Is my Hydro pump going bad??

Hi,
I have a zero turn Turf Tiger. When I am running on flat surface it seems ok. When I put it in reverse the right side is sluggish. And when I come to hills going forward, I have the right stick totally front as far as it can go, & the left stick 1/4 way just to keep it straight. It moves VERY SLOW. It doesn't go as quick as when on flat surface. Any ideas what can be wrong? Is it the hydro pump? Can they be rebuilt?
Thanks!
Dan

First check the belt for looseness, Check the dump valves for being closed all the way. Then all linkage for wear/slop including the lever on the pump shaft. Check all hydro hose fittings for being tight, One could be sucking air but not leak oil.

i have a turf tiger that did the same thing. it was my right hydro. if i were you i would replace both hydro pumps and both wheel motors at the same time. and clean that resivor and hoses over and over and over and then clean them some more. trust me it will feel like a whole new mower. i know its a ton of money (around $2200) but your loosing money when you have to baby it all the time and move at a snails pace. not hard to do either about 3-4 hrs.

I notice when I'm done running the machine & park it overnight-when I take it out of the shed the next day, there is oil leaking on the floor. It's leaking at the tire on the right side -the side where the pump seems weak. I took the tire off, powerwashed everything really good but couldn't find the leak. Could that be the problem?
Thanks for the help!!

MOST defiantly, If oil can leak air can get sucked in. Air in the system means foamed oil which causes weak operation AND possible damage to pumps and wheel motors.

Find the leak and you will find your problem...if its by the wheel its either one of the hoses or the motor itself...

One more thing to check are your pullys. Make sure that they free wheel and the bearings aren't frozen up.
