Rototillers are generally considered secondary tillage implements, something used after plowing, but you can use them for primary tillage in lighter soils than for heavy plowing. The earliest rototillers were massive steam- powered machines, but most are now the compact variety used by home gardeners who rent them. Towing one with a 3-point hitch behind a tractor permits a far larger rototiller resulting in cultivating much greater acreage than possible with the garden variety. With welding skills and sufficient mechanical aptitude, you can craft a 3-point rototiller.
Things You'll Need
- 5 foot long steel shaft 1 7/8 inch in diameter
- 3 steel collars 18 inches in length and three inches in diameter
- 3 steel discs 1 inch thick and 9 inches in diameter
- 1/2 inch thick bar steel
- 1/8 inch thick steel plate
- 2 wheel assemblies
- small gasoline engine
- transmission gear unit
Use a 5-foot long steel shaft 1 7/8 in diameter of high strength steel. Weld three collars 18 inches in length and 3 inches wide equidistant from one another onto the shaft. Leave 16 inches free on either side of the shaft from the outer side of the collar on the right and left end. Center discs of 1-inch thick steel over each collar and weld them into place.
Create 36 L-shaped units from 1/2 thick bar steel. They should end up 4 x 2 inches. These will function as the rototiller's tines.
Weld the long ends of the 12 tines to each disc, spacing them evenly all around. Weld two inches to the disc with the remaining two inches sticking straight out.
Frame the unit with 1/8 plate steel. Allow enough room on each end to mount a wheel assembly and enough on one end to hold a small gasoline engine and transmission gear unit. Bolt a three-point hitch assembly to the front of the frame.
