The HQ680 Tough Cut Mower is designed for mowing high grass, thick weeds, and heavy brush. A large baffled front opening helps direct materials into the deck and helps hinder debris from escaping.

Three heavy-duty blades counter rotate to cut and deposit waste evenly without windrowing. Capable of tackling saplings and large thorn bushes, the Tough Cut makes short work out of overgrown thickets.

The Tough Cut can be adjusted to three cutting heights: 3, 3 5/8, and 4¼ inches. Easy servicing of belts and pulleys is provided by the hinged and removable cover. The tilt-up deck provides easy access to the blades.

Ventrac Benefits

Heavy Duty Deck Shell

Heavy duty welded deck can handle the toughest cutting conditions and is built to last for years.

Counter Rotating Dual-Sided Blades

Blades spin in opposite directions providing for the better discharge of material. Mower blades are sharp on both sides so they can be used on right or left-hand spindles, allowing for double blade life.

Flip-Up Deck

Cleaning the deck and changing blades couldn't be easier with Ventrac's quick flip-up deck design. * HQ680 only

Extreme Duty Spindles

Cast iron spindle with 30mm diameter shaft and greaseable bearing.

No Shear Pins Needed

Ventrac decks are driven by a belt, not a PTO shaft. If the mower blade should get stuck on an obstacle, the PTO belt will slip rather than having a PTO shaft shear pin break.

Ventrac Mount System

With a little practice, you can switch almost any attachment within a minute, without any tools or heavy lifting.
