Massey Ferguson 135 Draft Control Adjustment: A Step-by-Step Guide

====================================================================================

The draft control system in your Massey Ferguson MF 135 tractor is essential for efficient pulling of heavy loads, such as trailers or plows. Proper adjustment ensures smooth operation and prevents damage to the transmission components.

In this article, we'll walk you through a step-by-step guide on how to adjust the draft control on your MF 135 tractor.

### Tools Required

* Phillips-head screwdriver

* Flat wrench (if needed)

### Safety Precautions

1. Always park the tractor on level ground and engage the parking brake before starting any adjustments.

2. Wear appropriate protective gear, including gloves and safety glasses.

3. Make sure all bystanders are at a safe distance from the working area.

## Step 1: Locate the Brake Adjustment Screw

---------------------------------------------------------------------

The first step is to locate the brake adjustment screw on your MF 135 tractor's left side near the transmission assembly. It should be identified by its round, black appearance and Phillips head design.

### Tips:

* Consult your Massey Ferguson manual if you're unsure about the exact location of this component.

* If necessary, refer to a workshop guide for specific instructions tailored to your model year or trim level.

## Step 2: Remove the Adjuster Screw

---------------------------------------------------------------------

Using a Phillips-head screwdriver, carefully remove the adjuster nut from its housing on the brake assembly. Be mindful not to strip any threads during this process.

### Tips:

* Apply penetrating lubricant if necessary before attempting removal.

* Keep track of all screws and washers removed for reassembly purposes later.

## Step 3: Engage the Brake Shoe with the Drum

---------------------------------------------------------------------

Turn the adjuster screw clockwise very slowly until you feel resistance as the adjustment nut on the brake shoe comes into contact with the drum. This engagement marks the starting point for your subsequent adjustments.

### Tips:

* Be patient and gentle during this step to avoid over-tightening, which could lead to premature wear or damage.

* If necessary, refer back to your Massey Ferguson manual for detailed illustrations of this procedure.

## Step 4: Adjust the Brake Shoe Clearance

----------------------------------------------------------------------

Continue turning the adjuster screw clockwise in small increments until you achieve the desired clearance between the brake shoe and drum. The goal is to allow just enough movement without touching or binding against each other under normal operating conditions.

### Tips:

* Consult your Massey Ferguson manual for specific recommendations on ideal clearance values based on load capacity, terrain type etc.

* Keep a close eye on wear patterns across both components as over- or under-adjustment can lead to premature component failure.

## Step 5: Finalize the Adjustment

---------------------------------------------------------------------

Once you've achieved the desired brake shoe clearance, tighten the adjuster nut by hand using your wrench (if provided). Double-check that all bolts are securely fastened before proceeding with further testing and fine-tuning as necessary.

### Tips:

* Make sure to reapply lubricant according to manufacturer's instructions after each adjustment cycle.

* Test drive your MF 135 tractor under various loads and conditions to ensure smooth operation, proper engagement/ disengagement of the draft control system, and absence of any unusual noises or vibrations indicating improper adjustments.
