Abstract: A snow bike includes a lightweight engine and transmission to power an endless drive belt (track) around a suspension under the rear of the frame. A unique aspect of the snow bike is that the front/rear weight distribution places less load on the ski and more load on the track, thereby providing lighter steering forces and increased track traction. The snow bike is steered by a fork mounted to a tubular/sheet frame that pivots around an axis and is connected to a ski. The drivetrain directly links the transmission to the track drive wheel, thereby powering the endless track. The centerline of the transmission drive shaft falls to the aft of the drive wheel of the track. This, combined with how the forward track suspension is attached, allows the mass of the track assembly to be more centralized, positioning the center of gravity of the bike nearer to the rider.

Abstract: A power-assisted wheelbarrow applies an assisting function using an electric motor. Handle shafts connecting to the rear end portions of two handles are covered with grips which are allowed to move axially relative to the handle shafts. More than one steel balls are fitted between the handle shafts and the grips. At the sides of the grips or the handles, pushing force detecting sensors are disposed for detecting the axial movements of the grips relative to the handle shafts in accordance with the pushing forces applied to the grips. The operation of the electric motor is controlled on the basis of the detected values of the two pushing force detecting sensors. As a result, the assisting force by the electric motor can be effectively applied to the wheel of a manual-push type single-wheeled carrier so that manual labor can be reduced while minimizing the consumption of a battery.

Abstract: A zero turning radius power lawn mower for operation by a standing occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero radius turning of the mower about a central turning point. The riding platform is positioned near this turning point or axis so that the standing occupant remains substantially unaffected by centrifugal force created during approximate zero radius turning of the mower thereby allowing the mower to take such turns at higher speeds. The low center of gravity created by the position of the riding platform for the standing operator also results in the mower having improved traction and being less likely to pop "wheelies" upon acceleration.

Abstract: To control the speed of a lawn mower, the speed of the lawn mower is changed in a forward direction along a longitudinal plane, resulting in a tendency to turn because of different speed characteristics of the right and left wheel drives. The speed is corrected by lateral movement of a control lever to increase the speed of one wheel motor and decrease the speed of the other wheel motor. When turning, if the lawn mower is not aligned along the longitudinal axis after the turn, the deviation is indicated in the position of the control lever to the right or left. This can be corrected by momentarily applying a motor speed change to one of said right and left hydraulic motors while observing the control lever until the control lever is centered in the longitudinal plane, whereby the speed of the lawn mower will be aligned along the longitudinal plane.
