    I doubt you can find an actual repair manual. I know what's involved removing and replacing the hydrostatic pump and you basically have to learn how to do it yourself (if you're mechanically inclined and have patience). I had nobody helping me at all from start to finish so it can be done by one...

    Make sure to replace any rubber 0-rings where the hoses attach. On mine some of the leaks were from bad 0-rings but not the hoses.

    Those hose leaks can sometimes make it appear something else is leaking. That's why it's important to pressure wash everything so the true source of the leak can be found.

    I rarely have to use the brake since the machine stops automatically when taking my foot off the pedal (like a lawnmower does). However, that's only when it's used on flat terrain. Tt's not a positive stop, so it will try to roll on an incline due to the weight of the machine. As far as the...

    My serial# is 211. The axles have "79" stamped on them. It doesn't have a foot control brake, only a hand brake. The others I've seen have a foot brake. Your machine looks like it's been well taken care of its entire life. My machine had to be brought back from the dead. The engine itself was...

    Yours is slightly older than mine. I not sure but I think 1979 was the first year these machines started production. Mine is also 1979. I use it a lot but only on my farm. I don't let anyone else use it because I don't want it abused. These machines can be dangerous because of lack of safety...

    Sure isn't fun no matter how it's removed. It's a learning curve for sure. I opted to remove the fluid tank and side panels to give myself more room to get the pump removed.

    I know this post is old, but I was confused if you were talking about the hydraulic pump or hydrostatic pump. Both are labor intensive and time consuming. And no, the engine doesn't have to be removed to fix the hydrostatic pump. Just the hydraulic tank. Figuring out how to remove those side...

    In case you still have your machine, the parts come from different vendors. Let me know which parts you need and I can help you find the vendor for the specific parts. Some of the parts are rebuildable at local hydraulic shops.

    When a machine gets this old it's best to just put it out of service for a year and begin replacing everything to bring it back to reliable working condition. That's what I did. So now when I use mine, I don't have to work on it every time I use it. I spent around $8,500 dollars refurbishing...

    On mine the wheel base is 53" center to center and 66" outside measurement. These machines weigh 6600 pounds so with other attachments on it I would use a trailer rated at no less than 12000 lbs.

    In the earlier post I mentioned looking for a service /parts manual on e-bay. Type "Prime Mover LD-50" instead of "John Deere LD-50"

    I use Shell HD universal tractor fluid. It can be purchased at Tractor Supply. Given the age if your machine I would recommend cleaning out the strainer on the tank as well. It's up to you. Also replace the rubber high pressure hose that connects to it. The hydrostatic pump located under the...

    These machines came with 3 different engines. The 4 cylinder Continental 2.7L gas engine, the Deutz 2.8L diesel, and the John Deere 3164 or 3179 diesel. Mine has the John Deere. You can eventually find a service manual for the machine itself on e-bay if you keeping checking the site often. Just...
