The Gramline 8 M injector machine has its own axle and is therefore particularly suitable for the attachment of manure tankers, whose axle load is already exhausted through the loading with liquid manure. The injector machine is suitable for the slurry on grassland and arable land.
The device can be attached to all manure tankers, for which the approval of the manufacturer has been obtained. The working width is eight meters. For the applied driving lane distance between 15m or 30m it is possible to switch off the two outer tubes through a ball valve. Through this, the working width is reduced from 8 meters to 7,50 meters.
For road transport, the unit is folded up. In the transport position, it has a width of 2.96 meters and a height of 3.78 meters. The device is equipped with its own light bar which has a length of 4.47 meters.
The device is equipped with 32 discs to open up the soil. The distance between the discs is 25.5 cm. The discs have a diameter of 46 cm. A disk has a width of 5 mm. If the liquid manure distribution is to be performed on loosened soil, all 32 discs can be fitted with a disk attachment to perform a widening. This attachment is attached to the base disk with four screws. Through the widening of the discs a wider slot is created in the processed soil, which can absorb more liquid manure.
Each disc has maintenance-free bearings with an oil bed. Scrapers for the discs are offered optionally. The device does not have a drip stopper.
The Gramline 8 M injector machine is equipped with two Harsø distributors to distribute the manure. Each distributor has 16 outlets.
A levelling bar is attached behind each pair of discs. During the liquid manure injection on machined loose soil this levelling unit closes the soil again into which the liquid manure was inserted. The levelling bars are adjustable in height. The operator at the terminal can execute the functions for lifting/lowering and folding/unfolding. The entire hydraulic system of the injector machine is powered by the tractor through load-sensing.
