Sažetak
The encroachment of Eastern redcedar (ERC) (Juniperus virginiana L.) onto Great Plains
prairies has become a serious threat to ecosystem functioning and grazing productivity. The
uncontrolled spread of this invasive tree species has been called a »green glacier« converting
grasslands into closed canopy woodlands. A pasture tree cutting robot was developed using a
tracked Autonomous Ground Vehicle (AGV) equipped with a chainsaw bar to mitigate this
green glacier dilemma. The prototype was fitted with amperage and voltage sensors to measure
average power consumption and peak power requirements of tree cutting. It was evaluated on
ERC and Honeylocust trees up to 20 cm in diameter. Cutting energy and time were determined
to evaluate energy optimization and cutting time estimates. A pasture tree clearing energy
consumption of the developed prototype was estimated for selected tree density/hectare. The
prototype robot was successful in cutting down the intended size trees at a manageable power
usage.
