TerrainCut line of rotary mowers features GRIP all-wheel-drive traction system, which ensures that hydraulic traction power is maintained at all times. Wheel slip is minimized by diverting hydraulic flow from wheels that slip to wheels with grip. Mowers boast turbocharged diesel engines that provide the power to mow, climb or do both; Model 8800 delivers 43.1 hp, while Model 7400 delivers 37.1 hp. Double-yoke mounting system allows the decks a full range of motion independent of the hydraulic lift system, enabling mowers to conform to terrain contours. John Deere Golf, Cary, N.C.
