I am looking to purchase a Gravely 432 to pull a 60" york rake and other pulling duties where more power and traction is required than can be provided by a L or C8. The rake manual recommends a 12-15HP tractor. The Gravely 432 has a 13 or 14HP Kohler. I am currently using the rake with my church's JD GT245 with a 20HP Kawasaki and that works OK. (Would be better if I mounted the weights.) Is the Gravely 432 capable of this application? Does the drawbar have a height adjustment? The 432 has turf tires and chains. I may change to ag tires with weights or filled tires or all of the preceding to maximize traction. This will be my first Gravely rider.
No, the drawbar isn't adjustable on a 432 unless it came with the optional liftable rear hitch. Those are pretty uncommon unless you have a 450, in which case the liftable hitch was standard equipment.
