The ProSilva S4 is a 4-wheel drive all-rounder with excellent reliability and safety. The harvester has an enhanced heavy duty front frame structure compared to the S3 4×4 so it can be equipped with larger cranes and harvester heads.
The S4’s engine drives twin hydraulic pumps that allow the crane and harvester head to be used at the same time. Several functions can be operated simultaneously with continuous hydraulic oil flow.
Operator comfort and wellbeing have always been a key design principle for us, so the S4 operator cabin is spacious and ergonomic. The rear wheels can be equipped with pendulum arms which automatically self-level the machine frame laterally. The pendulum arms ensure safety and operating stability as well as comfort. The operator cabin also levels itself backwards and forwards in a longitudinal direction. All these functions, combined with the cabin’s automatic horizontal rotation, makes ProSilva the most comfortable forest machine on the market.
The 4×4 wheel configuration with large diameter wheels and high traction drive system turns steep slopes and deep snow from a risk into an opportunity. And if you need even more traction the wheels can be replaced with tracks.
