CoulterChisel Combines Coulter Blades



The CoulterChisel combines coulter blades with chisel shanks, making it a great option for those who want more residue sizing and mixing than a standard chisel plow can offer. It also includes a 4-bar harrow for ensuring a level soil profile.


The CoulterChisel has a row of gang-mounted coulter blades in front of the chisel shanks. You can choose from a variety of blade options, including flat, wavy and turbo designs, to match your tillage strategy. Duracoat blades with WEAR-TUFF lining are also available to extend blade life by as much as 3 to 5 times.

Adjustable Blade Depth

Adjust your tillage aggressiveness on the go by hydraulically raising or lowering the front coulter gangs from the cab. This feature allows blade depth to be adjusted independently of the chisel shanks.

Chisel Shanks

With a 6-inch pivot width, each chisel shank is formed “on edge” to reduce draft and improve residue flow. The shanks are spaced on 12-inch centers and offer more than 34 inches of frame-to-sweep tip clearance. They have a maximum tillage depth of 12 inches and a 15-inch trip travel.

Aggressive Springs

The aggressive springs help the sweeps maintain preset depth levels for consistent results. They come with a standard trip pressure of 1,000 pounds to help minimize damage from large rocks or other obstructions.


16- to 28-foot CoulterChisels come equipped with a hydraulic hitch, which is adjustable from the tractor cab. 32- to 40-foot CoulterChisels come standard with a floating hitch and front caster wheels, allowing these wider units to operate at a consistent depth and follow ground contours better.

Rear Hitch

The long-reach rear hitch for auxiliary trailering features an extendable swinging tongue for easy hook-up.

Mounted Harrows

The standard 4-bar mounted harrows can be adjusted for deep or shallow penetration. They feature a heavy, yet flexible design for floating over rocks and deep ditches.
