A fond farewell Fella!
In a move that was always expected, well-known German grassland machinery brand Fella will soon be history in all countries around the world.
The Fella driveGUARD – an "ingenious disc" – can be retro-fitted at minimal cost.
Since stones and other paddock junk cannot be completely avoided, some risk of mower damage is always present, the company points out. And when it happens, the downtime and repairs are costly.
The driveGUARD sits outside the cutter bar under the mower disc. A two-part profiled flange connected by the overload disc and a roller bearing ensure torque is transmitted safely. The overload disc itself is a slotted steel plate. The shape and thickness of the steel plate, together with the slot profile, determine the safety area between the inner and outer ring offering precisely defined shearing torque.
If a foreign object blocks the rotation of a mower disc, the driveGUARD shears off at the defined breaking points. This interrupts the power train, and the mower disc turns freely. The mower disc remains firmly connected at all times to the cutter bar via the outer part of the profile flange. The sheared plate is simply replaced and work continues.
Because of the positioning of driveGUARD on the exterior of the cutter bar, costly damage to the gearbox, long downtimes and contamination of the oil circuit are prevented. Even the loss of the mower disc is safely prevented.
Mower owners can buy the driveGUARD as a wear part (for example, cutter blades) and replace the part themselves quickly and cost-efficiently.
Launched last November at Agritechnica, driveGUARD will become a standard feature of all new Fella disc mowers with compact angle drive.
