Description

The B31-110 with its width of only 74cm is the most compact, full automatic stump grinder in the market. With the wide caterpillar tracks and the big manoeuvrability the B31 works without problems on rough ground and slopes. The powerful 2 cylinder Vanguard petrol engine with 31 Hp grinds in a never seen time a stump with a width of 110cm and a deepness of 50cm. The grinding arm is moved full automatically or manually by means of hydraulics and can be put completely straight for transport. The grinding wheel is driven by double industrial V-belts.
The following performance examples (average values):
› ø300mm: 7 min
› ø600mm: 18 min
› ø1000mm: 60 minThe 12 piece Greenteeth® teeth can be rotated 3 x (120°) without any problem and can be reground afterwards. The separate metal jerrycan avoids fire danger when filling petrol, once more highlighting the safety standard of Jo Beau! With other words: the B31-110 fulfils again the requirements of the professional gardener, arborist and rental company working also on places with difficult access.
