When it comes to tines that actually engage the crop, KUHN leaves nothing to chance: top-quality raw material has been wound into four coils with long tine fingers, giving you exceptional reliability. A defined attachment system to the arms results in an unmatched design life of at least 180,000 cycles. This provides several hundred hours of work before tine replacement is necessary. Asymmetrical tine finger length means both fingers engage the crop equally for a more consistent pickup. The tine guards prevent accumulation of debris around the coils.

Whether in long or short, wet or dry crop, or different cutting heights, the pitch angle is adjusted without tools near the wheel supports. Always remember a steep pitch angle will decrease drying time and increase the nutritional value of the forage.

The asymmetrical tine length with longer outer fingers has several advantage to bring the machine’s tedding quality to perfection. This allows the outer finger to touch the crop earlier compared to symmetrical tines. It also ensures more complete tedding, along borders and between the rotors, where the tines overlap more in this sensitive area. Contacting the crop sooner means that the actual working width of each rotor is expanded and as a result, the entire machine working width is expanded.

Standard Headland Lift Control, on GF 1012 T Series tedders, makes the machine easy to lift and maneuver on headlands while limiting the introduction of foreign materials like dust into the forage. This is beneficial because the headlands do not need to be tedded twice. One hydraulic valve in the cab lifts all the rotors from the ground providing high ground clearance to pass over windrows (approx. 20”) and allows operators to easily turn on headlands or narrow areas.

With rotors driven by DigiDrive couplings and lubed-for-life rotor housings, the greasing points are limited to a relatively few pivot points allowing you to spend more time in the field and less time greasing.

1. They are supported by large diameter, double-row angular ball bearings.
2. The thoroughly sealed rotor housing prevents lubricant leaks or introduction contaminants.
3. The robust mounting of housings to the edge of the rectangular frame maximizes strength and durability.

The two outer sections of the tedder are held in place by straps. They are used to reduce stress on the main frame and rotor structures. This allows fastening to the rotor ends, keeping the two sections stable without any oscillation. The straps also double as safety guards, replacing the metal guards. When folding for transport, the two straps automatically wind up like a seat belt.

The 16 rotors of the GF 17012 follow changes in terrain as well as (2), eight-rotor or (4), four-rotor tedders. The GF 13012 and 17012 come standard with GSC (Ground Save Control) system which allows the rotor gear to train to swing independently of the carrying frame.

These machines have excellent ground following with their small rotors that are each 5’ in diameter, which allows for uniform tedding across the whole field. There is individual articulation between each rotor and equal spacing between the rotors and tires for better ground following.

Operating in short, sticky crops or long, late season crops can be a challenge when the crop wraps in the wheel column, resulting in frustrating downtime spent clearing the mess. These tedders are fitted with crop deflectors as standard.

Unfolding or folding operations are quick and easy using the in-cab control box. Time lost when changing fields is reduced to a minimum so you can focus on achieving maximum daily output.

The folding system allows the transport wheels to lower and combine with the rotors tilting forward. While in transport position, height is reduced, load distribution on the tractors is optimal and road transport at high speeds is ideal. The incredibly narrow transport width of 7’10” on GF 13012 and 17012 (9’10” on GF 8712 T and 10812 T), and the wide transport undercarriage combine for easy maneuverability and stable road transport.
