How to Fix John Deere 4720 Tractor Seat: Adjustable Pneumatic

This is a narrow, practical repair video for a specific complaint: a John Deere 4720 pneumatic seat that won't go up or down. The creator pulls the seat cushion, shows the air pump and switch, and diagnoses a common cause - a red wire that gets pinched and cut between the pump body and frame, sometimes blowing the seat's air pump fuse. He demonstrates splicing and weatherproofing the wire. Best for owners diagnosing this exact seat issue, not general tractor shoppers.
