Hydro-Static Power Steering System

TPK Admin Tractor Care Tips
This system is installed in the MF385/385 4WD tractors, which allows the driver/operator to control the steering system with ease. Hydro-static power steering system is a complete power steering system in which there is no mechanical connection between the steering wheel and the front wheels, which allows the steering wheel to be turned with only one or two fingers. This tractor is especially suitable for working with front-end loaders. In this oil system is supplied to the steering control unit through steering pump, due to which controlled quantity of oil reaches the right and left sides by the steering cylinder when the steering wheel is turned; and when the steering wheel is straight, the steering unit bypasses the oil supply.

NOTE:

Always use the reputable and reliable oil in MF350/260/375/385/385 4WD Tractors

A. Neutral Oil Flow When Tractor is Moving Straight
This is the neutral position of the steering unit. In this position the oil flows from the hydraulic pump to the steering unit, and because of the oil spool and sleeve hole being in straight position the oil returns to the steering pump. In this system two shock valves and two suction valves are fitted on the right and left sides of the steering unit. Shock valves are used between the steering rim cylinder and steering ring control unit to protect this system, whereas the suction valves are used to compensate any shortage of oil in the system.

B. Turning of the Steering when the Engine is Running
On first movement of the steering wheel the right and left turning holes become straight with each other, so that oil can be supplied to the oil hand pump. Subsequently, the second movement turns the steering and the hand pump. Simultaneously, the hand pump measures the quantity of oil and pushes it back towards the spool and sleeve. The oil coming back enters the spool valve through the grooves, which connect the holes together straightly so that the oil could go to the direction in which the steering wheel was turned. With the spool valve and sleeve holes being face to face with each other, the oil coming back from the steering cylinder returns to the circuit. The relief valve between the inlet and the spool inside the steering unit, which protects against the high-pressure created inside the pump, for example, due to an obstruction while the front wheels are turning. From the steering pump to the steering unit, there is a check valve installed on the way. This is a one-way valve that prevents high-pressure while the steering is being turned.

C. Turning the Steering when the Engine is OFF
The pump stops working when the engine is turned off, due to which the oil starts to pass through a bypass valve installed inside the steering unit between the supply and return holes. As the pump starts to function, the oil pressure shuts off the valve by pushing it onto its seat. When the pump cylinder is low, the oil returning from the steering cylinder towards the valve inlet side is bypassed. With the help of this function, the oil can move from one side to the other inside the steering cylinder to maintain uninterrupted steering control.

Checking and Changing the Transmission and Hydraulic Oil for tractor

TPK Admin Tractor Care Tips
  • To check the transmission oil, it is important to park the tractor on a level surface and turn off the engine.
  • Remove and clean the small gauge (dipstick) under the driver seat with a cloth.
  • Reinsert and remove the gauge and hold it tilted to check the oil level. In case of low level, replenish the oil.
  • If you plan to use the tractor only to plough or pull trolleys, then maintain the oil level anywhere in the zone marked on the gauge as XX, as shown in the picture labeled ‘B’. if you wish to use the oil in the gearbox to operate any external instruments, for example front blade and tipping trolley etc, then in that case the oil mark should be at the ‘Max’ level ‘C’; as shown in the figure.

Very Important

  • You must have the transmission oil changed after hours from a reputable workshop.
  • Not changing the oil allows the iron dust, mixed with the oil, to ruin the gearbox and the hydraulic system parts.
  • After the first 600 hours, have the transmission oil changed by a recognized workshop.
  • Changing the hydraulic oil after completing every 600 hours, and clean the hydraulic pump filter with diesel.
  • MF240/350 has a capacity of 33 liters for the transmission/hydraulic oil, whereas MF260/375/385 can hold 36 liters, and MF385 4WD reservoir can hold 42 liters.
  • For external hydraulic components in the MF240/350, the oil capacity is 36 liters, whereas 39 liters in MF260/375/385, and 45 liters in MF385 4WD.

Storing the Diesel

TPK Admin Tractor Care Tips
If diesel is to be stored in drums, then tilt the diesel filled drums as shown in the picture below. Front end of the drum must be 3 to 4 inches higher than its rear end, so that all unwanted deposits like sand, rust, dust settle at the back end, and clean diesel comes out from the front.

How to Fill the Diesel Tank of John Deere/ New Holland/ Massey Ferguson Tractor

TPK Admin Tractor Care Tips

Always use uncontaminated diesel; i.e. that does not contain sand, water, kerosene, and other unnecessary elements, because these ruin the costly and delicate parts of the fuel injection pump and automizer which deteriorate engine performance.

To protect the parts described and described above, it is important that you refill the diesel tank after completion of work. Refilling the tank will decrease air in it. The less air in the tank will create fewer water vapors, and the parts will be safe from harm. Never mix oil in the diesel.

Air Lock and how to Remove it from the fuel system of tractor

TPK Admin Tractor Care Tips
If air somehow enters fuel system of the tractor, it stops the fuel-supply and in turn stops the engine. This is called ‘engine is air-locked’. It is important to remove this air from the fuel system before restarting the tractor.

1. Reason for Air-Lock

  • Empty diesel tank.
  • Closed diesel stop-cock.
  • Choked / closed fuel filters.
  • Loose fuel pipes, nuts and bolts.

2. How to Remove the Air-Lock

  • Tighten all pipes and nuts of the fuel system.
  • First open the upper Vent Plug of the primary fuel filter and pump the fuel lift pump of the priming lever, so that airless diesel starts to flow. Close the Vent Plug.
  • Now loosen the two screws on the fuel injection pump and keep moving the priming lever until diesel without air bubble begins to flow out. First tighten the lower screw and then the upper one.
  • First loosen high pressure pump of the cylinder’s the automizer.
  • Start the tractor with the key and tighten the high pressure pipe as the engine sound becomes clearer/ stable.

How to Change the Diesel Filter in Tractor

TPK Admin Tractor Care Tips
Diesel filters are placed on the left side of the tractors. The glass cup filter is called the ‘primary filter’ and the other one is called the ‘secondary filter’. Check the primary filter daily, if you find water or dust in the diesel then manually open the drain tap under the glass cup to drain the dirty diesel. Stop cock of the diesel tap must be open during while draining the diesel. Daily cleaning of the diesel this way protects important and expensive parts like fuel injection pump and atomizers. Before installing the diesel filter, first and foremost it is important to close the diesel tank’s stop-cock. Remove the small bolt on top of the filter body with the key provided, and separate the filter. Replace the small rubber ring with a new ring. Similarly after replacing the two bigger rings place the new diesel filter and tighten the bolt. Open the diesel tank’s stop cock, manual restore the diesel supply in the fuel line by pumping the priming lever of the fuel lift pump.
Very Important Change the diesel filters regularly on timely basis and use only genuine filters. Never use polluted oil.

Checking the Fan-Belt Tension of MF Tractor

TPK Admin Tractor Care Tips

Fan-belt being loose or overly tightened may become a reason to overheat the engine and damage the alternator. Therefore, it is necessary to have the fan-belt tightened to proper tension. To check the tension, pressing the longer portion of the belt (between the alternator and crankshaft pulley as shown in the picture) with a force of approximately 10 pounds should loosen the belt 10mm or ? of an inch.

In case of improper tension in the belt, loosen the alternator and adjusting link nuts, and by pressing the alternator with the help of a lever, tighten the bolts after adjusting the belt’s tension. Check the tension again after tightening the bolts.
Very Important
Always use belts of correct size.
Do not use any kind of oil or grease to mount the belt.

Method of Running-in and Driving the Tractor

TPK Admin Tractor Care Tips
 
  • Do not drive the tractor to farm or home immediately after taking delivery. Have it carried on a truck instead.
  • Operate tractor at 75% load from the beginning. Prior to this, drive the tractor in 3rd gear and at full depth in an already ploughed field
  • If a trolley is to be pulled then 75%, then the trolley could be filled with weight up to 75% of its capacity. After using the tractor for the first 30 hours, have the nearest dealer or authorized workshop service the tractor for the first time.

  Very Important Under no circumstance operate the tractor empty (without load), nor keep the engine running idle for long periods of time.

How to Operate the Tractor

  • Press the clutch pedal completely with your foot, shift the tractor in first gear, and select the smaller levers (Low or High) as needed.
  • Release hand brake
  • Now increase the engine revolution slowly with the help of foot throttle and simultaneous release the clutch slowly until fully released and your foot is off it

Engine Temperature of John Deere/ New Holland/ Massey Ferguson Tractors

TPK Admin Tractor Care Tips

The designated temperature of diesel engine is 80 to 85oC. To maintain this temperature, there is a valve called ‘thermostat’ in the engine. Never detach it from the tractor under any circumstance. Engine parts have been manufactured to operate at a specific temperature, and the engine may be harmed if the temperature falls under or rises above this temperature. Commonly the inexperienced or ill trained mechanics remove this valve from the engine, which cause the engine to operate at cold temperature. Engine operation at low temperature causes faster wear out of the piston rings and liners, and soon the engine becomes useless. Experiments have demonstrated that operating the engine at 40o C instead of 80oC wears out the piston rings twice as fast. Meaning, the service repairs commonly need after four years becomes necessary after just two years. Moreover, the cold engine operation increases the diesel consumption by 5%.
