How do you go about lowering the height of the clutch pedal? I would like to reach the pedal without hitting my chin with my knee.
This is a dual clutch unit. Any advice is welcome. Jim.

I am not sure if the 50 shares this feature with the 65 or not.

On the 65 you can move the clevis pin on the clutch rod to the other hole that is provided. Doing so yields a lower clutch pedal BUT will not allow the second stage of the clutch to release.

So this may or may not help your situation.

Another fix is that you can adjust the 2-stage clutch closer together, whereas the second stage starts to disengage sooner. That would be done through the bottom inspection cover and you would adjust the gap on the three set screws to a lesser amount. Then you would have to readjust the clutch pedal rod to get the lower pedal height. Should you decide to go this route, it is important that the set screws are as close as possible to the same height.

Of course what I just told you goes against what you will read in the service manual, but a lower pedal is worth it to me.

Like Eric, I can't vouch that the English models with 11" dual clutches are the same as the MF50's, but, as a rule, if the pedal height is getting excessively high, this can be a sign of main plate wear.
If this is not a possibility, then I can recommend Eric's advice. Close up the gap on the 2nd stage. But you MUST maintain some clearance, otherwise the PTO drive plate will slip under heavy loading.
This will give you at least temporary relief from a sore chin.
Evan.

Where the pedal is bolted to shaft(at housing) loosen bolt, put a punch or small rod in hole on end shaft to keep pressure on clutch. Move pedal to position tighten bolt. Move shaft clockwise to adjust clutch.

In 1963 they changed the design of the clutch pedal, brake pedals and running boards on the MF50. This resulted in a higher clutch pedal compared to the earlier design. If you have the later design, there is a pin you can move to a different hole in the clutch linkage that will leave the second stage clutch constantly engaged and will lower the pedal to a more comfortable position. If you aren't doing any PTO work you can leave it there most of the time. The first picture shows a 1964 MF50 clutch pedal height with the pin in the two stage operation position. The second picture is a 1959 MF50. You can see the difference in height compared to the top of the transmission housing. I like the older design much better.

The instruction I gave was for the older 50.

Thanks for the replies. My tractor is a 1964 so it looks like the red one pictured. The gap on the release arm is more than the 1/8 inch illustrated in the owners manual, so an adjustment is needed. Will play with the pedal height.Jim.
