A 2-part tool holder carries vertically aligned slotted knives with soldered-on all-steel plates, which as a layer breaker loosen the hardened soil.
Both knife receptacles are equipped with a separate NON – STOP external body fuse.
This safety device allows the slit knives to move upwards when hitting objects like stones in the ground and then return them to the working position by springs.
The water-filled hedgehog roller is equipped with interchangeable special tines made of tool steel. The spirally arranged tines, combined with the high working speed (up to 10 km / h), ensure effective comminution and mixing of the covering as well as the effective and gentle incorporation of the applied support grain. The print run of the hedgehog roller is adjustable. The hedgehog roller can be suspended or rigidly fixed.
An adjustable spring tine bar provides for the pre-setting and the downstream leveling rail for an exact planum of the machined surface.
After the ground is backfaced by the pressure of the heavy-walled, water-fillable smooth roller, the height-adjustable and side-shiftable follower brush allows an optimum smoothing of the surface.
The trailing brush is exchanged for the trailing rake when a constant roughening of the lining is required in order to establish a connection of the carrier layer with the outer layer to be applied.
The adjustment of slitheads, hedgehog roller, spring tine bar, leveling bar and follower brush are made by means of smooth, scaled spindles, which allow an exact working depth adjustment.
The trailing unit consists of water-fillable roller, central spindle and follower brush or alternatively trailing rake. It can be mounted to the basic device of the feather tine leveler as well as the drained surfaces and paths renovator with a few handmovements and without tools and must be bought only once when the basic devices are combined.
The operation of the drained surfaces and paths renovator without forced drive allows a gentle treatment of the support grain, without producing significant zero components.
This is the main difference to devices, which are forced by an articulated shaft or oil motor.
