When in gear, Tractor will not move

[JD5210]

I am unclear what line you replaced, it sounds like you replaced the line from the SCV. Do you have a part number and I can look it up on JDparts. The seat switch does nothing, but sound an alarm if the PTO is on and you leave the seat. Once started there is no safety switches which keeps you from going. I take it acts the same no matter what range/gear you are in. Here is a link to tractordata, if you look at the bottom left you can match serial number to your tractor. Here is a picture of the hydraulic system. Does the steering still work?

What you replaced should not keep it from moving.

Apparently, air got in the system and had to bleed off. I worked the bucket a few times and put it back in gear. It moved. Thanks to all for your help. It appaears all right now.

Strange that a gear drive transmission which should only use Hydraulics for lube and cooling failed due to air in a Hydraulic line. If it was an HST, I would have said continue cycling the Hydraulic cylinders to remove air.

Since my last post, I have heard that air in the hydraulic line is a possible cause, it is more likely that it is a faulty cut-off switch under the seat. Thanks for your input.

Agreed. Too much dependent on hydraulics. Could it be a safety feature to assure it isnt run low on hyd/trans fluid?

Is the engine started and running when you put it in gear. Honestly it sounds like it's something simple like that. Did you leave the park brake on etc? I'll give you an example. I recently threw my jacket behind the seat of my JD 4410 compact utility, got on and started it but it wouldn't move at all (ehydro model). The tractor had just been running so I knew it had to be something simple. The simple act of throwing the jacket behind the seat disconnected the plug for the tractor seat safety switch enough so that there was no connection. In less than a minute I was going again. Tell us the model and year of tractor. It's pretty hard to tell you anything if we don't know what you are talking about
