Hydraulic Spring Adjustment

This feature provides easy and simple setting of the ground pressure. For greater operator comfort, ground pressure of the large suspension spring is set hydraulically from the tractor cab. On the hydraulic version the tension on the large suspension spring, which controls the ground pressure, is adjusted hydraulically, to increase or lower pressure. The chosen ground pressure level is conveniently registered from the easy-to-read scale.

Centre Suspension

The centre pivot suspension provides an even weight distribution of the EXTRΔ 300 series, 400H, 624T and 628T and a uniform ground pressure over the complete working width, ensuring good ground contour following.

The mowing units are suspended in the centre of gravity. This design provides a constant, faster and more precise adaptation to ground contours.

The benefit is less skid wear, optimum protection of the stubble and less fuel consupmtion

Protection of Cutterbar

  • To offer maximum protection of the cutterbar, these machines are fitted with the well-known Vicon BreakAway solution.
  • When encountering an obstacle, the BreakAway will swing the machine backwards and over the obstacle, returning it to the original working position once the obstacle has been passed

Vertical Transport Solution

  • EXTRΔ 300 series, 624T and 628T are folded into a vertical transport position up to 125°.
  • The low gravity point during transport, with the weight of the mower close to the tractor, provides an excellent weight distribution, even during high speed road transport, and the machine is fixed by the hydraulic lifting arm.
  • In addition transport height is limited, so passing through narrow gateways or under bridges is not a problem.
  • Another benefit is that the hydraulic cylinder also supports quick lifting of the mower from working to headland position.

Two Speed Gearbox

  • The machines also offer a large degree of operating adaptability, as they are factory fitted with the option of being operated with either 540 or 1000 rpm.
  • It requires no additional accessory. All that is needed is to turn the main gearbox on the suspension 180°.
