Cub Cadet 127

I just bought a non running 127 with hydrostatic trans. I own 2 cub cadet 100s and am not familiar with the hydrostatic trans. I can't seem to get the trans in neutral to push the tractor around. It seems to be always in gear and the drivers side rear wheel won;t turn freely. I lift the handle on the right side that is supposed to allow it to freewheel, but nothing happens. Any ideas?

From my experiance on a 149, and a 1450 with hydrostatic transmission they are both in gear at all times regardless of what you do. Also it warns not to push/pull more than so many feet because of possible damage to the hydro

There should be a control lever you need to switch to the "N" position to move it...

There is a lever, actually a small rod coming out the top right side of the tunnel by the seat that when lifted will release the hytran pressure and allow you to move the tractor. I have a 127 and this lever doesn't work on mine.

I'll buy it if I were aloud (which I'm not) but any tractor is good for me babyg

I've got the lever, but no matter what position its in the left rear wheel still won't turn.

The left brake might be stuck.

If NEITHER wheel will turn, or one goes forward and one backwards when you try to roll it, the trans is shrapnel inside.

100,
If its like the wide frame tractors. There is a flat spring like thing that hooks to that lever. They will get weak or crack and not push down like they should to release the valves. But again these were only for a little push forward or reverse in the garage. Never very far. Just for your information NEVER EVER EVER tow one. Under its own power you will probly never have any trouble with a hydro. But towing them will distroy the hydro.

Thanks for all the replies. Once the rain stops I'll check out the lever and see if the spring is missing. I just need to push it a couple feet into the garage. I lifted the rear wheels and pulled it into the driveway with my 100, so the hydro should be good.

Just as Diz Jr. said the "flat spring like thing" may be bent, broken, weak or missing.

Another possibility is that all too often the relief valve buttons (the parts that the flat spring like thing pushes down on) get stuck from years of not being cleaned or used. The tunnels on the 1X6/7 tractors aren't removable and the relief valves are difficult to get at.

If it were mine I would take the transaxle out and clean it (like with a pressure washer or car wash) because IMHO the hydros run so much better when they are cool, and they run cooler when they are clean, I pull all of mine every couple of years or so and give them a good washing... However some of the other Guys disagree with me about washing them... We've been here before...

While you have it (the transaxle) out, check the valves to see if the butons move in and out. If not you will want to take them out and clean them up so they do work. While the transaxle is out check the lever (with the flat spring like thing) to see if its broken or if it works like it should.

Before you do all of that, I would get the motor running first, and make sure it's good.

If it has disk brakes and you think the left one is frozen, take the caliper off and see what's going on with it.

Once you get the left rear wheel to turn, if you aren't going very far with it, like just into the garrage, pick up one rear wheel and push it with three wheels on the ground, the rear tire that you have "raised" will turn backward, and moving it like this will not damage the hydro, because you aren't "pushing" any fluid through it.
