Aldo Biagioli Tool Bar / Cultivators

ET-5 with tool carrier & drawbar

Constructed by Aldo Biagioli of Italy, these universal tools are available in 4 configurations and feature clamp-on shanks with standard reversible 1½” wide chisels. The working angle of the tool is controlled by the adjustment on the Tool Carrier (see below), and the overall penetration depth is controlled both by this angle adjustment AND the TWO removable/adjustable caster wheels that all of this brand of cultivators come with (other cultivators on the market have only a SINGLE depth wheel, which is problematic: With only one depth wheel, when one of the tractor wheels goes over a hump or into a depression, the shanks on one side of the cultivator lean to one side and “dig in” more, causing the tractor to veer in that direction).

Also, the Aldo Biagioli design allows the standard 2” wide chisels to be easily removed with a single bolt, and the curved OR straight shanks will accept “V-sweeps”, which, when the angle of the tool carrier is adjusted so that the sweeps lay “flat” on the ground, are great for weed control, slicing just below the surface. These sweeps are available from us, or at most Farm Supply stores. Outfitted correctly (and with exact row spacing!), several rows of crops can be cultivated between simultaneously, as the tractor can straddle 6” – 7” tall plants (with tall enough tires).

Various V-sweep sizes for the Aldo Cultivators

Aldo Tool Bar with Shank-Mount Furrowers installed

The completely modular design of the Aldo Biagioli cultivators allow the clamps and shanks to be adjusted side-to-side or up-and-down on the frame. Shanks can also be removed, or, if you want to add more, shanks and clamps are available separately. Frame can be adjusted to free float (oscillate) or can be locked with plane of the tractor axle. Straight-bar styles (ET-3, 5 and 6) can have shank-mount Furrowers attached to the frame instead of shanks; and ALL styles accept Disk Hillers as well (see Double Ridger/Bedshaper tab above). Drawbar (shown below) attaches to tractor at PTO mounting, for a solid and sturdy mount. (Other brands of cultivators on the market attach at the tractor “tow hitch” mounting, which, in our testing, has proven to be a poor place to mount such an implement, as it is very hard to control the “side-swing” of the tool… the “limiter” bolts supplied on the tow-hitch type of tool carrier simply have very little surface to brace against, and they deform easily. We have chosen NOT to carry these other brands, due to this problem.)

THIS TOOL REQUIRES THE DRAWBAR AND TOOL CARRIER SHOWN BELOW!! Angle of frame relative to tractor adjusted by T-handle crank on Tool Carrier…this allows “attack” angle of the tool to be adjusted. (NOTE: If purchasing multiple implements made by Aldo Biagioli, ONLY ONE Tool Carrier and Drawbar need to be purchased! Tool carrier and Drawbar change quickly from implement to implement with just one pin.)
