Jack it up and try turning the rear wheels. IF one turns harder than the other you've at least isolated the problem. I doubt if ice is your problem. The hydraulics would warm up the fluid and melt any ice in there. [Reply]   [No Email]

A bit of an update, and thanks for hanging in there with me. I put it in neutral this morning and tried to push, but alas at 165 pounds I am little match for a ton tractor to make a real test of it in the shed. So I started it up and backed it up a bit (no problems at all) and then let it roll forward in neutral about 5 feet. That worked. I jacked the back end up and when in neutral I couldn"t turn either wheel. Not sure if I was doing something wrong or not, but it also seems like a lot of gears to turn by hand so can"t answer whether on wheel turns harder than another ???? But here is something new I discovered as I looked at the brake mechanism. First off, the seals all look good around the linkages. But when I push the brake down there is no give (and when moving forward little braking action)-- push pedal ... no movement of anything to actually "brake". But when I decouple the brake pedal (there is a bar that connects the right and left pedals so they go down together) the left pedal - presumably for the left rear wheel brake appears to work normally (push the pedal and it moves -- tho what "normal" means is a guess since I have never looked at it before) while the right pedal - presumably for the right rear wheel won"t budge. It makes me think that if a brake is stuck it might be that one. Make sense? Now -- how does one "unstick" a brake? And why if the brake is stuck on can I back up or move in a normal manner at all? Thanks for your brains on this one. [Reply]  [No Email]

If one pedal is rigid, and does not move, it could be that the brake cylinder is mis adjusted and not allowing the pressure to be released. The piston in the master cylinder for that brake must retract all the way to the limit of the bore. if it doesn"t. or if the cup is swelled up covering the compensating port, the brake will stay on. If both wheels are in the air, and the engine is off and the trans is in any gear, one tire should spin forward moving the other backward (differential) easily. If not, there is an issue with either brakes (I hope because it is easy) or a bearing, Jim [Reply]  [No Email]

Weather hasn't warmed up (-25 this morning) but today I jacked up the back end and the back wheels turn pretty easily, except at one point they get significantly tougher to turn. The resistance lasts about 1/4 or less of a turn, then gets easier again. No noticeable difference between tires turning. The seals on the brake cylinders are intact, although as I said earlier when I disengage the bar that connects the two brake pedals the left pedal has play and the right one doesn't move at all. Does this help at all with the diagnosis? If the brake cylinder was frozen would the wheels turn? Thanks. Erik [Reply]  [No Email]

Out of town for a few days but will try when I get back with what I find. Thanks for your help. Erik [Reply]  [No Email]

I will check that out tomorrow morning. It felt like it wouldn't roll in neutral, but I didn't put a real shoulder into it either. Why would it appear to work fine with the fresh hy-tran fluid for a brief time, and then seize up again if it were a hung up brake or seized bearing? Could those be intermittent? I will post what I find out. [Reply]  [No Email]

Sevier damage can result to the housings or case if allowed to be operated as is. Jim [Reply]  [No Email]

Going out to check what I can find (unfortunately the temp dropped to -15 so it"ll be a bit chillier. Question about the bearings if it is a bearing. Best thoughts on which one?: The mainshaft bearing, differential bearings or in the wheel assembly/hub itself? Probably any of those is outside my league since I don"t have the equipment to lift or pull that large. Thanks again for all the help. [Reply]  [No Email]
