One machine setup – fully suited for mowing, collecting, and transporting on the most sensitive terrain

This unique tracked machine combination was entirely developed and built in-house by De Vries Cornjum Machinebouw BV. It is specifically designed for use in wet nature areas, where low ground pressure and maximum reliability are critical. This combination has been used professionally for years and is now offered in neat, immediately usable condition.

The setup includes:
– A DVC Wetland tracked tractor type Ijsvogel
– A fully driven tracked loader wagon type 7.36
– A custom-built hydraulic disc mower with swath former
– A hydraulically driven Votex flail mower

The combination is sold as a whole. Viewing and test driving is possible by appointment at our yard in Cornjum.

DVC Wetland tracked tractor ‘Ijsvogel’

At the heart of the machine is a robust tracked tractor with a 160 hp 6-cylinder diesel engine, hydrostatically driven in all functions. The drive system, running gear and hydraulics are all independently operated through separate circuits, ensuring reliable performance, easy operation and full control – even in demanding conditions.

Features:
– Fully built by De Vries Cornjum BV
– 160 hp 6-cylinder diesel engine
– Hydrostatic drive on all systems
– Suspension with oscillating axles on two main axles
– 10 solid rubber wheels
– DVC self-built wetland tracks with rounded steel tube profiles
– Profiles with stainless wear plates and hardfaced outer layer
– Central automatic lubrication system for all rotating parts
– Front-mounted DVC collision and tilt frame for mower attachment
– Steering via Pistenbully wheel, hydraulics controlled by joystick console
– Rear quick coupling and hydraulic connectors for fast switching of implements

Thanks to the intelligent coupling system, the machine can be quickly disconnected and reassigned to another implement – with minimal hassle and no downtime.

Tracked loader wagon type 7.36 – powered, guided, built for wetlands
