Farmers looking for a solid mid-size machine often point to the Fiat 640 tractor. It produces about 75 to 85 horsepower, making it a strong choice for medium to large farms. People want real facts about specs and prices before spending their hard-earned money.
This guide breaks down the engine details, hydraulic strength, and where to find good parts. We keep the technical talk simple and easy to understand. Knowing exactly what you are buying saves you from expensive mistakes later.
Power and Capability for Demanding Work
This tractor sits right in the utility category with serious pulling muscle. The four-cylinder diesel engine handles deep plowing and heavy transport without breaking a sweat. The design skips fancy gadgets in favor of pure durability. It is built for farmers who need a machine that just works every single day.
- Key performance characteristics:
- 75 to 85 HP gives you plenty of power for commercial jobs.
- Four-cylinder engine runs smoothly and delivers strong low-end torque.
- Direct fuel injection burns diesel cleanly and cuts down on waste.
- Gear-type transmission gives you the right speed for any field condition.
- Two-wheel drive keeps the mechanics simple and repair costs low.
- Strong hydraulics lift heavy implements without struggling or stalling.
Owners report steady performance year after year. You do not need premium fuel or special care routines. Local mechanics know this engine inside and out. Parts are easy to find across farming regions.
- Engine Design and Hydraulic System
The powerplant relies on a proven four-stroke diesel setup. Direct injection sends fuel straight into the chamber for better efficiency. The engine hits peak power at normal working RPMs without straining.
| Specification | Value |
| Engine Type | Fiat 4-stroke, direct-injection 4-cylinder |
| Horsepower | 75-85 HP |
| Hydraulic Pump | 26.7 liters per minute |
| Hydraulic Control | Draft and position control |
| Drive Type | 2-Wheel Drive (2WD) |
| Transmission | Multiple forward and reverse gears |
The hydraulic setup offers both draft and position control. Draft control adjusts the plow depth automatically based on soil hardness. Position control lets you lock the implement at a set height. The pump pushes 26.7 liters of oil per minute. That is plenty of flow for standard Category II farm tools.
Built for Long-Term Reliability
Al Ghazi designed this machine to be simple and tough. You will not find fragile computer boards or complex electronics here. The mechanical parts are built to take a beating for years.
- Durability features:
- Heavy rear axle carries big loads without bending or snapping.
- Strong brakes stop the tractor safely, even when pulling a full trailer.
- Five-bearing crankshaft adds serious strength to the engine's core.
- Basic electrical system means fewer wire failures in dusty conditions.
- Thick steel frame resists twisting when you hit rough ground.
- Shielded hydraulic lines stay safe from flying rocks and branches.
These choices keep the tractor running when conditions get nasty. You do not have to baby it. It handles mud, heavy loads, and long shifts without complaining.
- Fuel Economy and Operating Costs
Running costs matter just as much as the sticker price. The Fiat 640 has a good reputation for sipping fuel. Direct injection and clean burning help keep your daily expenses down.
- Low fuel use compared to older, less efficient models.
- Clean combustion gets the most work out of every liter of diesel.
- Standard oil capacity keeps lubricant costs reasonable during changes.
- Long service intervals mean fewer trips to the workshop.
- Common parts are cheap and easy to source locally.
Operators often finish a full day's work on a single tank. The engine does not burn oil between scheduled changes. All these small factors add up to major savings over the tractor's life.
- Compatibility with Farm Implements
This tractor hooks up to standard equipment found on most farms. The three-point hitch meets international standards for Category II tools.
- Common implements used with this tractor:
- Cultivators for breaking up soil and killing weeds.
- Plows for deep, primary tillage work.
- Harrows for smoothing the field before planting.
- Trailers and tippers for moving heavy loads and haulage.
- Seed drills for accurate and fast planting.
- Water pumps driven directly by the rear PTO shaft.
The PTO spins at a standard 540 RPM. You can run threshers, generators, and other PTO tools without any mods. Hydraulic remotes let you control cylinders on advanced implements easily.
Parts Availability and Component Support
Keeping a tractor on the road requires good replacement parts. Chenab Engineering builds heavy-duty castings for Fiat tractors and New Holland models. These components meet strict quality checks and fit right the first time.
- Oil Sump 240:
This heavy pan sits at the very bottom of the engine to hold your motor oil safely. It takes a lot of abuse from flying rocks and rough ground while you are working in the field. We cast these with extra-thick walls so they resist dents and stop oil leaks before they start. The flat machined surface creates a tight seal with the gasket to keep dirt and dust out of your engine.
- Front Support MF 240:
This solid casting bolts the engine block directly to the front axle on the MF 240. It absorbs all the steering stress and carries the heavy weight of the front end during daily chores. We pour it from high-grade iron and machine the bolt holes perfectly so it drops right into place. A tough heat treatment process keeps the metal from cracking when you pull heavy loads through tough soil.
- Support Splitter Fiat 480
This massive piece of iron sits between the transmission and the rear axle on the Fiat 480. It handles the full twisting force of the engine when you are pulling deep plows or heavy trailers. We use premium metal and strict heat treatment to make sure it never bends or snaps under pressure. Our CNC machines cut the exact bolt patterns so your mechanic can install it quickly without any guesswork.
- Pivot Diff Lock
This small but tough component engages the differential lock when you need extra grip in the mud. It allows both rear wheels to lock together so you can pull yourself out of slippery or wet soil. We cast it from high-strength iron to resist bending when the drivetrain is under heavy strain. Precision machining keeps the moving parts smooth so the lock engages easily every time you press the pedal.
- Front Support 350
This casting connects the engine to the front axle on the MF 350 and similar models. It takes on all the steering forces while supporting the heavy front-end weight of the tractor. We machine every single support to exact OEM specifications for a perfect, drop-in fit. Our foundry uses high-grade iron that stands up to the daily beating of rough farming.
- Water Outlet Connection
This fitting directs hot coolant from your engine block up to the radiator to keep things cool. It must withstand high operating temperatures and constant system pressure without ever leaking. We cast these connections with extra-thick walls to resist cracking from severe thermal stress. The machined surfaces are perfectly flat to guarantee a tight, leak-proof seal with your radiator hose.
