BOLTS WITH BRAINS
With a new design of leg and shear bolt assembly, the new B-series shear bolt ploughs bring many changes to improve operator friendliness and in-field durability.
In addition to the proven Trailer Transport System (TTS), and a hydraulic rear depth wheel with its clever pivot that allows the wheel to hang in its working position as the plough rotates above it, the B-series gets a four-way combination adjuster for skimmers, plus colour-coded hydraulic hose grips marked ‘+’ and ‘-’ highlighting oil flow. The revised leg is of solid design, and is sandwiched onto the plough beam using two plates, known as the Sharp Shear System. Using two plates delivers a clean shear, cutting the bolt into three pieces, rather than stretching it or causing leg deformation under extreme pressure. QUALIDISC 1100L The Qualidisc 1100L is one for smaller powered tractors, needing just 45hp to operate. Two rows of 520mm diameter discs with maintenance-free bearings are arranged at 25cm row spacings, and receive the Qualidisc’s proven individual disc/arm mounting and overload protection. Rear cage roller options are 400mm or 500mm diameter, with upward folding available, which places the roller over the rear disc gang, shortening the 710kg, 1.75m version for transport. A wider 2.25m model is available.
It also means that the amount of force needed to break the shear bolt is now higher, and is typically 5,000kg for the 3400B, compared to 4,500kg on the LO. Models include the 2300B in-furrow plough from 3-5 furrows with a headstock rated up to 250hp; the 3300B, an in-furrow plough that extends from 4-6 furrows with a headstock suited to tractors up to 350hp; and lastly, the 3400B and 3500B which can operate on-land and in-furrow, and both are 5-7 furrow builds, with a headstock capable of handling up to 380hp. All have 80cm under beam clearance, and can be specified with either 85cm or 100cm point-to-point.
