Hello to everyone, I am new to this forum and hoping to see about parts for my old W5021 SC walk behind mower. My Dad bought it new in 1989, it still starts and runs like a champ (no surprise there) but the clutch is binding up terribly. It takes a very slow, sensitive motion to get the blade to engage without stalling the motor because of the extra binding pressure of the clutch plate. I purchased a Troybilt walk behind a year ago because the Kubota is not efficient in its operation as outlined above. The Troybilt is fine, does what I need (I don't do much handmowing, most of what I've got can be done with the ride-on machines), but I haven't given up on getting the Kubota back up to spec, now just for nostalgia I can't find any parts for it, not Ebay, not standard internet search, contacted multiple dealers for the possibility of NOS parts gathering dust on their shelves--nothing. Any hope for this old but strong running machine? Thanks
