The dual-fuel BC1000XL is a 12-inch-capacity brush chipper that can run on gasoline or propane, and provides tree care contractors and rental business owners an alternative fuel option. The dual-fuel machine also includes the Vermeer-exclusive EcoIdle engine control system, which helps drive down the cost of operation while benefiting the environment. When the EcoIdle function is selected by the operator, the engine speed automatically lowers to a preset rpm after one or five minutes of inactivity to help reduce fuel consumption when not chipping material. The 12-inch by 17-inch infeed opening enables the chipper to better process difficult material. Control of the feed rollers is optimized with the four-position feed control bar. The bar is within reach of the operator, allowing him or her to activate the rollers from forward to reverse.
