I volunteered my brothers New Holland, 5 ft. rototiller to smooth out an old plowed field. My brother decided to use it with his WD45, so that if anything broke, it would be his fault, not mine. After about 15 minutes of work, something popped. I was sure it would be a shear pin some where on the unit.Oh no! It snapped the shaft,on the drive side,just inside the left side bearing. The main shaft that all the blades attach to. You probably could not have cut it any straighter than what That break is. This unit is six years old and has almost all the paint on it. The blades are not beat up at all. The sod had been broken up with a disc the night before. Why did it break? Would the depth of cut and to fast of ground speed be the reason for it? Don't they usually protect these tpyes of equipment with shear pins? Shouldn't there be a shear pin on the PTO shaft, that would break before that shaft did? Don had not ever broken anything on this tiller before today. Can it be repaired, or is the only option a new shaft?
Thank you SDE
