GrassFlap™ Chute Blockers for Warhawk Mowers

A Direct-Bolt Chute Blocker Built for Cleaner Control

Operating a zero-turn mower requires clean control for more than just cut quality. Controlling where the grass goes determines how clean the property looks when the job is finished. It also affects an operator’s ability to move around beds, fences, sidewalks, driveways, buildings, vehicles, and property lines.

GrassFlap™ continues to expand its lineup of mower-specific chute blocker systems, including options designed for Warhawk Brand Mowers.

One example is the 43UM70-5-B31 GrassFlap® brand chute blocker Direct Bolt with Steel Blocker Plate and 5 Pedal, designed for the Warhawk Commander Pro. It gives operators an all-steel foot-operated way to control mower discharge without drilling into the mower deck or foot platform.

Homeowners, property managers, and professional lawn-care crews use GrassFlap discharge chute blockers as a practical upgrade for managing clippings, improving control, and reducing unwanted blowout in sensitive areas.

What Is a GrassFlap™ Chute Blocker?

A chute blocker is an operator-controlled discharge chute, often called an OCDC. Its purpose is simple: give the mower operator more control over where grass clippings and debris exit the mower deck.

On zero-turn mowers, this matters because operators are constantly mowing around obstacles. A mower may need to discharge freely across open turf then pass a mulch bed, sidewalk, parked truck, fence line, driveway, or building entrance. 

Without discharge control, grass clippings can end up exactly where you do not want them.

GrassFlap™ chute blockers solve that problem by allowing the operator to open, close, or control discharge from the mower while staying in position.

GrassFlap’s Warhawk-compatible unit is an ideal OCDC. Its chute blocker plate opens a full 180 degrees and clears the edge of the mower deck so the mower can still fit in tight spaces.

Warhawk Chute Blocker Example: GrassFlap™ for Warhawk Brand Mowers

The GrassFlap™ 43UM70-5-B31 is built for operators who want a durable direct-bolt chute blocker for compatible Warhawk Brand Mowers.

This product includes everything needed to install and operate the GrassFlap® chute blocker, including:

• All-steel flap assembly that mounts to the discharge opening

• 5 Pedal

• 70-inch cable

• No-Drill Mount 1294

• Clamp Plate 1256

• Mounting hardware

This particular chute blocker is compatible with the Warhawk Commander Pro. Installation involves a direct bolt to existing holes on the deck and foot platform, with no drilling required.

The direct-bolt no-drill design preserves the mower setup while making installation more straightforward. For professional crews, less fabrication means less downtime. For homeowners, it makes the upgrade feel more accessible.

Why GrassFlap™ Chute Blockers Make Sense for Warhawk Zero Turn Mowers

Warhawk mowers are built for speed, precision, power, 360-degree maneuverability, intuitive controls, and efficient fuel use. Those traits are exactly why discharge control becomes important.

A fast precise mower needs clean management of clippings. Operators will move through tight spaces, around beds, near edges, and across mixed-property conditions. A GrassFlap™ chute blocker gives the operator another layer of control.

For open turf, the chute can remain open. Around landscaped areas, driveways, walkways, or bystanders, the operator can close or manage the discharge. 

That flexibility is especially helpful when mowing residential lawns, commercial properties, schools, athletic fields, municipal spaces, and high-visibility landscapes.

All-Steel Construction for Real Mowing Conditions

Durability matters in mowing equipment. Chute blockers are installed at the deck discharge area. This exposes chute blockers to the following:

• Vibration

• Grass buildup

• Repeated movement

• Moisture

• Daily jobsite conditions

The GrassFlap™ Warhawk unit includes an all-steel blocker plate that can handle repeated operation in demanding mowing conditions.

Benefits for Homeowners

For homeowners using Warhawk Zero Turn Mowers, GrassFlap™ can help make mowing cleaner and more controlled.

Instead of blowing clippings into mulch beds, gardens, patios, pools, gravel, sidewalks, or neighboring lawns, the operator can manage discharge as conditions change. Larger residential properties can benefit from a zero-turn mower used around multiple landscape zones.

The foot-operated design allows the operator to control the chute without adding unnecessary interruption to the mowing rhythm. Homeowners who want a polished finish can reduce cleanup time and help protect the look of the property.

Benefits for Professional Lawn Care Crews

For professional mowing crews, time and presentation matter.

A commercial crew may mow dozens of properties in a day. Each property has different obstacles, customer expectations, turf conditions, and cleanup needs. 

Chute Blockers reduce unnecessary mess around:

• Flower beds

• Sidewalks

• Roads

• Vehicles

• Customer-facing areas

The GrassFlap™ Warhawk chute blockers are relevant here because these chute blockers combine: 

• Direct-bolt installation

• Foot-pedal operation

• Give control of discharge to the operator

• All-steel flap assembly 

Crews running compatible Warhawk equipment can readily add discharge control without overcomplicating the mower.

Cleaner discharge control results in a professional finish. When customers see the property immediately after the crew leaves, there is a sense of not just a job well done, but a job done cleanly. 

Installation Notes and Fitment

The 43UM70-5-B31 GrassFlap™ unit installs by direct bolt to existing holes on the deck and foot platform, no drilling required. Listed for the Warhawk Commander Pro, GrassFlap™ recommends using its product lookup to verify fitment for a specific mower.

Before purchasing, operators should confirm mower model, deck configuration, and compatibility. Before installation or maintenance, shut off the mower, allow moving parts to stop, and follow the mower manufacturer’s safety instructions.
