I'm using P1k5 to pull a 200 gal weed sprayer and need to be able to keep a constant speed to apply the appropriate herbicide rate evenly. I'm trying to go 6mph at around 3000-3200 rpm. I used a planer to skim some 2x4's to place under the gas peddle. It works, but is a pain to move boards back and forth from under the gas peddle when going in reverse. Does any one have any suggestions? Is there an electrictronic throttle control? Is anyone else going to do any spraying with their pioneer?
