A hydrostatic drive walks the grinder to the stump, around the yard and back up the ramp under its own power, so the operator is not muscling 500 pounds of steel across a lawn between cuts. On a route with six or eight stumps, that is the difference between a full crew day and a short one.\u003c\/p\u003e\u003cp\u003ePower comes from a 20 HP Honda GX630 electric-start V-twin turning a 14-inch cutter wheel through a direct belt drive. Cutting capacity is 24 inches above grade and 18 inches below — deeper and taller than the walk-behind 620, which is what makes this the machine for removals where the stump is oversized or the customer wants the ground clear for replanting.\u003c\/p\u003e\u003cp\u003eAll-terrain tires keep the machine tracking straight on soft ground and slopes, the handlebar adjusts through five positions, and the side-discharge frame throws chips clear of the cut. Greenteeth 700 Series teeth come standard: rotate each tooth 120 degrees for a fresh edge, three edges per tooth before replacement.\u003c\/p\u003e\u003ch3\u003eKey Features \u0026amp; Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHydrostatic self-propelled drive\u003c\/strong\u003e – the machine moves itself between cuts and onto the trailer; no pushing, no wrestling on slopes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHonda GX630 electric start\u003c\/strong\u003e – 688cc commercial V-twin, turn-key starting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e24 in. above \/ 18 in. below grade\u003c\/strong\u003e – deeper and taller reach than the walk-behind models for oversized removals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-terrain tires\u003c\/strong\u003e – 16 x 6.50-8 in. tires keep the unit on track over soft ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGreenteeth 700 Series teeth (8)\u003c\/strong\u003e – three indexable cutting edges per tooth, concave dish shears rather than shreds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5-position handlebar\u003c\/strong\u003e – comfortable working height for any operator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide discharge frame\u003c\/strong\u003e – keeps chips out of the cut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect belt drive\u003c\/strong\u003e – 4-groove power band with idler bearing belt tensioners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecifications\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eEquipment Type\u003c\/td\u003e\n\u003ctd\u003eStump Grinder (Self-Propelled)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrive System\u003c\/td\u003e\n\u003ctd\u003eHydrostatic self-propelled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEngine\u003c\/td\u003e\n\u003ctd\u003eHonda GX630, 688cc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStarter\u003c\/td\u003e\n\u003ctd\u003eElectric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCutter Wheel\u003c\/td\u003e\n\u003ctd\u003e14 in.
