The DIGIDRIVE system

DIGIDRIVE: revolutionise tedding

When a KUHN engineer invented this drive concept, tedding entered a new era.
From that moment on, it became possible to drive a very large number of rotors and fold them to an incredibly compact size, and all this without any maintenance. A real revolution!
Since the launch of the DIGIDRIVE finger drive system twenty years ago, more than a million rotors have been working all around the world, tedding forage with exceptional reliability. The DIGIDRIVE system is made of case-hardened steel and requires no maintenance.

Rotor housings made to last

The guidance is done large-diameter, double-row angular ball bearings (1). Thoroughly sealed to prevent lubricant leakage and impurities getting in (2). Robust mounting on the rectangular frame with spacers and long through-bolts (3). With these rotor housings, greasing points are limited to a few pivot points, allowing you to spend more time in the field and less doing maintenance!

Individual oblique positioning

Each wheel is easily adjusted obliquely, no tools required, for accurate border tedding without losing or wasting precious forage.

Top quality forage

Tedding long and dense forage with large diameter rotors

GF 502: for tedding long and dense forage

Equipped with four rotors and six tine arms, GF 502 tedders are the ideal tools for spreading large swaths.
The large diameter rotors are specially designed to handle long and dense crops.

GF 422, GF 582 and GF 642: top quality tedding

Experts are convinced and those who use them swear by them. For farmers whose goal is to harvest a first class crop there are so many advantages to having small rotors:
  • Working with a wide angle of attack while turning the crop
  • Fast and uniform drying.
  • Fully effective crop inversion.
  • Uniform distribution.
  • Exceptional ground adaption.
  • Mounted tedders with less overhang to reduce lift requirements.
  • Reduced power requirement. requirement.

Integral pick-up with asymmetrical tines

Asymmetrical tine length with longer outer fingers produces high quality tedding. The outer finger moves into the forage earlier compared to a symmetrical design. This ensures a more complete tedding operation, even on field borders and between rotors (C) (E), due to better tine overlap in this tricky area. Moving into the forage earlier means that the actual working width of each rotor (therefore the machine) is larger.

Ground and tractor following

Rotor lock - totally safe transport

Rotor lock - totally safe transport

Activate the hydraulic valve and the tractor lift raises the rotors for transport. In this position the rotors are automatically centred and locked for fast and safe transport.

Pivoting headstock for optimum ground following

At work, the rotors the tractor thanks to the pivoting headstock - a real advantage for ground contouring and preserving plant stubble.
