So ive got a 2007 50inch Cub Cadet zero turn with what appears to be a transmission problem. The right side works sometimes and sometimes doesnt. it seams like after the mower has sat for a while it works fine for about 10-15 minutes and then starts acting up. sometimes no reverse on it and other times barely any forward. It does appear there is a small leak from one of the seals on it which i plan to replace very soon but i keep the fluid full even with the leak. i was wondering if bc of the leak it could be causing air to get in adn creating an air pocket? it also makes a weird noise when its not working correctly. any ideas? could it be maybe an internal pump thats gone bad? im trying to figure this out because when i crack the case to replace all the seals i would like to replace the possible faulty part as well if thats whats causing this issue. please any help is greatly appreciated!!!!!
