EL 22 - 92

The rotor is driven by hardened steel gearwheels located in the thick-walled side gearbox. The oversized chain with automatic tensioning is fatigue-resistant and lubricated in an oil bath. On the large power tiller models, the rotor drive is ensured by forged and hardened steel gearwheels, mounted on tapered roller bearings for maximum capacity. The lower bearing is equipped with a cassette seal to withstand leakage and contamination in abrasive soils. For the EL 22 power tiller designed for intensive use, the drive is equipped with a torque limiter and the central gearbox is also maintenance-free.

On EL 43 and 53 models, the central gearbox is mounted directly on the tiller frame. It is offset, as is the 3-point frame which avoids unfavourable drive angles. This makes it easy to work under trees and along edges.
On EL 62, 82 and 92 power tiller models, the central gearbox is set backward for reduced PTO angles. On the EL 92, the Duplex gearbox offers 4 rotation speeds with the optional gear set to allow the operator to adjust the rotor speed to match the conditions. The EL 62 model also offers a Duplex transmission where two speeds are possible by inverting the gearwheels. The entire driveline is protected by a friction torque limiter.

The helical shape of the KUHN blades ensures:
- cutting and mixing of plant residues,
- aggressive penetration into hard soils while requiring less power,
- increased clod crumbling.
The EL 43 power tillers are equipped with four blades per flange and all the other models have six for even finer crumbling. In order to perform shallow work, L-blades are also available for the EL 53 and 92 models.
