A pull-type crop engaging machine for towed movement by a tractor comprising: a frame mounted on field ground wheels (17, 18) spaced in a transverse direction for forward movement in a forward direction generally at right angles to the transverse direction during field operation across ground carrying a crop; a crop engaging system mounted across a front of the frame so that the frame carries the crop engaging system in the forward direction into the crop; a hitch arm extending from the frame to a forward end of the hitch arm arranged for attachment to a hitch connector of a tractor by which the frame is towed in the forward direction across the ground while running on the ground wheels (17, 18); a coupling for connecting the forward end of the hitch arm to a hitch connector of the tractor; and a transport assembly attached to the frame for transporting the frame and the crop engaging system carried thereon in the transverse direction towed by the tractor through the hitch arm; the hitch arm being movable so that in the field position the hitch arm extends from the frame generally forwardly for towing the crop engaging machine in the forward direction and in the transport position the hitch arm extends from one end of the frame generally in the transverse direction for towing the machine in the transverse direction; the transport assembly comprising: at least one transport ground wheel attached to the frame for engaging the ground and supporting the frame during transport; said least one transport ground wheel being movable between a first position in which the transport ground wheel is raised from the ground for field operation and a second transport position in which said least one transport ground wheel is in contact with the ground with the field ground wheels lifted from the ground; CHARACTERIZED IN THAT the transport assembly is arranged to raise the frame and the crop engaging system carried thereby to a height in which said at least one transport ground wheel passes underneath the crop engaging system to the second transport position. a frame mounted on field ground wheels (17, 18) spaced in a transverse direction for forward movement in a forward direction generally at right angles to the transverse direction during field operation across ground carrying a crop; a crop engaging system mounted across a front of the frame so that the frame carries the crop engaging system in the forward direction into the crop; a hitch arm extending from the frame to a forward end of the hitch arm arranged for attachment to a hitch connector of a tractor by which the frame is towed in the forward direction across the ground while running on the ground wheels (17, 18); a coupling for connecting the forward end of the hitch arm to a hitch connector of the tractor; and a transport assembly attached to the frame for transporting the frame and the crop engaging system carried thereon in the transverse direction towed by the tractor through the hitch arm; the hitch arm being movable so that in the field position the hitch arm extends from the frame generally forwardly for towing the crop engaging machine in the forward direction and in the transport position the hitch arm extends from one end of the frame generally in the transverse direction for towing the machine in the transverse direction; the transport assembly comprising: at least one transport ground wheel attached to the frame for engaging the ground and supporting the frame during transport; said least one transport ground wheel being movable between a first position in which the transport ground wheel is raised from the ground for field operation and a second transport position in which said least one transport ground wheel is in contact with the ground with the field ground wheels lifted from the ground; CHARACTERIZED IN THAT the transport assembly is arranged to raise the frame and the crop engaging system carried thereby to a height in which said at least one transport ground wheel passes underneath the crop engaging system to the second transport position. at least one transport ground wheel attached to the frame for engaging the ground and supporting the frame during transport; said least one transport ground wheel being movable between a first position in which the transport ground wheel is raised from the ground for field operation and a second transport position in which said least one transport ground wheel is in contact with the ground with the field ground wheels lifted from the ground; CHARACTERIZED IN THAT the transport assembly is arranged to raise the frame and the crop engaging system carried thereby to a height in which said at least one transport ground wheel passes underneath the crop engaging system to the second transport position.
