Weak reverse on Scag WB

[Aaron's Lawn Care]

I bought an '02 61" Scag WB with the advantage deck bakck in the beginning of the summer. The mower has been great with the exception of having a really weak reverse. I had another 61" Scag WB before this one and it had a really strong reverse and it was a 1998 model.

At first, both wheels had a weak reverse but then I had my guy adjust the tracking and raise the handle bars for me (I'm a tall guy) and that fixed the problem on one wheel. Now I have one wheel that pulls strong in reverse and another that is really slow. The weak wheel seems to be getting weaker and weaker the more I use it.

Does anyone have any ideas for me to fix this? Could it be the hydros themselves? Maybe the wheel motors?

It could be either 1 of the 2. Maybe also the adjusting rod is loose and moving from vibration. thats what was wrong with my Z. I was tinkering with it 1 day and forgot to tighten one of the bolts.

Thanks for the help. Anyone else have any ideas?

Sounds like your guy needs to re-adjust the weak side, He is probably too far forward on the neutral band.

but when i let it go without touching the controls it rolls perfectly straight. wouldn't it be pulling to one side if it wasn't adjusted correctly?
