We identified many problems and limitations of existing hoggers.
We questioned what users required.
From this, we found the principle issues were :

- high fuel consumption per ton output,
- high running costs,
- easily damaged, especially from foreign objects;
- long down-times required for repairs or constant routine maintenance;
- they could be expensive to repair, often exotic steel alloys used;
- they could be dangerous to operate;
- low quality hog fuel produced, with excessive fines and dirt;
- some prone to jamming, especially by fibrous materials;
- some very inefficient, if not loaded with a very specific sized product;
- post-screening of hog fuel was required;
- outfeed height too low, can not load hog fuel directly into a trailer or hopper;

As a result, we designed a hogger to give our customers what they wanted.
