View Full Version : Hydro problem?

03-24-2009, 10:47 PM
I purchased an older Ransomes zero turn a few months ago to work on in my spare time. The mower had sat outside for a few years, but was running when parked with no problems. After alot of time and effort, the mower is running strong and has cleaned up nicely. The only problem is the left drive seems to be a little more dominant than the right. The left has to be backed off an inch or two to drive straight. Is this a major problem or can this be adjusted?

Make sure the bypass isnt slightly open. That can cause this very problem, but if thats not it there is an adjustment to calibrate the two together. First check the byass and if its loose just barely snug it do not over tighten, the reason its there is to allow movement of the machine should u need it to roll freely without pumping oil through the wheel motors.

If this is an old twintrack, take a good look at the transaxles/differentials. The lower part of the transaxle is the "differential" and may have leaked the oil out of it. You wouldn't notice any loss of hydrolic fluid. The pump and diff's are two different fluids. There are plugs on the diff's for checking the fluid level. One on the side and one on the bottom.
