Haying equipment manufacturer Kuhn had a lot to talk about last fall. It introduced a number of updated new models to its rake and tedder lines.
The new GF 1003 series tedders include both pull-type and three-point hitch-mounted models. They use the brand’s new OptiTedd small diameter rotors that the company says are stronger than previous designs. And the smaller diameter also allows them to follow ground contours much better.
The DigiDrive coupling systems that turn those rotors make for an efficient driveline design capable of better transferring drive power while still allowing the tenders to easily fold up into transport position. The DigiDrive driveline design requires a minimum of maintenance without the need for daily greasing.

The new GA 13231 and 15231 quad-rotor rakes are available in working widths from just over 27 feet to 48 feet and three inches, making it possible to cover a lot of ground in a short time. Kuhn says the rotors on these rakes are now lighter, yet stronger. They also boast updates to some bearings and shafts to increase overall implement strength.
A “boost function” allows the front rotors to rotate 20 per cent faster than those at the rear, which reduces clumping and makes for a better windrow.
ISOBUS controls allow the operator to adjust all rake settings from the cab, including working and windrow width, simultaneous or individual front rotor lift, raking height and machine folding for transport. Two monitor options are available, the CCI 800 and CCI 1200. Both use touch screen technology. A programmable joystick and camera are also available as options.
Finally, the new lightweight GA 4201 and 4401 single-rotor mounted rakes are now offered for smaller tractors. They use double-curved tine arms to create fluffy windrows that allow more air movement through the windrows for faster drying. Rake height adjustments are made with a crank mechanism that is accessible from the tractor operator position.
These rakes also use a pivoting headstock that allows for tight turns of up to 48 degrees, making it possible to get into tight field corners. An improved gearbox makes for a more durable design and simplified windrow curtain adjustment allows for greater operator control.
