Hydro drive problems fast track mini

[Geebourque]

I have a fast track mini 42”. The left side hydro drive is not responding well. It still operates but lags and sticks when turning. Any advice?

Had similar problem drained fluid ( 15-- 50 Mobil 1 synthetic oil) replaced filters and make sure to properly bleed air out of system. Read up on correct procedure

I have an SD 60 and found a bypass inside was leaking. I wrote about it here. It works awesome now.
