A swing leg assembly, coupled to a paving machine for spreading, leveling and finishing concrete, includes a pivotable swing leg coupled to the paving machine. The swing leg may pivot between multiple angular orientations relative to the paving machine. A jacking column is coupled to the swing leg, and a crawler track is coupled to the jacking column. A slew drive coupled to the jacking column and crawler track rotates the crawler track relative to the jacking column between multiple angular orientations. A processor using sensors determines the angular positions of the swing leg and crawler track, and in response to determining a change in angular orientation of the swing leg controls the slew drive to cause the crawler track to rotate relative to the jacking column.

A leg assembly includes a guide tube, a power drive coupled to a flange of the guide tube, a steering ring coupled to the power drive, a tube weldment coupled to the steering ring, and a hydraulic actuator coupled within the guide tube and within the tube weldment. The power drive includes a slew drive or a hydraulic cylinder steering assembly. The tube weldment is translated through the power drive by the actuator. The steering ring includes one or more pistons by which relative rotational movements may be imparted to the tube weldment by a socketing action. The steering ring is rotated by the power drive. Thus, the guide tube may be rotated relative to the tube weldment.

A soil processing machine includes a machine frame with two longitudinal beams substantially extending in the longitudinal direction of the machine and two transverse beams substantially extending transverse to the longitudinal beams. A soil-processing roller is supported in the longitudinal direction between the transverse beams on the longitudinal beams so that it can rotate about an axis of rotation of the roller. A coupling arrangement is provided on the machine frame for attaching the machine frame to a further machine frame of the soil-processing machine or to a further machine. A lifting/supporting arrangement is provided on the machine frame for lifting and/or supporting the machine frame in relation to the ground. One of the transverse beams is supported on the two longitudinal beams so that it can rotate about a swivel axis substantially parallel to an axis of rotation of the roller.

A track drive for outdoor power equipment has a support frame with a centerline and a hub bearing attached to the support frame. A drive sprocket having a nesting interior half and exterior half is attached to the hub bearing, which enables the drive sprocket to rotate relative to the support frame. The drive sprocket is attached to an associated drive hub of a piece of outdoor power equipment. Drive sprocket teeth are spaced radially about the drive sprocket, with a first set of drive teeth attached to the interior half sprocket and located on an interior side of the support frame. A second set of drive teeth are attached to the exterior half sprocket and located on an exterior side of the support frame. The drive sprocket transmits a rotational force to an endless track to rotate the endless track and propel the outdoor power equipment.

In regard to a hydraulic hose that extends from a center frame side in a lower travel body and is connected to a travel motor in each of right and left travel sections, it is possible to limit a movement range of a hydraulic hose with a simple configuration and thus to suppress damage to the hydraulic hose. A lower travel body that supports an upper unit includes: a center frame that supports the upper unit; a side frame that is provided on both of right and left sides of the center frame to support a travel motor and constitutes a crawler-type travel section; and plural hydraulic hoses, one end side of each of which is connected to a swivel joint provided to the center frame, and the other end side of each of which is connected to the travel motor. The center frame includes: a rear wall having a guide hole, through which the hydraulic hose passes; and a hose guide that is located below the guide hole, located above the hydraulic hose, and thereby restricts upward movement of the hydraulic hose.
