jd 777 zero turn has little power on right side drive wheel

[turnkey47]

have a john deere 777 zero tun mower with bagging system and when the mower gets hot there is very little power to the right side drive wheel..also the right side lever when pushed or pulled is way in front of the left side lever...feels like there is no pressure on this lever..fluid in the tank is full....does this sound like a bad drive wheel motor????

same problem here on a 777 Z-trak with only 335 hours (used residentially). Wish I had researched more. Sad to now hear about all the Kanzaki DUP-13 pump chips & machining burrs taking out Parker TF0240 hydro motors. Right motor gets more direction flow change given right discharge chute location (CCW around trees) as evidenced by tire wear. To isolate issue, need to test with a Hydraulic flow & pressure meter to see if pump produces at least 1.5 gpm @ 300 psi. If less flow replace pump, if more replace motor. Almost as frustrating as my hydro pump failing at less than 350 hours is to see the price mark-up that Deere charges on third-party parts....double the price.

Kinda reminds me of what they do when selling their tractors too.

Excellent solution, I am sure this will get these guys up and mowing in no time
