PUBERT INNOVATIONS
TILLER GEARBOX
During Vario tiller development, a very compact new gearbox was fully conceived by the Pubert R&D department in collaboration with a calculation office specialized in motor sport transmission.
It is equipped with 2 gears forwards and 1 gear reverse. It is a real technologic innovation, 2 international level patents were filed.
Its main asset is to offer a wide working axle rotation speed range: the choice and design of the actuator gear train insure a high torque over the whole range of speed, the engine power don’t decrease.
The rotation speed range allows a perfect adaptation to the type of work and kind of soil. It keeps a maximum performance with all its accessories.
Operation and use principle:
The combined action on the speed selector, situated on the handle dashboard center, and on the engine throttle lever, allows a tines speed rotation from 28 RPM to 165 RPM.
- Slow speed 1 : Thanks to the slow rotation of tines, it is possible to break a very hard soil or use a large range of accessories. By action on the engine throttle speed control, tines speed rotation is adjustable from 28 RPM to 67 RPM.
- Fast speed 2 : By choosing the fast speed, the machine could till, crumble or draw a trailer. Then the rotation speed range is from 67 RPM to 165 RPM.
- Reverse gear : On its center the speed selector has a reverse gear for maneuver on very slow speed for the operator safety.
Technical Description:
It is a heavy-duty and reliable gearbox, with cast aluminum housings and steel processed actuator gear train. The treated shafts are assembled on ball bearings, everything lubricated by liquid grease.
The gearbox assembly is done on a semi-automatic mounting chain. A 100% dedicated test bench control validates the proper functioning of the whole production.
