I have a, '03 x475 (AWS) and it has a peculiar issue of not wanting to move. I drove it off a trailer but a 1/2 hour later the forward and reverse petals are hard to push and I get a whine when I force it. It seems like the brake is still on but it has been released. Additionally, I tried to move the lever by the transmission into the 'freewheel' position so that it will roll, and it does not want to go all the way up and the tractor will not roll. The hydraulic fluid level is correct. Any ideas?

Here is a diagram of the brakes:

I know you said the fluid level was "correct", but what about its condition? Clean/clear or dark/milky/foamy looking?

you guys are awesome!

Here is a diagram of the brakes:

You even provide schematics! It is very very cold up here with a high of 4 degrees today! I could use a little tarheel heat right now. The brake is what I suspected but I couldn't find anything wrong, however with the schematics I can take another look at it.

The hydro fluid is darker but mostly clear, not foamy and does not smell burnt.

Maybe try to "gently" warm up the brake system, with a hair dryer or one of those hot air-forced salamander heaters positioned far back enough to not melt or catch anything on fire?
If it "rolled off the trailer" and set there a while, it leads me to hypothesize that the brake was applied after removal from the trailer and set there overnight, eh?

What kind of hydro oil is in it? If it is really cold out and this is sitting outside, the oil just might be stiff until you get it to warm up.

Additional details

It wasn't this cold when I drove it off my trailer...probably in the mid thirties. I drove it off the trailer and parked it for 30 min. or so, then went to move it and it wouldn't budge.

JD Hy-vis or whatever JD hydro oil product is in it.

I let the tractor run yesterday for 30 minutes to warm up with no benefit.

I did jack it up yesterday to put the rear wheels on dollies so I can move it around my barn and they only have an inch or two of play. Does that mean it wouldn't be the brake?

The deck lift does work, if that is a clue.

Thanks again y'all for the brainstorming.

I'm almost thinking you might have some condensation trapped in a system, and has it "frozen-up".
Does that sound plausible?

My vote is for locked brakes. Could be frozen. It is that time of year. Otherwise, could be a malfunction in the brake system. Of course, you did check to make sure the parking brake is off??? You may have already mentioned that, but my memory does not go back that far.

The fix is in!

OK gentlemen, due to facts and the responses I highly suspected the fix was simple regarding the brakes but following the brake system I couldn't figure out what it was. I trailered the tractor ( in 7 degree weather with whiteout snow conditions ) to the local JD dealer to take a quick look since he sees 20 of the units a day and he quickly determined it was a faulty brake release switch. no charge. I have an irrational attachment to high quality equipment and wanted to take care of this right away.

Thanks everyone for your input!

Thanks for the follow up. I suspected (as many others) that the brakes where hanging up somehow, I had hoped posting the diagrams would have helped you figure it out. Kudos to your dealer :good2:
