4-wheel forestry and groundskeeping machine

The claim of the W100 was clear from the beginning: to be a 4-cylinder machine with absolutely impressive technology, yet light, small, compact and maneuverable. And those bold enough to set the limits in terms of pure hp discover entirely new, valuable vistas in other areas.

The W100 is compactly dimensioned and low weight on its own yet it comes with a modern Tier 4 final engine and SIB technology for shifting while in movement in the standard version. This makes the W100 more than just the ideal auxiliary cable machine in the 4-wheel range; it can also be delivered with many alternatives, as is the custom at Welte.
