High-Quality Tines
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.
Asymmetrical Tine Length
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.
Two Rotor Designs
Choose between two rotor designs, depending on the windrow or swath width, or type of crop. The 7902 T GII features small-diameter rotors and is ideal for high-quality output. The small-diameter rotors ensure excellent tedding and are the key to fast drying, excellent ground adaptation and less impurities in the forage. Thanks to the steep pitch angle, the crop is fully turned over and well aerated for ultra-fast drying. The GF 7902 T GII tedder has eight rotors, each with five tine arms. The GF 5202 THA, 7802 THA and 7802 T GII, featuring four to six rotors with seven tine arms each, are ideal for spreading three large swaths produced by a 10’ mower. The larger rotors excel at handling long and heavy crop.
Quick Adjustment of Tine Angle
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.
Offset Border Tedding Along Field Edges
For clean, careful tedding next to fences or neighboring fields, GF 1002 T GII tedders are equipped with a border control system. On slopes, the border setting is particularly beneficial for controlling the direction of crop spread and obtaining an optimal spread pattern. On the GF 7802 T GII and 7902 T GII models, this setting is controlled hydraulically for absolute comfort. Simply activate a control valve and the machine is ready to work in border mode to the left or right.
DigiDrive® Coupling System – A Legend in the Making
When a KUHN engineer came up with this drive coupling design, we knew that it would revolutionize the rotary tedder. This patented design made it possible to reliably drive a large number of rotors, yet fold them for unmatched transport ease, all with virtually no maintenance or repairs. Since the DigiDrive coupling’s inception, nearly 20 years have passed and more than 150,000 KUHN tedders are now being used across the world to ted hay with the ultimate reliability. The DigiDrive contains case-hardened forged steel fingers for improved wear resistance. Synchronization of rotational movement is outstanding both in work and in transport where the components are folded 180° to reduce the machine’s space requirement. The DigiDrive is a highly reliable system requiring very little maintenance – no daily greasing necessary!
Rotor Housings – Made to Last
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. They are supported by large diameter, double-row angular ball bearings. The thoroughly sealed rotor housing prevents lubricant leaks or introduction contaminants. The robust mounting of housings to the edge of the rectangular frame maximizes strength and durability.
Crop Deflectors
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.
Folding System
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 9’10” and the wide transport undercarriage combine for easy maneuverability and stable road transport.
Auto Tine Height Control
When folding into the transport position, the tines automatically raise off of the ground for more clearance with the road. When unfolding into working position, the tines will reset to the working height the operator previously set. GF 5202 THA and 7802 THA only.
Standard Drawbar Hitch & Heavy-Duty Chassis
The GF 1002 T Series tedders all come standard with a drawbar hitch for simple and easy attachment. The heavy-duty chassis provides users with a fast and secure method of transport.
Transport Wheels
By locating the transport undercarriage in front of the rotors, on GF 7802 T GII / 7902 T GII models, only part of the weight is sustained by these central wheels, the rest is absorbed by the drawbar and the tractor. The spindles and tires on the central rotors of the GF 5202 THA and GF 7802 THA are stronger and larger in diameter to accommodate for transport from field to field.
