Please call or email us with your lawn mower's make, model & deck width if you are unsure which of the 4 versions will fit your mower. All versions are commercial grade, the difference is the layout of the components to ensure they fit your mower's deck configuration.

The flap may not clear the deck when in the fully open position like the Mini HD model but the motor is mounted vertically to make its footprint on your mower's deck even smaller.  This means you may need an extra inch or two to fit through tight gates.

It is a little cheaper than the larger HD model, but other than the motor, all components are the same as HD model. The motor uses gear made from brass and is made in Spain.  It operates at 40 RPM, which allows for finer positioning of exactly where you want the flap - Open, closed, or in-between/half-open.  This gives you full control of the grass clippings!

If your lawn mower is a pull start, you must add a battery. Learn more about using the Grass Flap/Chute Blocker HD Model with a lawn mower without a battery.

We recommend the rubber flap, but it is just a personal preference. The reason we recommend the rubber flap is that it is more forgiving. Even the most careful lawn mower operators can get a little too close to a fence post! The rubber will snap back into shape, while the aluminum flap prefers to bend.

Shave Seconds Off Mowing Each Lawn and Mow Safer

Professional lawn mowers know every second saved equates to more profit.  Become more efficient by automating your lawn mower's grass flap.  It is also much safer than sticking your hand or foot down by your lawn mower blades to open and shut it manually.
