What the GMD 3150 Disc Mower is used for
The GMD 3150 is used to cut grass hay, alfalfa, and similar forage into an unconditioned swath. It is often followed by a tedder, rake, or separate conditioning operation as needed. Three-point mounting works well in smaller or irregularly shaped fields.
Why the Kuhn GMD 3150 Disc Mower stands out
The disc-and-knife cutterbar maintains a broad cut from a relatively compact rear-mounted mower. Individual discs and replaceable knives simplify routine cutting-component service. A breakaway system and guarded driveline help protect the machine during normal field work.
Buying a used Kuhn GMD 3150 Disc Mower
Inspect the cutterbar for leaks, bent discs, cracked housings, noisy bearings, and worn knife pins. Check PTO guards, gearbox oil, breakaway linkage, lift frame, and three-point pins. Excessive vibration or uneven skid-shoe wear can indicate prior impact damage.
