Massey Ferguson 135 Adjustment Questions

How to Adjust a Massey Ferguson 135 Lift?

Massey Ferguson 135 tractors come with the Advanced Ferguson Hydraulic System plus a 3-point hitch. These two are needed to control or operate different implements or attachments. Adjustment on the MF 135 lift is done via the Advanced Ferguson Hydraulic System and 3-Point Hitch with Position, Draft, Pressure, and Response Controls. 

This hydraulic system can handle category 1 three-point hitch implements. It has a constant pumping feature that allows the operation of auxiliary hydraulic control valves and remote hydraulic cylinders. 

The Draft Control is needed when you are using an implement that needs to have a uniform working depth. The Response Control works together with Draft Control and handles the rate of the hitch implements and Draft Control System.

The Position Control is needed to operate 3-point hitch-mounted tools that are not controlled by the Draft Control. Implements like soil scoopers, cranes, and hole diggers require Position Control. Pressure Control or the Universal Pressure Control Hitch is used to control pull-type implements. This provides tractive weight.

All these hydraulics controls work together to provide lift and other movements to different accessories and implements. It’s therefore very important to use accessories and attachments that work specifically with a Massey Ferguson 135 tractor. 

How to Adjust Brakes on Massey Ferguson 135?

One of the most important parts of regular Massey Ferguson 135 tractor maintenance is to make sure that the brakes are in good working order. You must also know how to adjust the brakes on-site in case you need to troubleshoot any braking problems. 

First, raise the two rear wheels from the ground. Find the brake adjusting holes and remove the covers. Use a screwdriver to tighten the adjusting screws. Move these until these are tight and the wheels are unable to move. 

Back the screws until you don’t feel any drag from the drums. You should check the drums every time you click to back the screws. You may now place the tractor rear wheels down and test the master brakes.

You should check the master brake with both brake pedals locked. Apply the brake while driving in a flat area. The master brake is set when the tractor stops on a straight line. If you find the tractor pulling to one side, adjust the brake linkage on that side. You may shorten or lengthen the linkage so that the tractor brakes on a straight line. You may also ask a tractor specialist to help you make adjustments. 

How to Adjust Clutch on Massey Ferguson 135?


Similar to the clutch that is used in a car, the Massey Ferguson 135 clutch is also dented while altering the tractor from one gear to another gear. However, if the defiance of the clutch starts to deplete through time, it may be necessary to do an adjustment on the clutch. It is highly recommended that you consider adjusting the clutch first before deciding to immediately replace it.


If you do not know how to adjust the clutch on Massey Ferguson 135, here are the steps that you can try:


  • Take off the belt cover from the clutch pump of the tractor by using a socket set.
  • Disengage the bolts in the clutch pump to ease the belt.
  • Adjust the belt to make it properly attached to the pulleys and pull the clutch pump assembly heading to the right using a huge screwdriver to heighten the tension in the belt.
  • Fasten the bolts of the clutch pump and change the belt using a socket set.


By doing the above steps, you should be able to adjust the clutch on Massey Ferguson 135. The steps are relatively easy so you should be good to go.


How to Adjust Internal Hydraulic Linkage on A Massey Ferguson 135?

The Massey Ferguson 135 tractor is a utility tractor manufactured by MF from 1964 to 1975. This is a very popular tractor because of its strength, reliability, and power. With regular maintenance, the 135 can last for many years.

A part of regular tractor maintenance is adjusting the internal hydraulics. The hydraulic controls are held by friction washers. These components are spring-loaded and thus, will wear and tear after considerable use. Older 135 tractors and those that are used more often tend to develop “creeping” washers and thus, the hydraulic controls lose their ideal setting.

To remedy this, tighten the screw on every lever. The screw holds the friction washer. You should tighten this until you achieve the desired tension level. 

A part of the Massey Ferguson 135 tractor general maintenance is checking the hydraulic system at least every 10 hours of use or after a day’s use. Every 50 hours, drain the “brake-in” oil. Afterward, refill with new Massey Ferguson M-1129-A hydraulic oil. And every 200 hours, the hydraulic rock shaft must be lubricated with lithium-base grease at least one to three shots. You may also ask the help of a tractor specialist to help you make adjustments.


How to Adjust Massey Ferguson 135 Steering Gearbox?

The Massey Ferguson 135 tractor offers the power and manual steering which should be regularly adjusted and maintained to ensure safe and reliable steering controls.  Manual steering models were manufactured in the United States, France, Great Britain, Spain, and Germany. These were shipped in different periods and had different specs. 

U.S.-made Massey Ferguson 135 tractors hash a single manual steering gearbox with axial positioner bolts similar to power steering boxes. Look closely and you will see that the segments on the gears are tapered. Move the gears endways and you will be able to adjust the gearbox.

A part of power steering adjustments is to change the hydraulic oil. Use M-1129-A, the recommended oil by Massey Ferguson. Always avoid air from entering the system as this can damage it.

To change hydraulic oil, start the tractor and warm-up the engine until it reaches its operating temperature. Turn your steering wheel to the right, and then to the left side. Do this three times. Place the wheels forward on a straight line and place oil in the reservoir. Do not turn off the engine. Repeat the steps to make sure that there is no air present in the system.

How to Adjust the Carburettor on a 4 Cylinder 135 Massey Ferguson Tractor?

One of the most important parts of tractor maintenance is adjusting the carburetor. In a Massey Ferguson 135 tractor with a 4-cylinder Continental gasoline engine, adjustments must be done correctly to ensure the best performance. 

Three adjustments are found on the carburetor. A small needle screw is for the idle mixture screw while it’s open at the 7/8 turn from the closed position. 

The main jet is a large needle screw and should be set initially open at the 1 ¼ turn from a completely closed position. 

The third screw is the wing-headed screw found at the rear end of the carburetor. This is usually set at 450 RPM. So, start your tractor and allow the engine to warm up. Place the idle speed to 450 RPM. You may now adjust the third screw, idle speed screw to get the smoothest and the highest idle speeds. You may also use a vacuum gauge. Obtain the steadiest vacuum reading and place the idle speed to 450 RPM.

Meanwhile, the main jet screw must be set while the vehicle is under load. Simply adjust the throttle from half to full open. If your engine stalls, the mixture is lean. Adjust to a 1/8 opening and test it again.   

How to Adjustment Clutch Pedal on Massey Ferguson

The clutch pedal on a Massey Ferguson may be adjusted right through the hole that is located at the bottom part of the clutch housing. You will also notice that the transmission clutch can be adjusted by means of loosening the clamp bolt that is located on the clutch shaft. It can also be accomplished by turning the yoke just a bit on the shaft. After completing the process, you will notice whether the clutch pedal has been properly adjusted if it has two or three inches of clearance. 

The clutch pedal needs to have enough travel in order to release both the first and second stages prior to having contact with the footrest plate. After the second stage is completed, there should not be too much travel because it will only depress the fingers of the pedal plate too far that it may be possible to have contact with the plate center rivets. 

The process of adjusting the clutch pedal on Massey Ferguson is a general one. However, it is still advised to check on the specific Massey Ferguson model for specific instructions. This can be done by looking at the manual of the vehicle for details. 

How to Bypass Depressing Clutch to Start Massey Ferguson 135


When bypassing depressing clutch in order to start a Massey Ferguson 135, it is important to observe proper safety procedures. Before you mount the tractor, make sure that the shields and guards are set in place, and working well. There are rails that are provided to mount and dismount. If needed, adjust the seat of the operator for a fit and easier access to controls. 


There are things that need to remember before the engine is started. This includes placing the lever of the gearshift in “park” or “neutral”. Also, it is important to ensure that all hydraulic controls are placed in neutral, with the PTO disengaged. Apply the brakes afterward, and depress the clutch pedal. 


The tractor will start with the gear when the usual starting circuitry is bypassed. The engine can be started from the seat of the operator while the transmission is in the park. Avoid starting the engine by shorting on the starter terminals. Also, it is a good reminder to avoid starting the engine while on the ground, standing. 


While bypassing depressing clutch to start your Massey Ferguson 135, it is recommended not to have extra riders around, and make sure to wear protective gear. 

How to Bypass Neutral Shift to Start Massey Ferguson 135


The neutral shift on a Massey Ferguson 135 is not a necessity, which is why bypassing it may be easy. This switch is usually located right beneath the shifter in the column. It is plugged into the wiring harness of the vehicle. Note that if you need to bypass the neutral shift in order to start your Massey Ferguson 135, it is recommended not to do so using homemade wiring. It is best to consult a dealer if the neutral sift is malfunctioning. 

  • Locate the neutral safety switch on the MF135
  • With a ¼-inch open-end wrench, turn the switch counterclockwise in order to loosen the nut lock.
  • A crescent wrench can be used in turning the adjustment screw in a clockwise direction until it becomes clear from the clutch pedal.
  • Use wire pliers in cutting the black and red wire that comes from the switch. 

If there is a need to remove the neutral safety switch, you can remove the attached shifter linkage. This can be attached using a bolt and lock nut or using a cotter pin or boss pin. Remove the bolts that mount the neutral safety switch. 

How to Fix Flooding 135 Massey Ferguson?


Flooding on your Massey Ferguson 135 shouldn’t be taken for granted. You have to immediately proceed with the necessary fixing to avoid further damage. If you are clueless on how to fix flooding in your MF135, here are some common ideas that could help you:

  • The first thing to know is that replacing the carb is not the immediate option. With proper cleaning and a certain task carried out on the float valve system, you can fix the flooding.
  • Another approach that you may consider doing is shutting off the fuel valve at the tank to inhibit a hung float from stuffing the engine with a lot of fuel once the engine is not running. 
  • The float may have some leaking and it is stuffed with fuel which causes the fuel bowl to flood constantly considering that the float will not rise and the fuel will not shut off.
  • It is also possible that you have a working float but there is an incorrect adjustment on its level which is not permitting the float valve to shut off.
  • Lastly, you may need to replace the float valve once you confirm that it is damaged.


How to Service a Massey Ferguson 135?


Servicing a Massey Ferguson 135 is not that exhausting. Here are the basic things that you should do when servicing your tractor:


  • Check whether the engine oil is on the level ground. If you find it needed, fill it.
  • Check the primary fuel filter glass bowl. If you find any traces of water, drain it off.
  • Check the level of the coolant used in the radiator. Fill within the range of 37mm from the radiator’s top portion.
  • Lubricate the front hubs and front axle spindles.
  • Lubricate the lift arms and leveling box.
  • Lubricate the front axle pivots pin.
  • Lubricate the brake pedal bearing assembly.
  • Inspect the oil level of the belt pulley when in use. If you find it necessary, fill it to plug level and make sure to only use the suggested transmission oil.
  • Inspect the tire pressure and adjust it to make it fit for the existing job.


Servicing your Massey Ferguson 135 is crucial to keep the machine operate efficiently and smoothly. This service is suggested to be carried out either every 10 hours or daily. If the machine is used for entire day work, it would be easier to perform daily servicing.



How to Widen Front Axle on 135 Massey Ferguson

In order to widen the front axle spacing on a 135 Massey Ferguson, here are some steps that you can follow:

  1. Lift your tractor from the ground.
  2. Detach the two bolts while making sure that each of the front axle arms is secured towards the center axle. You can then loosen the tie rod set screw.
  3. After, you can move the axle arms in order to achieve the tread width desired, while taking into consideration the center axle.
  4. Make sure that the tie rod is adjusted to a point where the bolt centers with the appropriate notch of the rod, and the wheels are also straight ahead.
  5. Replace the two bolts in every axle arm, tightening the bolt on the tie rod.

There are 2 pieces of tie rods on every side. There is also a clamp with a bolt holding them together. It would be best to loosen them up to remove the bold. The tie rod segments need to be telescope to the points where the indentions are ready to be re-installed. At times, the segments may size, though they can be adjusted to move.


Massey Ferguson 135 PTO Not Engaging When On

To engage the PTO of a Massey Ferguson 135 tractor, you simply flip the toggle switch of the PTO to the “on” position. This should be done while pressing down the clutch pedal. Depending on the type of chassis on the tractor, the PTO switch can be found on the dashboard that is located right above the transmission shift lever. It is easy to identify because it has the label “PTO”. Release the clutch pedal slowly until the hydraulics engaging can be heard.

However, the problem can happen if the PTO cannot engage when on. Some owners report having the need to engage the PTO as the engine is turned off, cranking it while engaged. This could be dangerous and may result in some bad things happening. To some, this happens after clutch replacement. In order to solve this problem, it is recommended to set up the PTO clutch accordingly.

To complete a PTO adjustment, you can refer to the manual of the Massey Ferguson 135 tractor. Among the tools that you would need include two 5/16 open -end wrenches since the lock nuts are typically very tight after rounding off the corners on the nuts and bolts.
