Hieta-Heikki gritter buckets are pendulum-based gritters designed for demanding professional applications. Thanks to an adjustable hydraulic motor, the moving base plate spreads grit across an area approximately 0.5 to 0.7 metres wider than the bucket, making it easier to avoid poles and traffic signs.
The pendulum-base design withstands impacts from rocks and other debris well and has proven to be extremely reliable. Grit consumption can be controlled by changing the gap between the base plate and tank or by changing the speed of rotation.
Hieta-Heikki gritter buckets can be attached to the tractor’s rear linkage, where they are self-loading by means of a connecting rod and hydraulic cylinder, or they can be attached to the front loader with a separate adapter.
