Extra-long triple lips on the inner race team with a wide seal between the outer race and flange. Bearings are greasable for long life. Optional bearing-wear guards are recommended to reduce flange wear when you work in abrasive soil or need to disk deep. They are not recommended in rocky soil. Continuous-weld spools add protection.
Straight standards are massive.
This design directs thrust forces upward, prevents twisting of the gang tube when you encounter an obstacle in the field. Each standard clamps against the front and bottom walls of the gang tube. Gang angles are fixed for aggressive action. Experience shows these angles give you the best performance with these heavy disks in heavy-duty working conditions. A single crank lets you set depth from one easy-access location at the front of the disk.
