  • Patent number: 11293333
    Abstract: An outdoor unit has a frame that carries a ground grooming or working implement, a traction drive, and a cooling fan, all of which comprises loads on a prime mover. A power management controller automatically reduces an operational speed of the traction drive when prime mover droop is present. The cooling fan cools two cooling fluids. The controller stores data representing variable fan speeds for cooling each cooling fluid in both normal and above normal temperature ranges and for use when prime mover droop is present. The controller uses the highest fan speed required for cooling the cooling fluids in the normal range unless the droop fan speed is lower in which case the lower droop fan speed is used but only to the extent that the lower droop fan speed is not lower than the highest fan speed required for cooling the cooling fluids in the above normal temperature range.

  • Patent number: 8880300
    Abstract: An outdoor power equipment unit comprises a self-propelled mower having a hydraulic traction drive system. When engine load exceeds a predetermined percentage of full load, a controller automatically reduces the stroke of a variable displacement pump in the traction drive system to reduce the ground speed of the mower without the operator having to change the position of the traction pedal. This reduces engine load to enhance continued good cutting performance. At any time, the controller can take the same actions to reduce ground speed if an excessively high temperature in a fluid used in a cooling system on the mower is detected, or if excessive loads on the mower decks of the mower are detected, or both.

  • Patent number: 8561382
    Abstract: A stand-on riding mower has a support platform at the rear thereof for supporting an operator who stands during operation of the mower. The support platform is pivotally connected to the traction frame of the mower by a suspension that includes pivotal support plates at each side of the platform. At least one spring is arranged to push against the pivotal support plates in a direction causing the platform to rise such that the weight of the operator atop the platform causes the platform to lower until increasing biasing force in the spring balances the operator's weight. The spring ensures that impact shocks and the like on the traction frame of the mower are cushioned before reaching the operator's platform. In addition, the operator's platform is pivotal relative to the support plates to allow the operator's platform to be disposed in both a vertical stowed position and a horizontal deployed position.

  • Publication number: 20120285753
    Abstract: An all-wheel steering system and vehicle, e.g., riding lawn mower, incorporating the same. The system may include a linkage system that operatively connects the vehicle wheels for simultaneous turning. The system, in one embodiment, includes a power steering unit having fixed or variable output for a given steering input. The system may further include a mechanism for reducing speed based upon mower steering angle.
