Major Mowing Capacity

The Groundsmaster® 4100-D/4110-D delivers 58 hp (43.3 kW) and 125 ft.-lbs (92.2 N) torque at 2000 rpm. 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 4100-D/4110-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.

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.

Superb Trimming (GM 4100/4110)

In addition to effectively mowing a 54" to 10.5' swath, the Groundsmaster® 4100-D/4110-D offers incredibly tight trimming capabilities. It allows you to trim how you want with one, two, or all three decks engaged, depending on the situation. The 4100-D/4110-D also features a unique, patented, 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.

Superior Traction

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.
