need some help, i have a sub compact kubota bx24 i use a king cutter tiller last season i tilled a lot of gardens winter came and i stored tiller next season i reinstalled tiller to start season and when i engaged pto it wouldnt work, well i have exhausted all trouble shooting to repair this problem but with no success . i am not even sure how pto works on my tractor , thinking it was a linkage problem i removed pto clutch handle and found that all this handle does is open and close a saftey switch? no actual linkage shifting pto ??? any help or advice welcomed or has anyone else experienced this problem , i talked with mechanic at kubota dealer and he had never heard of this and insisted there has to be some kind of linkage connected to pto clutch lever so i am just baffled help please
