Well here is the latest. I took off the hyd. motor. With the hoses connected together and the other end still going into the hyd. motor I can turn it by hand very easily. It was the same way when it was hooked to the 425. It was very easy to turn by hand. To me this doesn't seem right.

A little more history. This attachment was only used a half dozen times, then sat outside for at least 5 years. Could this have caused any of the problems that I am having. In case I didn't mention it, the pt with pt attachments works fine, so it makes me believe that the problem is the aeravator.

Some hydraulic motors will turn by hand with little effort. There are many kinds of hyd motors, gear motors, vane motors, piston motors, etc. On my PT, if I raise the PT off the ground, and I turn one wheel by hand, the other wheel will turn .

Let me offer some good advise. Since you own a machine that is all hydraulic, educate yourself well in hydraulics, so that people will not take advantage of you, and you will be able to fix just about anything hydraulic. I still don't know all that I want to know.

Does the areavator turn easy without the motor attached?

Yes it does turn easily.

Your motor is probably leaking internally, or bypassing, which means that you can not build up enough pressure to operate the hydraulic motor in the manner which it was designed. If you need a new motor, check out Surplus hydraulics, or some other discount hydraulic places. The local hydraulic distributor will ask big bucks for their motors.

Here is an update. The motor was bad. I took it to a tractor repair place by me. They said it had some frozen parts inside. I looked at it and some of the parts I couldn't even move it with pliers. So my guy went to ordered a rebuild kit. White said they don't sell rebuild kits for this motor, just seal kits and whole motors. So after all of this I ended up ordering a new motor anyway.

If I had known you couldn't get a rebuild kit I would have ordered a new motor weeks ago instead of all this messing around I did due to my busy scedule. So it is fixed as of this past monday.
By the way the thing works great. When I walk across the lawn from one section that hasn't been aeravated to one that has, it is amazing the difference. You can feel how soft the ground is and it doesn't even disturb the grass!
