The M400 pro-chipper has a powerful 20Hp 2 cylinder Honda GX engine equipped with an electrical start. Due to the big wheels at the front and the pivoting caster wheels at the rear with a good movement and a small width of 73cm, the M400 can be easily used in all parts of the garden. The separate metal jerrycan avoids fire danger upon filling petrol, focussing again on the safety standard of Jo Beau.

The Jo Beau® drum technology™ guarantees that branches with a diameter of 10 to 12cm – depending on the wood type – can be perfectly converted into high quality wood chips. The surprisingly wide inlet opening of 67cm was designed for an ever bigger volume side branches.
The different options such as: detachable piece high rotating discharge pipe, leakage free wheels at the frond and the rear, make the M400 very appropriate for gardeners, arborists and rental companies.

All Jo Beau machines are built according to the valid European guidelines and have a CE-certificate. All machines are supplied with manuals and parts list.
