The Dosko swivel head eliminates that — wheel the machine to the stump, lock the wheels with a single lever, and sweep the grinding head across the stump in a natural arc. Less repositioning, less operator fatigue, faster completion time per stump. The side discharge frame directs grindings away from the machine and the operator, keeping the work area cleaner and reducing cleanup time.\u003c\/p\u003e\n\u003ch2\u003eGreenteeth® 700 Series — 3-in-1 Tooth System\u003c\/h2\u003e\n\u003cp\u003eThe 700 Series features a concave \"dish\" cutting edge that shears rather than shreds — cleaner cuts, less resistance, lower fuel consumption per stump. Each tooth rotates in three 120-degree increments for three fresh cutting edges before replacement. Eight teeth, three positions each — that's effectively 24 cutting edges per set before any hardware cost.\u003c\/p\u003e\n\u003ch2\u003eHonda GX390 — Cyclone Air Cleaner\u003c\/h2\u003e\n\u003cp\u003eThe Honda GX390 delivers 389cc of reliable power at 2,200 RPM. The cyclone air cleaner pre-separates large debris before it reaches the filter element — critical for a machine operating in constant sawdust and wood chip debris. Combined with the oil shutdown sensor, the engine is protected from the two most common causes of field failure: filter clogging and low oil pressure.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/Ajrvsu4E6fQ?si=eNtXO0OVjV-PXV7p\" title=\"YouTube video player\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eFree Shipping — No Sales Tax\u003c\/h2\u003e\n\u003cp\u003eShips free to the continental United States.
