Machine description and purpose of use
The RHD OPEN series of machines are ‘3-point linkage’ tractor mounted universal flail
mower/shredders designed primarily for the mulching of grasses, brambles, small bushes,
branches, vines, and general crop residues. Their tough construction, working widths of 2.3,
2.5 or 2.8m and offset makes them ideal for maintenance use in all green areas, vineyards,
orchards, on verges and in scrubland by farmers and contractors alike.
These machines should only be used to perform tasks for which they were designed – use of
the machine for any other function may be both dangerous to persons and damaging to
components and is therefore not advisable.
