The N267 spreader is adapted for coupling with the tractor hitch. The machine consists of
the following main assemblies:
- hitch system,
- top frame with vessel,
- spreading adapter,
- wheel system,
- hydraulic system,
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. The end of the load body features the manure spreading adapter, 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, remove the mesh guard from the spreading drums and make sure that
the mesh guard is installed on the front panel which protects the operator from injury by falling
objects, e.g. stones.
