2 Description

Description

The brush on this engine driven device is for brushing artificial
grass both for installation and maintenance and has been
especially designed and made to our own specifications.

The special fibers in the brush prevent any damage to the
artificial grass fibers in the turf while still performing the proper
cleaning and comb action.
It will make the seams less visible, remove debris, comb the
fibers, and brush the infill (if applicable).

The 4-stroke petrol engine requires little maintenance and is
very economical. Wide handle- bars give good directional
control and good grip.

Replacement brushes can also be ordered at Henko A&T B.V.
