Slashing

Slashing

Slashing uses a large mechanical cutter attached to a tractor to reduce the body of gorse. Slashing works best for large gorse patches although it is not suitable for large mature woody gorse because of physical design limitations. The slasher will not reach gorse below the slasher cutting level and slashing can encourage gorse to flower and seed at lower height levels.
