A crop harvesting header includes a center portion mounted on two spring arms and two separate wings pivotally connected to the center portion. The wings are connected to the center portion by interconnecting linkages which transfer weight from the wings to the spring arms each including a balance beam arranged to balance the lifting force from the spring arm with the downward forces from the center portion and wing such that the downward force on a skid plate of each portion on the ground varies automatically as the total downward force is varied. The balance beams apply force to the linkages by a compression member to reduce forces. The movement caused by floating of the header and the change of angle of the header are compensated at the balance beam to ensure that the force to the wings is reduced as the requirement caused by changes in geometry reduces.

A transport system for a crop header includes a first and a second wheel arrangement on the header frame adjacent a respective ends for acting as a stabilizer when the header is in the operating position and movable to a transport position for transporting the header when removed from the vehicle in a transport direction generally longitudinal of the header frame and at a right angle to the working direction with each being mounted on the header frame for rotation of a rolling direction of the first wheel arrangement between the working position and the transport position, in which the rolling direction is along the transport direction. Each of the wheel arrangements includes two parallel wheels coupled together. The wheel arrangement at the rear end includes a second wheel which is mounted on a swing arm so as to be moved to a position adjacent the cutter bar so that the header is stably supported on the first wheel arrangement, the first wheel of the second wheel arrangement and the second wheel of the second wheel arrangement. The first and second wheels of the second wheel arrangement include coupling members for connection together to operate as a common wheel arrangement in the operating position. The swing arm includes a tower which attaches to the cutter bar and can fold down on to the swing arm in the field position.

A modular landscaper uses oversized wheels to generate torque for turning one or more of several interchangeable modular landscape maintenance attachments. The landscaper provides a handle configured in relationship to the landscaper frame to allow an adult to normally walk behind the landscaper while applying a forward force by pushing on the handle that results in the wheels of the landscaper rolling along a landscape maintenance surface and generating torque that is transferred through a drive train to the one or more attached landscaping maintenance attachments. A drive train uses the rotational energy of the wheels to increase the operator pushing force to operate the maintenance attachment. Interchangeable attachments facilitate using the landscaper for a wide variety of landscaping maintenance tasks.

An implement has a tongue used to tow the implement that can be raised or lowered with respect to the rest of the implement. The tongue is raised or lowered by a hydraulic cylinder.
