Features

Reliable Powertrain

The engine throttle-by-wire makes it easier to get to high or low idle and the electronic isochronous engine governor allows for a faster engine recovery time with no engine droop. The two speed drive motors improves hydraulic efficiency allowing the mower to operate at 4WD in mow and transport, improving fuel economy.

Nimble Maneuvering

The impressive trimming capability means you can get around even the smallest object. The rare ability to mow a 0" uncut circle - without wheel brakes - allows you to easily mow striping patterns without leaving any grass uncut. Smooth turning is made possible by a tight 55.5" (141 cm) wheelbase and an inner, rear-steering turning angle of 53.5 degrees.

Smart Power® Traction

Smart Power Traction allows even an inexperienced operator to achieve a consistent cut, even on hills and thick patches. By automatically adjusting ground speed when encountering heavy cutting conditions, optimum blade speed is maintained.

Easier Maintenance

The Groundsmaster® 4000-D/4010-D mowers are easy to service and requires fewer parts to stock. That's because the four drive belts, and the deck motors, blades, spindles, idlers, and spindle pulleys are all interchangeable. While rear discharge decks come standard, you can easily convert to Guardian® Recycler® decks which offer improved clipping management and additional safety.

SmartCool™ System with Auto-Reversing Cooling Fan

Variable speed, temperature actuated reversing fan. Blows chaff off intake screen to help reduce overheating. Big time saver which reduces that amount of times an operator has to stop and exit the unit to clean the back hood.

Superb Trimming

In addition to effectively mowing a 62" to 11' (157.5 cm to 3.4 m) swath with its fast wing lifts, the Groundsmaster® 4000-D/4010-D offers incredibly tight trimming, allowing you to use one, two, or all three decks. The 4000-D/4010-D also features a unique, patent pending, parallel hydraulic traction system in forward and reverse that makes it much easier to trim around a tree or object without scuffing even while traversing a hill.

Durable Design

Heavy-duty welded steel decks and frames provide extra durability and long life. Each wing deck features a bi-directional, impact absorption system. If a deck hits an object, a spring-loaded cylinder allows the deck to flex on impact, protecting deck components so you have less down time and more productivity.

Cruise/Speed Control

Lets you set traction unit for a continuous operating speed with automatic override when operator moves drive pedal or operates brakes.
