Description

Tillage implement.

Me invention "relates to a soil cultivation device! In particular a soil cultivator with at least one die Machining tools bearing, stored in the device frame Tool shaft, which via a gearbox from an internal combustion engine is driven, the crankshaft on the one hand a flywheel and on the other hand a camshaft controlling the valves drives'.

You have previously known devices of this type as a result of upright drive motor has a very high construction, which means that the use of the device only has a negative effect unplanted soil is restricted.

It is now the object of the present invention to eliminate this disadvantage of the known devices and by reducing them The device height ensures that the devices can be used widely. According to the invention, this object is achieved in that the combustion engine is attached to the device frame - to the flywheel attached to the side, flanged to the side, is, and the Ifoükenv.relle is coupled to the gearbox for driving the tool shaft. In this way - the overall construction <- height by the considerable distance between the axes of the crank

To make the device easy to handle and operate to be ensured, it is to be ensured according to another standard useful, a disengageable clutch in the device frame, to store a multi-speed manual transmission and a sprocket shaft, the latter via a drive chain with is coupled to a sprocket that is stuck on the tool shaft.

The transmission links 11, 13 and 19 thus lie in an axis NW, which is at a certain distance is above the crankshaft axis KW. The highest point of the motor 18 is lower by this distance KW-KW than when the * drive torque is taken directly from the crankshaft 23. The overall height of the tiller is thus around this distance is lower. This tiller can or the like under lying branches. used without difficulty will,

Two handles 24 »which are anchored on the device frame 1 are used to guide the tiller, while they provide support of the device, a sliding spur 25 is used, which can also be clamped to the frame 1, adjustable in height.

This cover plate is attached to the housing of the motor 18 from below and extends like a cap upwards and backwards over the entire motor 18 and partly also over the switching £ reefs 16.17.
