Performance of two shear heads for harvesting biomass in hardwood stands in France

The two shear heads were more productive at high forest than at coppice. The stand type had a significant effect only on the C360's productivity. At high forest sites with small diameter trees, the C360 was 11.8% more productive than the S350. However, at coppice site, the S350 was 15% more productive than the C360 for harvesting big clumps. Results showed that working in coppice forest requires a head that must be very powerful and have a wide opening.
