Soil Stabilizer PRONAR SGD-25Z

The SGD-25Z soil stabilizer is an efficient machine powered by the tractor’s PTO and mounted on its rear three-point linkage.
The drive from the tractor is transmitted via a universal telescopic shaft to a central gearbox, which then drives the working shaft through belt and cylindrical gears.
The reinforced drive system structure ensures optimal performance in tough working conditions.
The working shaft is equipped with mounts for replaceable round milling cutters with carbide tips, providing high efficiency in soil processing.
The machine is standardly equipped with hydraulically adjustable side flaps and a rear flap, as well as a hydraulically controlled working shaft height adjustment.
A variable mixing chamber allows precise adaptation of the stabilization process to field conditions.
All functions are controlled via a joystick mounted in the operator’s cabin. Additionally, the machine can be fitted with various types of rear flap scrapers, an anti-blade plate, and rear road lighting.
APPLICATION
The SGD-25Z stabilizer is intended for soil preparation prior to compaction by mixing previously spread stabilizing agents, which increase the bearing capacity and cohesion of the substrate.
