While many older Ford tractors are still in service today, various accessories for these tractors are no longer available, including the Dowden foot feed. Red Rock Manufacturing (Pella, IA) makes Ford Tractor Foot Feed Kits for the 9N, 2N, 8N, NAA, 600, and 800 models. The Dowden foot feed allows the operator to use either the foot pedal or the standard hand throttle, freeing the right hand for shifting and/or running the hydraulic control for a loader, dirt bucket, rear blade, etc.
