Ferris zero not turning well

[alwaysridin]

I have a ferris 1000z zero mower. It does not turn well and the left rear wheel does not turn as fast as the right. I have adjusted the ground speed screw without success. My local mechanic could not find anything wrong.

Please post your model number, thanks. Also, have you replaced hydraulic filter recently & bled air from system per instructions in manual?

Thanks for the reply. Would the belt affect only one wheel turning? I thought the wheels were driven by hydraulics. Thanks. I will try to contact Messicks also.

It all depends upon where the tensioner is.
Most put them between the engine and the first pulley so one pulley has a bigger contact arc then the other.
This oft leads to one pulley not slipping at all and the other one slipping a little undr load.
This condition gets worse as the belt wears.
Check the routing very carefully, more than once I have gotten under a ZT mower to fing some one had reassembled the tensioner in the wrong place.
On a 61" Dane I ended up popping a second tensioner under the mower to cure the same problem.
However this is in general as I am not familiar with your machine and unless the mechanic is familiar, get a manual and check the belt routing your self.

Thanks. I will check this out. My mechanic did say that 2 spindles were wearing and I have purchased new ones, but have not installed them. I will check the tensioner and see if this helps.
