BCS and Grillo Rear-tine Tillers

Tillers, with their horizontally-mounted shafts and vertical tilling action, are the most widespread tillage tool for small-scale farming and gardening: simple, versatile, low cost, and effective. The Grillo Company has been building rear-tine tillage equipment since the early 1950’s. Through a technology-sharing venture with BCS which lasted from roughly the late 1960’s to the early 1980’s, BCS acquired rear-tine tiller technology (the first BCS-branded tillers were produced around 1970). Both companies’ tiller implements currently feature 290 rpm tine speed (with engine at maximum rpm), hardened-steel ring and pinion gear drive and ball bearing supported shafts in an oil bath. Both units use a wedge-shaped “middlebuster” (BCS calls theirs a “Planar wedge”) which has 3 functions: 1) Depth control; 2) completely breaks out center strip of untilled soil under gearbox; 3) helps hold tractor in place in hard soils. BCS planar wedge adjusts to 4 depth positions; Grillo adjusts to 6 positions.

Grillo tillers also feature a “Helix” type spiral time pattern (with Bolo style tines) for a smoother tilling action. Both brands will leave up to 8” deep worked soil. Tillers can be used for primary cultivation but can over-pulverize the soil, resulting in degraded soil structure. Caution has to be taken not to over-till. Tillers are best used for secondary tillage, seedbed prep, mixing fertilizer and crop residues into the soil (provided they are not too long and fibrous, in which case they will tend to wrap around the tine shaft), shallow weed control and inter-season work. A Hiller/furrower accessory can be quickly attached behind all tillers to make furrows or push soil out for hilling or ridging. We also offer a depth-control wheel which allows more precise-depth shallow tillage for weed control, adjustable from 0” to 3” (See our Accessories page, Implement Accessories section for more details…also priced below) AND we now offer full-width Depth-Roller systems that not only regulate tilling depth very precisely, but also “tamp” the bed for better results with precision seeding equipment.

NEW FOR 2023: We now offer a Counter-Rotating tiller implement built by Grillo, which fits the Grillo walking tractors 11hp and up. Counter-Rotating tillers rotate the opposite direction of the tractor drive wheels, so they offer better control and faster penetration when “breaking sod” or working very hard soil.
Due to the fact that a counter-rotating tiller discharges the tilled soil to the FRONT, they can, if used in soils with a lot of fibrous organic material present, form a build-up of fibrous material in front of the tiller, possibly causing the drive wheels of the tractor to lose traction (you may have to lift the tiller up for a second or two to get past the “build-up”). If the soil is “clean” of fibrous material, the soil will “flow” out from the front of the tiller and form a small “ridge” to each side, while leaving the bed behind the tiller slightly depressed. Therefore, they are not terribly popular for all Agricultural applications (not good for seedbed prep or light weeding, for example), but they are GREAT for Landscaping / Lawn renovation projects when you need to bust up the soil fast. Standard width is 27”; tilling width is adjustable down to 22”, 19” or 15”. (NOTE: Our “TDS” roller system does NOT fit this tiller!)
