KUHN GMD 30 Series rear mounted mowers deliver a clean cut with a wide cutting width and are ideal for large-acreage producers. These mowers provide high reliability and quick cutting to help produce quality forage at a high output. The high-lift discs and Lift-Control® hydropneumatic suspension ensure excellent cut quality and crop throughput, even in the toughest conditions. Fast-Fit® knives and the Optidisc® Elite lubed-for-life cutterbar take the time and headache out of regular maintenance. Should the mower strike an obstacle while working, the continuous hydraulic safety automatically pivots up and back, minimizing the risk of damage. At the end of the season, store your KUHN GMD mower without any problems thanks to the vertical storage position of the machine.

For the ultimate triple-mower combination, pair one of these models with a KUHN GMD 25 F Series front mount mower, and take productivity to a whole new level. The total combined working width of up to 32’6” knocks down large fields in no time, while exclusive features provide strong returns on investment by reducing maintenance and downtime.
