Abstract: A power machine with an engine, a drive pump driven by the engine, and a drive motor operably coupled to the drive pump to receive a drive signal and provide a motor output to effect travel of the power machine is disclosed. A brake system on the power machine includes a brake for reducing or stopping movement of the power machine. A controller receives indications of a braking condition and whether the drive pump is outputting the drive signal. The controller determines in response to receipt of the indication of the braking condition whether the drive pump is outputting the drive signal to the drive motor shuts down the engine if the drive pump is providing the drive signal to the drive motor upon receipt of the braking condition.

Abstract: A hydraulic brake mechanism for use in hydraulic systems to provide braking of a hydraulic motor is disclosed. The brake mechanism provides proper braking under a range of operating conditions, including (1) the start of flow from the pump to the brake and motor and braking is not desired; (2) operating conditions in which constant flow is provided from the pump to the brake and motor and braking is not desired; (3) operating conditions in which abrupt decreases of flow from the pump to the brake and the motor occur, for example where flow is reduced due to being drawn by another work element or hydraulic load, but under which a reduced supply flow is still present and braking is not desired; and (4) operating conditions in which the hydraulic flow from the pump to the brake mechanism and the motor is shut off completely and braking is desired.

Abstract: A disclosed power machine has a power source with a rotational output that drives a first axle assembly with first and second wheels with one of the first and second wheels being a sensed wheel. Wheel speed and rotational speed sensors monitor the rotation speed of the first sensed wheel and the rotational output, respectively. A controller communicates with the wheel speed sensor, the rotational output speed sensor, and a braking system that is operable to brake the first and second wheels. A controller calculates, as a function of the sensed wheel and rotational output speeds, a traction score indicative of whether one of the first wheel and second wheel is slipping and signals to the braking system to brake the first wheel when the traction score indicates that the first wheel is slipping and brake the second wheel when the traction score indicates that the second wheel is slipping.

Abstract: A ride-on operator platform or sulky is used in connection with a small self-propelled loader to provide a support for an operator. The operator platform is pivotally mounted to the loader about a generally horizontal axis, and has a rear support engaging the surface over which the loader is operating to maintain the operator platform at a desired position relative to the surface. The upward pivoting of rear portions of the operator platform is limited by stop members, and substantial downward pivoting is permitted.
