I don't have a ton of experience with the AH tractors, but I've had a few of them over the years. Currently I have a 4118, the tractor runs great, drives great, and does a fantastic job with the hydraulic snowblower, but the hydraulic 48" deck wants to stall the tractor when the PTO is engaged. All spindles are free, motor turns by hand, but really wants to bog the tractor down when using the tractor power/PTO. Is there something that I am missing, or does anyone have any tips or ideas? Thanks in advance.
