Zero turn steering issue

[cigar1]

My Zd18 will go to the left when I push both bars full forward. I don't see anything in the service manual which addresses this issue. Any help would be appreciated!

There is a adjustment for the travel of the pumps. Not to unusual to have to adjust as the pumps and linkages wear. There are also adjustable stops for the control arms as well as centering adjustments.

If it is really pronounced, and the adjustment does nothing to correct it, then that would indicated that the one pump is getting weak. Not much to correct that other than replacement. You might check and see if your model was one of the ones that had pump / reservoir issues.

Or the tire pressure is way off from side to side as that will affect the rolling resistance and diameter.

Thanks, the tire pressure is good I check it about once a month. I will read up in the service manuals to see how to make adjustments. I'm not sure how to go about checking to see if it was one with a pump / reservoir issue. I bought it last year with about 1900 hours on it. Other than this and a couple of minor things it has been really great, a horse.

Im guessing this is a hydrostatic type transmission, both pumps should sound the same,possibly one is louder than the other?

I have seen peerless hydros fail with less than 500 hours. Dont know what kubota sells them for, but peerles run around 1200.

You should check with your Kubota dealer. There was a issue in that on side hills, the uphill pump would cavitate and be damaged. A new reservoir and pumps were brought out to correct this.

Never showed up on flat ground.

Hopefully though it will be just a adjustment!
