Kuhn North America has introduced new pull-type GA 4230 T and GA 4231 T single-rotor hay rakes, each with a 13.10-foot (4.2-meter) working width to its lineup of single-, twin-, and quad-rotor rotary rakes and wheel rakes. Designed for easy operation, the new rakes enhance Kuhn’s previous single-rotor rakes through the addition of the patented, exclusive KUHN Masterdrive GIII double-reduction gearbox technology, which the company says improves power flow through the gearbox and enables the “ergonomic benefits of right-hand swath delivery.” The rakes are designed for use with heavy crops, tough field conditions, and intensive use.

“Unrivaled” Performance

The Masterdrive GIII gearbox and rakes include such improved key components and features as an aluminum-alloy housing, optimized cam tracks, bigger follower bearings, tine arms featuring large-dimension bearings, a stronger pivoting tine support shaft, a reinforced main shaft, and more durable tine arm mounting for the tine holders. Kuhn says the result is an “unrivaled” ability to move heavy, wet crop, gentle handling of dry hay, and neat windrowing of corn stalks.

Both the new GA 4231 T and GA 4230 T have a 11.75-foot transport width. With its removable tine arms, however, the GA 4231 T can reach a 6.5-foot transport width. The GA 4230 T’s tine arms are fixed. (Photo courtesy of Kuhn North America.)

Convenient Transport & More

Both rakes have a 11.75-ft (3.6-m) transport width. The GA 4231 T, however, has removable tine arms that can be stored on the hitch to help reach a slimmer 6.5-ft (1.95-m) transport width. (The GA 4230 T’s tine arms are fixed.) Both rakes’ right-hand delivery design provides maximum efficiency and operator comfort, as the windrow and tractor controls are both on the right side to enable simultaneous adjustments and rake-quality monitoring, Kuhn says. The rakes’ double-curved tine arms, hydraulic headland lift, and tandem axles, meanwhile, help them tackle challenging, hilly terrain. The double-curved tine arms form fluffy, straight windrows for “superior raking at high speeds,” and the hydraulic headland lift enables smooth, easy turning to clear previously made windrows, Kuhn says.
