speed Multi-Power versions. TractorData lists these transmission options for the model.

Transmission	What to Know
6-speed	Simple and common
8-speed	Gives more gear flexibility
12-speed Multi-Power	Useful, but repair condition matters more

When buying, do not focus only on the number of gears. Check how the tractor shifts. It should not grind badly, jump out of gear, slip, or feel weak under load.

Massey Ferguson 135 Weight and Size

The Massey Ferguson 135 weight is usually around the 3,000 lb range, depending on configuration, engine, tires, ballast, and attachments. This makes it heavy enough for useful traction but still small enough for many barns, small fields, and acreage jobs.

If the tractor has filled rear tires, wheel weights, or a loader, the real transport weight can be much higher. Always check the actual machine before choosing a trailer.

Massey Ferguson 135 Tire Size

Rear tire size can vary because many MF 135 tractors have had tires replaced over the years. Common rear tire sizes include sizes around 12.4-28 or 13.6-28, depending on setup and market.

Before buying rear tires, check the size stamped on the sidewall. Do not assume the tractor still has its original tire size.

Massey Ferguson 135 Value and Price

As of 2026, the Massey Ferguson 135 value depends heavily on condition, engine, tires, hydraulics, power steering, loader, and location.

Current U.S. listings show a wide price range. TractorHouse lists used Massey Ferguson 135 tractors from about $1,900 to $10,755, with examples including running tractors around $3,000–$7,000 and higher-priced clean or better-equipped units. Machinery Pete shows current MF 135 listings from about $1,950 to $4,295, which is closer to the typical price range for basic used examples.

Condition	2026 Estimated Price Range
Non-running / project tractor	$1,500–$2,500
Running but rough	$2,500–$4,000
Good working tractor	$4,000–$6,500
Clean diesel model	$5,500–$8,000
Restored or loader-equipped model	$7,000–$10,000+

A cheaper tractor is not always the better buy. Bad rear tires, weak hydraulics, clutch problems, poor wiring, or a tired engine can quickly turn a low purchase price into an expensive repair project.

Massey Ferguson 135 Parts

Parts support is one of the biggest advantages of owning a Massey Ferguson 135. Since the tractor is still widely used, many common replacement parts are available through aftermarket suppliers, salvage yards, online parts stores, and tractor dealers.

Common parts include:

Part	Why It Matters
Oil filter	Routine maintenance
Fuel filter	Prevents fuel delivery problems
Air filter	Important for dusty mowing and field work
Starter	Common age-related replacement
Radiator	Needed if overheating or leaking
Carburetor	Mainly for gas models
Hydraulic pump	Important for weak lift problems
Seat	Common comfort/restoration upgrade
Wiring harness	Useful when old wiring is damaged

This strong parts availability makes the MF 135 easier to keep running than many less common vintage tractors.

Massey Ferguson 135 Hydraulic System

The hydraulic system is one of the most important things to check before buying a used MF 135. The 3-point hitch should lift smoothly, hold an implement without dropping quickly, and respond properly to the control lever.

Common hydraulic problems include:

Problem	Possible Cause
3-point hitch will not lift	Low fluid, worn pump, stuck valve, internal leak
Hitch lifts slowly	Dirty oil, weak pump, worn seals
Hitch drops under load	Internal leakage or worn cylinder seals
Noisy hydraulics	Low oil or pump wear
Milky hydraulic oil	Water contamination

Do not replace the hydraulic pump immediately without checking the basics first. Fluid level, oil condition, filters/screens, linkage adjustment, and leaks should all be inspected.

Massey Ferguson 135 Loader

A Massey Ferguson 135 loader can be useful for light-duty work, but buyers should understand the limits. The MF 135 is a 2WD utility tractor, not a modern 4WD loader machine.

A loader adds stress to the front axle, steering, clutch, brakes, and hydraulics. If you are buying a loader-equipped MF 135, inspect it carefully.

Loader Area	What to Check
Front axle	Wear, cracks, loose parts
Steering	Excessive play or hard steering
Loader frame	Welds, cracks, mounting points
Hydraulics	Slow lift, leaks, weak response
Rear ballast	Needed for safer loader use
Brakes	Must stop evenly and safely

For mulch, manure, light gravel, snow, and general property chores, a loader can be handy. For heavy digging or constant loader work, a newer 4WD tractor is a better choice.

Massey Ferguson 135 Wiring and Electrical Issues

Electrical problems are common on older tractors, mostly because wiring gets old, modified, or poorly repaired. A Massey Ferguson 135 wiring diagram can help, but the first step is usually a visual inspection.

Check for:

Issue	Why It Matters
Loose grounds	Can cause no-start or weak charging
Brittle wires	Fire and reliability risk
Bypassed switches	Safety concern
Weak battery cables	Hard starting
Poor alternator/generator wiring	Charging problems

A tractor may still run with messy wiring, but poor electrical work can create frustrating starting and charging issues.

Massey Ferguson 135 Serial Number Location

The Massey Ferguson 135 serial number location is important when confirming the tractor’s year and identity. On many models, the serial plate is found around the dashboard, instrument panel, or lower dash area.

Because these tractors are old, the plate may be painted over, damaged, replaced, or missing. If the serial number is unreadable, check engine tags, casting numbers, and any paperwork the seller has.

Common Massey Ferguson 135 Problems

The MF 135 has a strong reputation, but age still matters. Most problems are related to wear, neglected maintenance, or old repairs.

Problem	What to Check
Hard starting	Battery, cables, starter, fuel system, compression
Heavy smoke	Engine wear, injector issues, fuel problems
Weak hydraulics	Oil condition, pump, seals, internal leakage
Bad brakes	Wear, adjustment, oil contamination
Steering play	Steering box, tie rods, front axle
Overheating	Radiator, thermostat, water pump, blocked fins
Clutch slipping	Wear or adjustment issue
Gear noise	Transmission wear or low/dirty oil

The best MF 135 is not necessarily the one with the best paint. It is the one that starts well, shifts cleanly, stops safely, lifts properly, and has solid tires.

Buying a Used Massey Ferguson 135

Before buying a used Massey Ferguson 135, inspect it like a working machine, not just a collectible.

Use this checklist:

Area	What to Look For
Cold start	Should start without excessive smoke or long cranking
Engine	Listen for knocks, check leaks and blow-by
Transmission	Test every gear
Clutch	Should engage smoothly without slipping
PTO	Should engage and operate correctly
Hydraulics	Test the 3-point hitch with weight if possible
Brakes	Both sides should stop evenly
Steering	Check looseness and front axle wear
Tires	Rear tires are expensive, so inspect carefully
Wiring	Look for unsafe repairs
Loader	Check frame, hydraulics, steering, and front axle
Serial number	Verify identity and model year if possible

If you cannot test the tractor under load, price it carefully. A tractor that “runs good” in a seller’s yard may still show problems once it is attached to a mower, blade, or implement.

Is the Massey Ferguson 135 Still Worth Buying?

Yes, the Massey Ferguson 135 is still worth buying if you want a simple, useful, affordable classic tractor. It is especially attractive for small farms, homesteads, collectors, and property owners who want a machine they can maintain without modern electronics.

The best value is usually a diesel model in good mechanical condition with strong hydraulics, decent tires, working PTO, clean shifting, and safe brakes. A restored tractor can be nice, but mechanical condition matters more than paint.

For buyers comparing Massey Ferguson 135 specs, horsepower, price, parts, and problems, the conclusion is clear: the MF 135 remains one of the most practical classic utility tractors on the used market.
