I am replacing the pto shaft on a 38HP tractor (Antonio Carraro) driving a 60" flail mower. The current shaft "bottoms out" when I raise the implement, causing damage to the lock groove in the splines. According to my measurements, I need 3 1/2" of telescoping ability on the shaft to avoid the problem. This is not an extreme amount of travel, however the shaft is quite short. If I cut down the replacement shaft to work, it will have only 3-4" of contact between the two shaft halves when in working position.
Is this advisable? Any suggestions? (The lift arm holes in the mower have already been extended to move the implement farther from the tractor. There is no toplink used, as the lift arms raise the whole mower deck.)
