 Can you feel the end-play or see it ??  would the rear wheels feel sloppy or how would I know if it needs adjustment.??

  

 

A gap may be visible as Brian said.  ....I have seen transaxles that were so loose that the tractor could be pushed with the wheel-lock pin engaged.  ...Other times a tractor might drive OK on flat ground, but would not climb a slope or move under load. 

 

If axle end-play is neglected too long, some expensive parts can be damaged!

The previous owner had it right, he said he had broken the rear end.  I raised the tractor and pulled on the wheel and off it came.  Good or bad, pretty easy diagnosis even for an average dude like me.  This is a pic of the right wheel and axle, sheered right of.  Looks like it broke where a pin inserted.  I am sure the pic will make sense to anyone who has worked on these.

Yikes!

In that case your better off just swapping out tranny's and using this one as parts. This would require a rebuild to replace that shaft.

I had one break on my 850 as well a few years ago.... Maybe there were a few defective shafts that made their way out of the factory?

The previous owner said he inherited it with the farm house he bought from the original owner,  He said he was mowing at a good clip, hit a bump, and that was it.  It is a super nice original that still had the original seat nice and intact.  He seemed to be remorseful for killing it.  I assured him I would give it a second chance at life.

 

Thanks to all

Tim

It's possible something is broken, or just the rear-axle end-play needs to be adjusted. 

 

Correct rear-axle end-play is important on these tube-frames.  ....It is very easy to adjust.

Bruce.. And other EXPERTS.. I copied the end-play instructions took it out to the tractor,,Now did the PO change something ?  There are self-locking torque lock nuts on the wheel shaft.. Not the castle-nut and cotter key.. I'm going to try and adjust the axle adjust end play with those nuts..But did some years have a different setup with the nuts I discribed ??

Its been about 5-6 years since I worked on one of the Hydrostatic tubeframes so I cannot recall if the hydros had the same lock nut configuration.

 

After looking at the partslist, the Hydrostatic Models did indeed have just a plain nut without a cotter pin.

I would assume these are of the Nylock type that you would just turn in to adjust.

I believe the link I posted was for the procedure to adjust the end-play on gear-drive tractors.  .....I never  adjusted a transaxle on a hydrostat model, so I'm not sure if the procedure is the same.

 

There should be info in the Tube-Frame Service Manual posted in the manuals forum, but I didn't check.  http://gardentractor...anual-552875-1/
