Model 1330 Hydrostatic Transmission problem

[glomarexplorer]

Help!!!!

Just got done last week bringing tractor out of mothball, and was ready to have it moved to new home so I could cut grass, since I already have mowing service in current home. Everything was working very fine.

Contracted local lawn repair guy to move tractor. He really didn't seem to know how to operate hydrostatic system and engaged dump valve while trying to push speed lever forward. He had already moved back tractor about 10 feet, when he exercised same maneuver, at which time transmission made some noise and could no longer be engaged.

Belt works; dump valve works with engine shut down, and would allow tractor to be moved when disengaging pump. Tractor is in like new conditions otherwise.

Can anybody offer any advise? Also, how do I find transmission and pump assembly manufacturer and part number? Local Cub dealer wants >$200 for diagnostic-is it worth it? where could I find re-built unit?

Please help.

Welcome to OCC
What do you mean by, "noise and could no longer be engaged"?
Having the "dump" engaged and moving the speed selector isn't going to kill the tractor. If your talking that the speed selector can't be moved, take the brake off because that's the only thing that will stop it from moving.
More information needed!!!

Zippy1,

Thanksfor replying.

Breakes donn't seem to be on. Tractor can be moved by hand by engaging dump pump. With pump disengaged, tractor cannot be moved at all, so that aspect of the system is working.

Drive belt seems a bit stretched, but everything was working fine just before all of the bad shifting by technician, who also tried to shif, forcefully, with breaks on. Is there some "interrupt" switch which is somehow left in "open" position, or could the dump valve be stuck in open position somehow.

Please advise.

Thank you.

BTW, speed selector lever operates fine, but transmission doesn't seem to engage at all and tractor doesn't move. Could it be possible that there is a "stuck open" sensor somehow which prevents transmission from engaging? Also, could it be possible that dump valve is in "stuck open" position?

I'd suspect that any broken shafts or gear would result in significant mechanical noise, which I am not presently experiencing.

I am contemplating installing new drive belt to eliminate sagging/stretch as possibility, since I can easily soin the two sections together near tensioner pulley; however, one would expect that there is sufficient pressure/contact for the tranny to at least try to move the wheels.

Please advise.

Thank you.

I suppose it could be a belt issue. Only time mine stopped is when I blew a belt, never heard of one stretching enough to stop the drive, but guess it could happen.
There is no sensor that I'm aware of that would stop the tractor from moving, so that wouldn't be a issue. Could be a valve I guess. Could it be that the dump lever got bent somehow and is not disengaging completely?

Yeah,

That seems possible....dump valve could be stuck in open position. I'd hate changing drive belt, being that it is so laborious and cumbersome, but I'll try it, nevertheless.

BTW, do you know complete transmission and pump assembly P/N for this tractor? I am trying to get a re-built or used one, so I could get it running, re-build the present one. Also, is there a site where overall tractor service manual could be downloaded from? I 'd also like transmission diagram and part numbers, etc.

this is just so bad, because my tractor really looks in "showroom" condition; also, engine runs like new.

Please advise.

Thank you.

Here is from parts tree

A new trans is going to cost you mega bucks, this was discussed before on here. The tractor isn't worth the money, regardless of it's overall condition.
I would just check those things mentioned earlier and see if you get lucky enough to find something simple.
