Single-disc fertiliser spreaders GP - trailed
Single-disc trailed spreader - disc drive from the ground wheels, spreading width 1–6 m, five hopper sizes.
In summer — spreading mineral fertilisers (granulates and dust). In winter — spreading roads and squares (salt, sand, mixtures) with appropriate implements. Details in the Winter and salt · Select options from an authorised dealer.

For whom
Wheeled Version
In the field and on access roads — GP suits farms and operators responsible for internal roads, yards and car parks where straightforward, predictable operation matters. For fertilising: it surface-applies granular and powdered mineral fertilisers on arable fields, meadows, stubble and pasture; two levers at the machine set the rate, while the road wheels drive the disc. For winter and site maintenance the same machine can spread salt and grit on roads and paths. It couples to a tractor or another four-wheel vehicle through the lower hitch; working speed is 6–14 km/h and permissible ground slope 8°.
The machine is attached to the lower hitch.
The frame is designed for connection to the tractor's lower hitch, not the three-point linkage. Unladen weight ranges from 56 to 120 kg depending on the model.
Wheel drive, no hydraulic system.
The disc is driven by the ground wheels via an angle gear. The spread rate and direction are adjusted mechanically, using linkages and sliders.
Spreading 1–6 m, operating speed 6–14 km/h.
Granular and powdery fertilisers, as well as road and sidewalk spreading. The vanes setting varies depending on the type of material: for powdery fertilisers, the vanes are set against the disc's rotation, for granular fertilisers, in line with the rotation.

Work stage1 / 4
The spreader is parked and hitched to the tractor's lower linkage. Both slide gates are closed, the levers are at zero, and the disc remains stationary.
The R and L levers open the slide gates above the two metering openings. The scale ranges from zero when closed to ten when fully open, and the selected position is locked with a pin.
During travel, wheel rotation is transmitted via an angle gear to the disc shaft—without a PTO. At a speed of 10 km/h the disc reaches 400 rpm.
Fertiliser falls through both openings onto the disc, and six vanes spread it with centrifugal force in a strip ranging from 1 to 6 m wide. The level in the hopper drops.

How the Trailed Spreader Works GP
Learn about the hopper, wheel drive, single-disc spreader, metering levers, and optional hitch of the machine shown.
Conical plastic tank
The tank has the shape of a truncated, inverted cone. The capacity is selected based on the farm's needs, and the fertiliser enters the device through two openings in the bottom.

Disc drive from road wheels
The wheel's rotation is transmitted via an angle gear to the disc. This means GP does not require power from the tractor's PTO shaft.

One disc with six vanes
The disc uses centrifugal force to spread the material. Adjusting the vanes changes the direction and width of the spread pattern.
