“F” Series spreaders are a range of linkage mounted spreaders incorporating a belt feed system, available from standard wheel drive machines through to variable rate including section control.
A commercial fertiliser spreader with high precision
The standard F2 model is equipped with simple and sturdy mechanical and driving-dependent dosage. In practice, this means that the application rate is continuously and automatically adapted to the forward speed without using electronics. With the help of the hydraulically operated dosing wheel, the tractor’s PTO need not be switched on and off when turning in the headland, which is very user-friendly.
The F2 is also supplied as standard with “A” discs for spreading commercial fertiliser, a SPC4500-1 spreader unit with 24-36 metre edge gear for headland spreading. Alternatively, 12–28 meter headland gear can be selected instead.
With hopper sizes of 1,500 to 4,000 litres and working widths from 12 to 36 metres, the F2 will meet most needs.
Simplicity is incorporated into the F2. Spreading blades should not be changed or adjusted regardless of whether they spread over 12 or 36 metres.
The dosage takes place with a belt, which means that there is only one dosage table for all fertilisers that are spread.
Bredal’s F2 models are available with hoppers either painted red or stainless steel.
Fertilizer spreader for a tractor
Bredal’s F4 is constructed with two separately controlled belts so it is possible to spread different amounts on the right and left sides. The belts are driven by an oil motor which is regulated via a proportional valve.
The down position is controlled by two electric motors and is operated automatically by the spreader’s computer. When a working width is selected, the downchutes automatically adjust to this. On the lift-mounted fertilizer spreader, the F4, the downward position is controlled individually in the right and left side, this is used inter alia. for edge spreading.
In the downlink control software, an automatic flow correction is built-in, so that the down position automatically adapts to the amount of the current seed. This means in practice that no changes occur in the spreading pattern, regardless of whether the run involves a small or large quantity.
The downstream electric motors are made of plastic and stainless steel and are well protected by shielding.
All movable parts of the tailgate are made of plastic or stainless steel, which in practice means minimal maintenance.
