Cub Cadet 122 - Doesn't Move Except with Slight Pressure on Pedal

[GreenAcre]

I have a '67 Cub Cadet 122 with manual transmission, no creeper gear. I was hauling a heavy load up a hill last year and thought I burned up the clutch -- it quit pulling and acted like it got put into neutral. Could shift between gears with engine running with no movement. I parked the tractor until this past week when I replaced the clutch with a new one. Well guess what... still doesn't move.
*except*
If you put ever so slight pressure on the pedal it will try to move and sometimes drive on flat ground!!

I adjusted the clutch and brake linkages as the manual stated with no improvement.

I noticed the driveshaft has some forward/back play in it (about 1/2 inch max). Is this normal?

I'm at a loss on what to check next, any help would be greatly appreciated!

Here's a video link (to the end of my video) where you can see the pedal/walking that it does: https://youtu.be/D_HFIeqt0PE?t=1318 The video was shot before I adjusted the pedal, but the performance is the same.

Thanks guys,
Sam

Something is grossly wrong with your Clutch and/or Linkage.

Was just about to say same thing.. Got any pics of the clutch and linkage?? The pedal travel is definitely not right

I can get photos of it tomorrow, sure. Maybe something holding the springs in place broke? Glad I didn't put the grille back on yet since I'll likely be pulling the clutch assembly out.

Here's some photos of the assembly in place.

Check for a broken spirol pin at the transmission coupling.

I'm going to say Delta Cub nailed it. I took your picture and marked it up. The red arrows are the spirol pins. They "SHOULD" be in line as by the white line I put on the driveshaft. the transmission coupler is turn down about 15*

I make driveshafts and make sure the holes are all in line. The factory made them this way too.

Agreed.... If you're in gear with foot off the clutch and you see the shaft spinning but you're not moving..... You get the picture?

[GreenAcre]

Ahh... I would have never noticed that! Is this possibly replaceable without splitting the tractor, or is that the best method?

I have a creeper gear that is supposed to be complete that I thought of putting on this at the same time if this issue lead me down splitting the tractor. But I'm not sure of adding more unknown parts to the mix either.

You can replace the spirol pin without splitting the tractor. Wear eye protection. If, however, you want to add the creeper drive you will need to split the tractor. Since the driveshaft needs modified or changed, I would order a new shaft and coupling from Jeff In PA. His replacement parts are top quality.
