Usually another person must hold down the tree to the right side of the person operating the brush cutter. Material less than 2 inches in diameter can be manually cut with long-handled lopping shears. When cutting the biomass, leave a stump at least 6 inches tall if you will be cultivating the sprout growth. Naturally, coppice growth will not do well if it must compete for light with established trees. Soon after it is cut, biomass should be chipped and large diameter fuelwood should be split to fit your stove.
Wood is easier to split when it is green.
If you will be burning chipped biofuel in a modified grain drier or space heater, run the wood through a standard drum chipper. Hydraulic chippers are considerably more expensive but produce a more uniform chip than other chippers. Large leasing companies have chippers available for rent. While wood is drying, it should be stored outdoors under a raised cover that sheds precipitation but allows for plenty of air circulation. Fuelwood may take six to nine months to air-dry to the desired 20 to 25 percent moisture content.
