The manure spreader is intended for transport and spreading of loose manure. The manure spreader design
includes the load body with side panels and a chain conveyor which moves on the floor. The rear end of the load
body is closed by a articulated rear end wall with rubber seals along its bottom edge. The end wall is installed on
guides and actuated or positioned by hydraulic actuators. A horizontal conveyor drive shaft with socket wheels is
installed in the rear section of the load body. The shaft is propelled by a reduction gear coupled with a hydraulic
motor. There is a manure spreading adapter at the end of the load body, which consists of four vertical worm
screws with bolted shredding blades.
The spreader should be charged uniformly to ensure an optimum spread. The charging (loading) height must
not exceed the spreading adapter clearance height. Make sure that no larger solid bodies (stones and alike) are
present in the manure to prevent damage.
Prior to spreading, make sure that the mesh guard is installed on the front panel which protects the operator
against injury from falling objects, e.g. stones.
INFORMATION!
No person is allowed to remain on the machine or within its operating area when it is working.
In order to obtain an even manure spread, do the following actions in the indicated order:
- first increase the PTO's rotational speed to 540 rpm and then turn on the floor conveyor;
- spread enough manure in standstill until the required amount is fed to the spreading worm screws;
- then shift into the suitable gear and begin work.
Keep the PTO speed at 540 rpm to achieve the optimum spreading pattern. The spread layer thickness can
be adjusted by changing the floor shift speed and the spreader charging ratio. When making a return on the field,
decouple the PTO which will protect the jointed shaft and ensure a uniform spread. Install new shear pins if
the overload protection engages during the manure spreading and the shear pins of the shaft are damaged. Stop
the PTO and the tractor engine before replacing these components! The most common cause for pin shearing is
jamming of the spreading adapter by stones or large, hard chunks of manure.
