My 2015 XT1 only has 20 hours, sat in my garage (unheated) in NH for two years. My wife moved it around the garage a few times without engaging the hydrostatic transmission bypass valve.
Two months ago I discovered the Mower had a puddle of fluid under it along with a flat tire. I changed the oil, filter and added a new drain valve. Added a new air filter, added a fuel line shut off valve and charged the battery. It started up but doesn't go forward or reverse.
When I engage or disengage the bypass valve the mower moves easily in either position. I checked the belts ...seem fine. I spoke to a cub cadet technician he suggested checking the transmission seal? I have never been able to identify the fluid under the mower after sitting for two years. Not sure what other information needed to provide me with some advice...
