Benefits of BUSA™ Medium Depth Soil Softener

01
01

Straight shank

BUSA’s Subsoilers are equipped with straight shank, which guarantee a uniform surface and a uniform soil cross-section.

One or two-row arrangement

The special two-beam frame and bracket of BUSA’s Subsoilers allow for one-row in-line or two-row arrangement according to agrotechnical needs

Carbide wear tip, Hardox tools

The carbide insert in the head, which is subjected to enormous stress, ensures long lifespan. This hard metal, which is produced by powder metallurgy, protects the most stressed part of the tool. The other wear parts of the subsoiler are made of Hardox wear-resistant steel.

Hydraulic adjustment

The Finishers of BUSA’s Ssubsoilers also perform a depth control function, which can be hydraulically adjusted even while in operation.

Extra strong frame

The goal in designing BUSA’s subsoiler was to make it indestructible. In the past, we encountered situations where our machines were pulled by a machine much larger than the prescribed one, or even by two tractors, which caused problems, but not for the new frame, which is oversized in both its design and material.

06

Uniform surface

A great advantage of BUSA’s Subsoilers is that they leave a uniform surface behind Since we do not unnecessarily disturb the soil, there is no need for a spiked roller, so our large-diameter finishers can do the job properly. With a front coulter disc, meadow loosening can be carried out, too.

History of the product family

What exactly is a LTH?

In the 2000s, the need arose to ensure that the loosener does not bring up “wild soil” in the clayey saline subsoil. This was the year when we introduced the straight backplate, which was widely used in the USA and marketed as a stand-alone product for many years. First we made machines with a V-arrangement, but later it was proven that the two-row arrangement achieves better slack with less traction.

A new direction is the in-line design, which can do a good job with a large knife spacing on dry soil. From there it was just a step to support strip-tillage, our 76.2 cm spacing, even with a staggered roller, supports direct seeding and strip-tillage well.

Why is it worth using the BUSA™ machines?

The BUSA Subsoilers are particularly effective in dry weather and on compacted soil. Where significant savings can be achieved by avoiding the creation of large clods, the handling of which would require significant effort later. Good aeration can also be achieved with less frequent spacing, resulting in greater area performance with less traction force.

Straight shank

The straight, narrow-profile shanks are made of high-strength spring steel, so we can ensure the proper strength with minimal resistance. Unlike curved…

forward-facing shanks, the straight design does not bring up the subsoil to the surface, but rather cuts the clods in half. The cutting edge can be easily and inexpensively replaced.

Adjustable arrangement

In a two-row arrangement, the subsoiler blades are arranged in two rows, so the blades in the second row already work in partially loosened soil. As a result, the soil resistance on the rear blades is lower, and the blade spacing can be smaller.

In the in-line arrangement, the blades are in one line, so their work is uniform and the surface disturbance is less. It raises the entire soil cross-section at once, making the subsoiler more effective. The frame construction of the machine is generally simpler. The greater soil resistance of the blades can be counterbalanced by greater blade spacing.

Easy depth adjustment

The working depth can be regulated by the tractor’s hitch system, the gauge wheel, or the finisher. The working depth can be adjusted between 200 mm and 600 mm.

Rollers developed and manufactured by BUSA

Large Spiral Angle Profile Roller

Angle Profile Large-Diameter Spiral Roller. Its structure is similar to the smaller version, but its larger diameter allows it to handle rougher surfaces and offers better clod-breaking capabilities due to the increased load.

Large T-roller

T-profiled heavy roller for soil compaction. Similar in design to the spiral angle profile roller. The T-profile spine provides effective clod-breaking and deep compaction. It works well on bumpy ground and its mud scrapers make it less prone to clogging. Read more Used as a closing roller for heavy field cultivators.

Disc Finisher

Autumn stubble maintenance can also be combined with subsoiling. Turns over the surface shallowly, mixing and smoothing it. It is not capable of depth limitation.

Frequently asked questions

Why is it good that BUSA Subsoilers have a straight shank?

These guarantee a uniform surface and a uniform soil cross-section. In the 2000s, the need arose to ensure that the loosener does not bring up “wild soil” in the clayey saline subsoil. This is when the straight shank, which was popular in the United States, was introduced and sold exclusively by us for a long time.

What kind of steel are BUSA's Subsoilers made of?

The carbide insert in the subsoiler head, which is subjected to enormous stress, ensures long lifespan. This hard metal, which is produced by powder metallurgy, protects the most stressed part of the tool. The other wear parts of the subsoiler are made of Hardox wear-resistant steel.

How to adjust the subsoiler working depth?

The working depth can be regulated by the tractor’s hitch system, the gauge wheel, or the finisher. The working depth can be adjusted hydraulically even while in operation using the finishers of BUSA’s Subsoilers.

How deep can BUSA Subsoilers work?

The working depth can be adjusted between 300 mm and 600 mm.

Can I use BUSA's Subsoiler for strip cultivation?

The in-line design with a 76.2 cm blade spacing can be used for strip cultivation. In this case, the subsoiler can be ordered with a special “interrupted” roller.

Why is the two-row arrangement good?

In a two-row arrangement, the subsoiler blades are arranged in two rows, so the blades in the second row already work in partially loosened soil. As a result, the soil resistance on the rear blades is lower, and the blade spacing can be smaller.

Why is the in-line design good?

In the in-line arrangement, the blades are in one line, so their work is uniform and the surface disturbance is less. It raises the entire soil cross-section at once, making the subsoiler more effective. The greater soil resistance of the blades can be counterbalanced by greater blade spacing.

Are the BUSA Subsoilers in-line or two-line?

The special two-beam frame and bracket of BUSA’s Subsoilers allow for one-row in-line or two-row arrangement according to agrotechnical needs

What type of tools are the BUSA Subsoilers equipped with?

In its standard configuration, the implement comes equipped with winged subsoiler tools. The size of the wings and the angle of the tools are ideal for medium-bound soil, and for very compacted soils, a version without wings can be chosen. The hardened wear tip of the tool is replaceable, as are the attachable wing blades.

How are the BUSA Subsoilers protected against overload?

The cultivator elements are equipped with shear bolt protection.
