This is a recent addition to the Bourne Sport fleet of machinery - a Dakota 310 Turf Tender. It is a compact machine for spreading various material - here you can see it used for top-dressing a park lawn in Camden. It can also be used, for example, for spreading rubber granules on artificial football pitches - an important part of keeping the synthetic grass in top shape.
This is a relatively new development - earlier machines of this kind are much bigger and have to be tractor-towed. This, pedestrian-guided machine is ideal for getting into areas with narrow access gates. It has an 11 hp Honda engine and the spreading width can be adjusted up to 6 metres.
There is a video of a Dakota 310 in motion here.
