HarvaDig – Excavator Forestry Conversion
An Excavator based system, converting standard machines into forestry harvesting machines, whilst keeping their potential for other more typical excavator tasks.
Although excavator based harvesters have been on the go for years now, the HarvaDig name and concept began serious development by Jas P Wilson in 2009. After receiving a request for a simple and relatively small excavator based machine, we started to investigate different excavator and harvesting head combinations.
The client also asked about the possibility of a demountable head which would allow the excavator to carry out normal digger work or work with other attachments. As the harvester would be working in tight areas and thinnings we realised a zero tail swing would be the preferred option. A 14 tonne machine was purchased and fitted up with a Keto 150LD harvesting head for trials.
