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.

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.

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

Operators will like the Groundsmaster® 4000-D/4010-D because it is amazingly quiet. Its low engine speed, low-noise technology gear motors, and a variable-speed cooling fan clutch all contribute to greatly reduced noise levels. Plus, amenities like air ride seat suspension, a multi-size beverage holder, 12-volt power outlet, and a portable radio holder make work more comfortable.

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.

There's no need to worry about mowing around objects while traversing hills, even in wet terrain. The parallel hydraulic flow between front and rear wheels assures full-time 4-wheel drive. And the individual wheel brakes provide effective traction assistance on wet turf.

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.

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

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.

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.

The Groundsmaster® 4000-D/4010-D delivers 55 hp (41 kw). With so much power at your disposal, it's easy to digest even a large amount of wet, thick grass. With its unmatched engine torque and patented hydraulic motors that directly drive spindles on each deck, the 4000-D/4010-D delivers power where you need it most to cut tough grass. Plus, the shallow deck design forces quicker clipping dispersal, allowing the decks to accept more grass on a faster basis.
