MF 135 Quit Pulling - Please HELP

[RTR]

Was moving the little tractor around (no load) and when we let out on the clutch something popped and it all of a sudden quit pulling in forward and reverse (all gears high and low). Clutch pedal feels normal and doesn't make any weird noises. You can still engage the PTO by pressing the clutch pedal. You can put the tractor in all gears, but it just doesn't move. If you try to put it in gear without pressing clutch, it will try to grind just a little and wont go in. An aftermarket clutch was installed by the previous owner a couple years ago.

Greatest liklihood is the split pin fallen out of the shear tube and its slid forward and disengaged.

Thank you all for the responses. I don't know if I was clear or not, but the PTO still works as it should and engages when you depress the clutch pedal and operate the engagement lever. The tractor does not move though.

Answer..
That is why the problem may be the drive coupling, Primary Clutch Disc, or the cotter pin may have managed to fall out of the drive coupling.....I would remover a side inspection door and check the drive coupling first...

It's a long shot...however when the, primary Disc failed...the PTO was still functioning properly on my MF 35.....

NON of the GEARS in the TRNSMISSION were operating.. there was no POWER from the ENGINE being transmitted to the GEAR TRAIN..

REMOVE a side inspection door and view the coupling components..

Ok. I found out that there was a "pop" or clunk that sounded when the clutch was let out and it didn't move. The sound was described as coming from under the seat.... Cotter pin in drive coupling broken?

Remove inspection door / doors and view Coupling.....

To the best of my knowledge you shall have to drain some oil ...Oil sump is a common sump, as in Transmission, Hyd, Differential.

Drain oil below bolt hole circled on inspection plate...
