I just got a new L2800 this week and when I have the PTO engaged driving the bush hog and push in the clutch there is a ratcheting sound that comes from the PTO that stops when I disengage the PTO. The dealer said it was normal as it some sort of free spinng that is a safety feature for the tranny.. but It sounds a lil nasty... Just wondering if all the 2800's do this??
