Large-diameter wood and brushy debris are no match for the HG8000 horizontal grinder. No need to cut it down to size: this monster of a machine has the largest infeed opening in its class and the power of a 1050 hp/783.3 kw CAT Tier 2 engine. Dual planetary feed roller drives push material into the drum with outstanding efficiency. Extra-wide load-out conveyer lets you drop processed wood where you want it without slowing down the grinding action.
Get up and running quickly with four pre-set infeed settings that control the material’s finished size.
Increase productivity thanks to the exclusive Vermeer SmartGrind system, which automatically controls grinding speed based on engine rpm levels.
Improve cutting performance using the patented series II duplex drum system with reversible hammers and cutter blocks that simplify maintenance and nearly double wear life.
Change screens easily with the on-board screen handler system.
