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, with an easily-adjustable amount of “swing” in the hitch for “steerability”. (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 brands other than Aldo Biagioli Cultivators, due to this problem.)

NEW! Trailing Disc Gauge Wheels

Trailing Disc Gauge Wheel attached
to Aldo Biagioli ET-type Cultivator

Highslide JS

Kit includes horizontal bar,
vertical shank with wheel,
and clamps

Another innovation from Earth Tools: The “Trailing” gauge wheel system puts the gauge wheels BEHiND the cultivator bar, for an “extended wheel-base” to make cultivators more precise, easier to guide, AND KEEPS THE WHEELS OUT OF THE WAY OF THE CULTIVATION TOOLS. Even better, the disc-type wheels cut into the ground slightly (although a “limiter ring” welded onto each disc keeps them from sinking in too far) for even better “train-track” precision control. One kit includes 2 Horizontal bars, 2 Vertical shanks with wheels, and all clamps. (Items available separately as well…call for prices) PRICES AT BOTTOM OF THIS PAGE, WITH ALL OTHER PRICES.

NEW! “Hoss” Tool Adapters

Hoss Tool Adapter "shank" and Wheel hoe

We now offer an adaption system that allows you to attach the popular “Hoss” brand Wheel-hoe tools to our cultivators. It consists of 2 parts: A “shank” with brackets to attach to a Hoss Wheel-Hoe frame, and the [green] wheel-hoe frame itself…We sell these as a “kit” (1 shank & 1 frame). Once you have this kit, ANY of the Hoss tools that will mount to a Hoss Wheel Hoe will mount up. Since it utilizes an actual Wheel Hoe frame, you can take advantage of the same versatility that you would have on a Hoss Wheel Hoe…for example: Mounting both right and left hilling plows (or cultivation sweeps) on the same frame. You can fit as many of the kits on a tool bar as the bar width allows. (Scroll down to see prices)

See our Garden tool section for a list of the various tools that Hoss offers.

FOR MOST EFFECTIVE USE, THIS IMPLEMENT TYPE MAY REQUIRE WHEEL WEIGHTS ON TRACTOR. 4 x 10 x 18” MINIMUM wheel size recommended; larger wheels better!

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.)
