Snapper Hydro Drive

I'm not sure this is the best forum or part of this website to post this question, but here goes. My son-in-law has a Snapper Yard Cruiser Hydro Drive, Series 2, that I have tried to help him with as it's unknown to both of us. It basically operates fine, but we can't get it to let itself be rolled. The lever for that purpose doesn't seem to do anything but I can't tell that anything is broken or disconnected. Anybody know about these things?

pull the release and rock it mine would not roll and I kept on till it got freed up it is a valve I think that just lets the oil dump so you can push or tow it

IF clutch/brake pedal has a mech latch to hold pedal in depressed position(down) when tractor parked,release latch & pedal,the trans has an ext brake disk with a caliper,in normal operation when running tractor,brake caliper is applied against brake disk when pedal depressed to slow/stop tractor,when pedal locked down brake now serves as a parking brake & locks trans.

This one has a brake lever, but it doesn't seem to be the problem. The mower drives okay, and the brake lever seems to release okay--it just can't be rolled manually and when it's on jacks the two wheels can't be turned. I'll try forcing the wheels to turn, but somewhere I read there are "pins" where the release levers are hinged to the hydro units that stick--anyone know more about that?

The pins you are refering to may be the guide pins on disk brake caliper,these tend to stick in caliper body due to rust/dirt and as the pads wear the pin travel required to apply brakes is longer,if pins rusty/dirty caliper may not release completely or not at all.Looking at assembly drawings of some mod snapper tractors the brake locks one of the reduction gears in axle,if brake not releasing completely due to sticking caliper/parking brake engaged,rear wheels won't turn when both off ground.

Goto link below & click on snapper logo,select mod# from tractor list,look at transmission group & clutch/brake assembly drawings,may help you find out what's frozen,broken or disconnected in linkages or brake system.

I have the same manual and parts breakdown as this site shows. It really doesn't show what I need to see. I am under the impression the brakes are inside the two hydro-drive gearboxes. Can't see any disc brakes that I can tell.

Due to fact you didn't include mod# of tractor,I just went to partstree & looked at assembly drawings/parts list for several mod# hydro drive series 2 tractors,if you have assembly drawings/parts list for tractor,look at transmission service parts drawing & look at items 12-16,this is the brake disk/caliper assembly,if you don't have a drawing/parts list for above parts or can't find on drawings POST MOD# of tractor so parts list can be looked at online.

Mine is Snapper Yard Cruiser Hydro Drive HZS15423KVE. My book doesn't show any parts breakdown for the transmission internals. I'd sure be interested to find some.

OK-I went back to partstree & looked at mower,I orginally looked at series 2 lawn/garden tractors,your's is a zero turn mower which has a completely different transaxle,if both brake rods are releaseing I would say problem lies in freewheel valve as ronnie said,possibly due to a sticking/dirty valve or possibly cable stiff/rusty to valve arm & not pulling arm on valve far enough to release hyd fluid in trans,the brakes are probably a hyd function within trans,there is no ext disk brake on trans as used on lawn/garden tractors.

Thanks, Joe. I've looked all over and can't find any parts breakdown for the hydro units themselves. Have found some other repair manuals on ebay for other hydro units. These are made by Eaton. I will explore the sticking valve idea, the cable and the levers it attaches to seem to be quite free.

click link below for diagram.

#26 is the lever on the transmission that lets the mower move. Appears to be on the bottom of the hydro trans. Might have bent it.

#40 is the cable that pulls that lever.

Make sure the E brake is off when trying to roll it. You might need to hold the trans release knob while rolling it. It might not hold itself.

They are two different hydro transmissions. From the diagram, I can only see one release lever but each trans might have a release lever on it.

I appreciate the suggestions and taking the time to hunt for the diagrams etc. What it turns out is, there is a lever on each Hydro unit that releases the hydraulic pressure; they are linked to a common release cable. All of that is undamaged and free. The levers each bear on a sort of rod that goes into the case and apparently press on a valve inside. Those rods don't pop out like they should, and yet, they don't appear to be frozen. So either something inside isn't moving like it should to pop them out, or--maybe--there's not enough oil in the case anymore to develop the hydraulic pressure to move them. It seems to be impossible to add oil, at least, the manual says to take it to a dealer. That may turn out to be all I can do.
