Hello,
I’ve got a Kubota Z121S with 550 hours on it. I’ve used this unit to mow 1 acre with some slopes to it. Recently I’ve noticed a loud whining sound coming from the right side and lose power completely on that side when on slopes.

After seeing a rebuild kit for $50 I decided to just rebuild it and change both filters. The problem however didn’t get any better and am still losing all power on the right side when on slopes. Any thoughts? It’s been purged 3 times according to the manual. Thanks in advance
