No waste with this feature.
The optional ‘sidelift’ feature uses hydraulics to raise and move the wagon body to the side allowing accurate delivery into feed troughs or bins without damage to the wagon, tractor or the bins. It is available on RF9, RF11 and RF13 models only.
At full height, the delivery belt is 1.2m from the ground and extends a maximum 0.7m past the tyres, allowing virtually waste-free delivery into feed bins up to 1.0m high. When the machine is lowered, it has the same lower centre of gravity and loading height as a standard model.
One double-acting hydraulic bank is all that is required to operate this feature.
The conveyor autoshift feature may also be of interest to you.
