Rigid Tool Bar With Triple Tubes

Standard Features on Rigid Tool Bars

• All frames are constructed from A 500 Grade B. This heavy wall tube takes a load without bending or breaking. Tube size varies from 4x4x1/4” wall, 4x4x3/8” wall, 4x7x3/8” wall and even 5x7x1/2” wall, 7x7x3/8” and 1/2” wall on single bars.
• Design feature with upper mast turned on the diamond increases structural strength by 33%.
• One-piece stringer plates (braces) are cut from 5/8” solid plate steel.
• All joints are securely welded using pulse arc technology to minimize cracks near welds.
• We will custom build any type of tool bar to your specification.

Superbar II Tool Bars (Triple Bar & Double Bar) are constructed with a diamond mast, which distributes load and stress between lower tubes and stiffens the bar. For bars subjected to unusual load or stress, heavy duty options are available in both the triple and double bar designs. On the heavy duty tool bars, 4 x 4 x 3/8” tube is substituted for 1/4” tube on all lower bars for extra strength. Strap steel is formed to give a 360 degree weld around lower bars.

All-purposed triple bars are spaced for a variety of functions: Cultivators or planters, ripper plows, chisel plows and many others.
