Hello! I have a Country Clipper SR350 and the left transaxle has went bad. T seals were replaced and I was told by a certified mechanic that everything else looked fine, but once the mower is warmed up it stops functioning. The part number is Hydro Gear D3763-02 (appears to be from their 310-2600 line up). This is now discontinued and I can only find one refurbished unit on the web for $850. Does anyone know if I can upgrade this to a newer Hyrdo Gear model of transaxles? Or does anyone by chance know of other mowers that used these exact same transaxles that I could maybe find at a junkyard? My knowledge is limited in the driveline category where I don't know if the linkages would line up or if it would require a new shaft, etc? Thank you all for any input!
