Abstract: Plant scanning vehicles (10) including, but not limited to, plant scanning vehicles for use in field-based phenotyping. There is a central body (16); three or more legs (15) extending from the central body (16) to support a wheel (13) on each leg (15); wherein the three or more legs (15) are mounted to the central body (16) rotatably about a respective vertical axis (95) to allow adjustment of a track width W of the vehicle by rotating the legs wherein the legs are mechanically coupled to transmit rotation between the legs about their respective vertical axes and the central body (16) or the three or more legs (13) are configured to support a sensor (47) to scan plants.

Abstract: A tree harvester, suitable for harvesting small trees in row(s) as a source of biomass, has a harvesting head with a chipper drum and complementary anvil. A pick-up front has at least one spiral and guide member, such as a guide rail or counter-rotating spiral, to maintain a tree in a substantially vertical position when, and after, its stem is cut by a base cutter. The pick-up front has a support plate or conveyor, which co-operates with the at least one spiral or guide member pair, to convey the tree to a location about the chipper drum, for engagement by at least one pair of nip rollers above the chipper drum, while maintaining the tree in the substantially vertical position. The, or each, pair of nip rollers feeds the tree downwardly (and rearwardly) to the chipper drum, while still maintaining the tree in the substantially vertical position, for conversion to biomass, such as woodchips.

Abstract: A ground engaging apparatus (10) has a support plate (50) pivotally attached to a frame (100); a pair of arms (30, 40) interconnecting the support plate (50) and a shank support (60), which supports a shank (70) and ground follower (90) and first and second biasing rams or springs (200, 300), to maintain the ground follower (90); against the ground (91) but allow controlled break out of a ground opening, or tillage, tool (81) if an obstruction is engaged.
