Abstract

fetched live from OpenAlex

In 2006, a willow harvester was developed with a 1.97-m wide four-saw cutter and a 1.55-m wide rotary shredder placed in front of an agricultural round baler. The header worked well in level plantations and left a clean-cut stump. However, it was not designed to operate on uneven land where rocks and soil might cause saw blade malfunction. For this reason, a second more robust header was developed in 2007 to harvest natural brushes on fallow land. The new header was a 2.30-m wide flail shredder that both cut and conditioned the woody brush before ejecting it into the baler. It was evaluated in two field trials in eastern Canada. On a fallow and poorly drained land, the shredder header-baler harvested natural alder shrubs at an average rate of 4 t wet matter (WM)/h. In a level willow plantation, the shredder header-baler worked up to 12 t WM/h, compared to 8 t WM/h with the original four-saw header-baler. The bales typically weighed 400 kg, were 1.4 m in diameter and 1.2 m wide; they had a wet density of 220 kg/m at 50% moisture on a wet basis. The two headers can be adapted to the same round baler and offer a versatile alternative to harvest either wild brushes or planted woody crops. The technology may improve land management and provide a new source of otherwise neglected biomass.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
