New to GT Talk...

I have an Ariens GT 20 with hydrolic steering that I purchased last Fall. The only issue that I have is with the hydrolic steering. At a dead stop (tractor not moving but running) the steering turns to the limit distance both left and right fine. But, while moving trying to mow in a straight line  I must continually turn the steering wheel in either direction to try to keep it on track and never reach the turning limit. in other words the steering wheel continues to turn. Any thoughts?

On an MM big tractor I had with power steering the wheel never returned to the same spot each time, so must be some "play" in them somehow. It DID stop and make that big whine when turned to each side tho. It also allowed turning but hard when tractor wasn't running.  I would bet some valve in the column unit is sticking?  If you have just a cylinder that pushes on standard linkages on axle, would think everything is in that box on steering column. Not much help here, but just what I have observed. Sure their must be manuals to buy/download or maybe need one for just the steering option as sometimes happens. Check the files here. Not sure if their is Arriens around any more. If is, try them for manuals on their site?  Might just check fluid levels and maybe change too for first try. Probly never been done in it's life.

Welcome to the forums!

I can't think of any one thing to look for. However, most of the components Ariens used were also used by other brands. 

 

Any Massey or John Deere guys with ideas?

:wave: Welcome to the forum! Sounds like it is bypassing fluid somewhere. Hope someone with more experience with these will chime in soon!

Kenny is spot on! Check your steering cylinder I think its bypassing the internal piston seals. Easy check ; turn your wheel in one direction only and at the end of the cylinders stroke remove the steering hose and see if oil comes out of the cylinder when you try turning it against the stop. If it comes out the hose your valve is bad, if it comes out the cylinder the packing on the piston is bad or the piston came off.

Boy, I wasn't expecting a response so soon. I'll give all suggestions a try. What is odd is that it only happens when the tractor is moving.

That could be a fluke related to taking the hydraulic flow from the hydro trans. I know on my much older S-16, lifting attachments will change between driving and at a stand still.

I have two Bolens GT2000's with hydraulic steering and they both do the same thing. At first it kind of bothered me that the steering wheel never returned to the same place but now I don't think about it. From what I have read it seems to be a pretty common phenomena and is probably why they don't use this type of steering on autos. Talked with people who own full sized tractors with this steering and they say it's a pain when going down the road.

I checked for leak-by at both fittings on the steering cylinders (good idea) and found nothing. Guess I learn to live with it seeing as how it doesn't take much to compensate for it.

:welcometogttalk:
Thinking the guys already nailed it, but is it possible the system is low on fluid and that could cause it?

One question I have is ; can you steer the machine when its not running? If not then you have a old designed steering valve ( no bIG deal you just need to compensate as you are doing now) the steeringvalve in my machine allows me to steer even if there is no oil flow .
I have no drift at all. If your steering valve is square and made up of a pile of thin plates it may be a drifter, as these are a rotary valves and dont have the ability to "pump" fluid like a gerotor style( more expesive).

Thanks for all of the suggestions! I looked through the manual and it appears that two of the hydrolic lines may be reversed. I know that the hoses have been disconnected at some point because according to the manual, my tractor model number and serial number never came with a 20 HP motor. Plus the motor model number is M20S. S for Simplicity. I'm reluctant to just reverse the two lines for fear of damaging the unit. But Ariens informed me that the diagram in their manual is correct s I guess I'll try it. A new steering unit is over $600.

Yeah, mine is a pain when on the road.
