Features
Easy Service
Quick and easy access to all major service areas.
Lighter Weight Design
Optimized design and use of lightweight materials means less weight and turf compaction without sacrificing performance and functionality.
Productivity
The Groundsmaster® Contour Series mowers provide the productivity you need, no matter the size. Mow up to 10.6 acres (4.3 hectares) per hour to get the job done fast.
Contour® Plus Cutting Decks
The Contour™ Plus cutting technology takes quality of cut to a whole new level. Air inlet pockets keep the grass standing tall for the cleanest possible cut and a modified rear discharge opening disperses clippings more evenly. An optional mulching kit and optional high height of cut blade are also available.
Air-Ride Seat Suspension System
Convert the standard seat suspension to air-ride for rough applications to provide more comfortable ride for operators logging long hours in the seat.
CrossTrax® All-Wheel Drive
Based off our patented series/parallel 3-wheel drive kit, the CrossTrax® system automatically transfers power from the front tires to the opposite rear tires to minimize spinouts and maximize traction on wet terrain.
Operator Comfort
All of the indicators and controls to operate the unit are conveniently located on the right armrest. Control console pivots back for right hand entry and exit. Tilt steering, deluxe suspension seat, improved visibility and lower operating noise enhance the operator experience and help to reduce fatigue.
Durable Design
Proven rugged frame, drivetrain, and components ensure durability and long life. Heavy-duty welded steel decks and frames provide extra durability and long life.

Accessories and Attachments
Atomic® Mulching Blades
Atomic® mulching blades feature an aggressive "tooth" design that shreds grass and leaves into small particles. The teeth curl upward behind the blade to suspend clippings in the chamber so they are cut and re-cut until they virtually disappear.
Leaf Mulching Kit
Mounts to the deck to pulverize fallen leaves into fine mulch.
Sunshade
Stay cool and productive when mowing with a GM Sunshade
