Stump Grinder Built For Garden Tractor MISCELLANEOUS EQUIPMENT Miscellaneous “I have a nice shop so rather than spend $2 500 on a stump grinder for my tractor I decided to make one myself ” says North Dakota inventor Evan Waa The machine he built resembles a commercial model made by Woodland Mills a Canadian company “My grinder mounts on the 3-pt hitch of my open station Kubota BX2200 a smaller garden tractor that I can maneuver in and around trees ” Waa says The tractor has 22 hp and a 540 pto Waa used 2 ft of 3-in square steel tubing to build the frame for his grinder The 24-in dia cutting disk is made of 3/4-in steel fabricated by a metal shop The disk is bolted to a 1 3/8-in 6-spline drive shaft that connects directly to the tractor with a flexible slip-clutch style pto shaft Waa used his plasma cutter to fabricate the body pieces out of 1/4-in thick sheet steel that came from metal workbenches damaged in a fire “I pre-cut slots so the pieces connect front and rear like a tongue and groove arrangement I put a flex joint in the middle of the grinder so I can slow down creep ahead and back up while the wheel is turning ” he says The pto shaft extends out as the grinder flexes Waa runs the grinder with his tractor at half throttle “The grinder easily cuts an inch to an inch and a half at a time using 34 teeth mounted on the cutting disk The teeth cost $6 60 each but they’re carbide tipped and do an excellent job of cutting ” Waa says “I’ve probably cut out 30 or more stumps with the grinder without any problems ” Waa adds “At first I went too fast over some stumps and killed the tractor so operating it took a little getting used to I set up a piece of snow fence on the side of the machine to keep the chips in a pile so they’re easier to clean up ” Contact: FARM SHOW Followup Evan Waa Prosper N D evanwaa@gmail com
