What is the difference between a 3-Pt. mounted and pull behind chisel plow?
All Three Point Hitch mounted implements transfer some implement weight and some draft force to the tractor rear wheels when the Top Link is slack, improving rear wheel tractor traction. When the Top Link is in compression, a more limited amount of implement weight and some draft force is transferred to the front wheels, improving front wheel traction, especially with 4-WD tractors.
Note that Buckeye Tractor's Chisel Plows for
compact tractors are all Three Point Hitch models.
Pull type Chisel Plows put all the implement weight on the shanks, assuming chisel gauge wheels are out of soil contact, so in theory could penetrate deeper. However, the tractor will have less tractive power. So pull type Chisel Plows require a tractor with options to increase tractive power (4-WD, loaded tires, wheel weights, R1/ag tires, dual rear wheels on each side, etc.) and a lot of engine power output.
Pull type Chisel Plows articulate (follow ground contour) independently of the tractor.
Pretty much the same for Three Point Hitch vs towed Disc Harrows.
Pretty much the same for Three Point Hitch vs towed Cultipackers, except even 1,200 pound Cultipackers require little tractor traction nor power to pull, as Cultipackers roll over soil surface.
