Aggressive Disc Angle
The U671 pro features an aggressive disc angle to allow for maximum penetration into hard soils. It’s solid engineering and strong construction allows it to perform well in challenging conditions.Two angles on the disc for the twist and the layover means these two-work hand in hand to allow for excellent penetration into hard ground and can equally turn over the soil to incorporate stubble.
Two Point Tow Hitch
The semi mounted draw bar enables easy connection and due to the pivot point being set further away from the tractor gives you maximum turning performance.
The U671 is fitted with highest quality 50mm LongLife rubber suspension, allowing it the machine to withstand vibrations and shocks from hard soil and small obstacles in the field.
The LongLife shock absorbers are used as standard in U 652, U 665 and U 671 disc harrows and as an option at U 693
Benefits of using the LongLife rubber: – low permanent deformation, the shock absorber quickly returns to the starting position after loading – high elasticity of the shock absorber can transfer critical loads without risk of tearing – extended operating time of the shock absorber – reliability that every time we purchase repeatable quality (3.1 certificate)
The dual PFC ring roller breaks down cloddy soil leaving a smooth even finish, the rocker suspension helps the machine travel on uneven ground.
