A new range of fully-mounted shear bolt ploughs is being launched by Kverneland. Models benefit from an all-new leg and shear bolt protection system to handle up to 5,000kg before the bolt shears, compared to 4,500kg on previous models.
Models include the 2300B from 3-5 furrows, the 3300B from 4-6 furrows, plus the 3400B and 3500B available in 5-7 furrow formats. The 3500B is an Isobus-equipped i-Plough version.
While the 2300B and 3300B are in-furrow only for tractors up to 250hp and 330hp respectively, the larger 3400B and 3500B can be used on-land or in-furrow, with tractors up to 380hp. Variomat hydraulic furrow width adjustment is part of the specification, along with 85cm and 100cm point-to-point clearances, and an 80cm under-beam clearance.
Kverneland’s new Sharp Shear System uses a solid plough leg design sandwiched between two steel plates. The leg is secured in work with a precision engineered shear bolt, which carries shallow grooves along the shear line.
