What to know before buying

The listing recommends sandy, loamy and relatively soft clay soils and cautions against soils with many rocks or dense roots. Customer feedback also reports mixed results in hard soil and concerns about shaft bending under torque.

Listing details to confirm

The title gives a 4"X24" size, while specifications separately confirm a 4-inch cutting diameter but do not independently confirm the 24-inch length. The claimed cutting angle is presented as “6E+1 degrees,” an unusual format, so its intended numeric value is unclear. The detail table lists high-strength steel and alloy, while feature text emphasizes steel and other promotional copy describes carbide blades. Confirm the selected listing's construction and dimensions if they are decisive.
