Simplicity prestige no power steering or hydraulic lift

Recommended Posts

I have a simplicity prestige with no power steering or hydraulic lift. It was working fine with no problems and I put a trickle charger on it for two days. I started it after taking off the trickle charger and that’s when I had no power steering or lift. Did putting the trickle charger on cause this problem and if so what am I looking at or do I have something else going on.

I don't know the Prestige, but I doubt the trickle charger has anything to do with your problem which is most likely hydraulic.  Is there a hydraulic "disconnect" you might have accidentally engaged?   

I'm not familiar with the plumbing on the Prestige, but on a Sovereign, if you lose the "high pressure" hydraulic circuit, PS and lift will be affected.  Might be the same on a Prestige.  A "staying open" high pressure relief valve at the charge pump or another pressure regulating component (in the hydraulic lift valve) would do this on a Sovereign.

The key information needed here is:

Does the tractor move in both directions(forward and reverse) as normal?

If not, then its probably either the push release rod is pulled out as Bill hints to, or as Ron suggests, the drive belt has come off or is broken.

If i does drive as normal, then the problem is likely with the hydraulic circuit.  Oil goes from the transmission out to the power steering first,  then to the hydraulic lift, then dumps back into the transmission. There is also a spin on hydraulic filter in that mix too. Could be a problem with any of those components preventing the oil from circulating. There is also an oil expansion tank thats supposed to have a certain amount of oil showing in it.

If the spin on filter hasnt been changed in several hundred hours, you could try that. However I think it would be wishful thinking that that would fix the problem. But its a start.

Most of the Prestige complaintas( other than engine related) I am aware of deal with the power steering unit. If I had to guess, I would probably suspect that. In fact, One of my Prestiges works in every way, but the power steering is alsmost as bad a manual steering. I changed the filter, checked all the linkages, and disassembled and cleaned the steering wheel assembly. Nothing helped. The high cost of a replcement part has so far kept me from proceeding any farther. Till it takes 2 hands to steer, I'll just ignore it for now.

I’m at that point now it definitely takes 2 hands to steer. I am still amazed at how it was working fine with absolutely no problems when I parked it and 2 days later the power steering was gone and the lift working very, very, slow. Just wondered if anybody else has had this problem or if anybody out there can possibly explain this. Thanks

I'm having a similar problem with my Landlord DLX which uses the same steering torque generator and transmission as most of the Prestige tractors. The lift seems to work OK but the power steering feels tighter than manual steering . I changed the fluid and both filters. No change. The hydro is a bit louder than it used to be, especially in cold weather.

On my Landlord its just supposed to be a tank for expansion when hot. Most of the time there would be little or none in it. Your tractor may be different. The operator's manual will explain the transmission fluid filling/checking process.

Well guys I bit the bullet took it into the shop after working on it myself they are telling me I need a new transmission does this sound reasonable to anyone out there

It may be this is necessary, but did they explain why and what did they do for tests and diagnostics to come to this conclusion?

I too also wonder how they reached that conclusion, especially as the machine still drives properly. 

Me too. I would want a detailed explanation as to why they think it needs replaced.

If the transmission is pulling the tractor around up hills and all around in both directions, cant hardly believe it would be the problem. Only way I'd even consider to pay the whoppin 4 digit figure to replace that would be that if it did not fix the problem that they would refund your money in total....and get that in writing..

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
