Abstract: A sugar beet puller wheel set includes a pair of generally upright, spaced apart, symmetrically non-parallel puller wheels, rotatably disposed on axles attached to a frame and having a gap therebetween. A gap adjuster is associated with at least one of the puller wheels, and is configured to move the at least one puller wheel axially along the respective axle with axial rotation of the gap adjuster, allowing selective adjustment of the gap.

Abstract: A root crop harvester apparatus includes a transverse frame, supported to move above ground in a harvesting direction and oriented generally perpendicular to the harvesting direction. A plurality of pairs of generally upright, spaced apart puller wheels are connected to the transverse frame in a trailing orientation, having a substantially common rotational axis, and configured to contact the ground, each pair having a pinch point therebetween. The transverse frame is pivotal about an axis that is substantially aligned with the substantially common rotational axis, whereby rotation of the transverse frame collectively rotates all of the pairs of puller wheels about the common rotational axis and thereby adjusts a location of all of the pinch points with respect to the harvesting direction.
