Description

The Groundsmaster® 4000-D rotary mower boasts a powerful turbo-charged 55 hp (41 kW), Tier 4 Final and Stage V compliant diesel engine. Featuring Smart Power™ technology, high engine torque and patented, HybridDrive™ cutting deck system, the Groundsmaster 4000-D delivers power where you need it most, no matter how tough the conditions. With its excellent trimming capability and an ability to mow a 0” uncut circle, the Groundsmaster 4000-D is an extremely efficient mower.

The parallel hydraulic traction system maintains consistent hydraulic flow between the front and rear wheels to assure full time 4-wheel drive. This allows you to mow with confidence, even on hills and wet grass. Operators can enjoy the open air with ROPS safety in the Groundsmaster 4000-D.

  • 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.
  • 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.
  • 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.
  • 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 allows you to trim how you want with one, two, or all three decks engaged, depending on the situation.
  • 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.
  • Lets you set traction unit for a continuous operating speed with automatic override when operator moves drive pedal or operates brakes.
  • 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.
  • Accessories for added value and versatility: rotary broom, 2-stage snowthrower, debris blower, and road package kit.

Configuration Options:

  • Groundsmaster 4000-D with ROPS
  • Groundsmaster 4010-D with All-Season Safety Cab

Product 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.
