  • Patent number: 12157443
    Abstract: An outdoor grounds maintenance vehicle is self-propelled by a hydrostatic traction drive system that provides dynamic braking to the vehicle without the need for separate service brakes acting on the wheels of the vehicle. An engine kill device can be manually actuated by the operator to access the dynamic braking of the traction drive system by reducing the speed of the prime mover that powers the pump of the traction drive system. This provides an auxiliary braking system that can be used in an emergency or on demand by the operator in the event the accelerator pedal does not properly control the pump swashplates. The operator can control the rate at which the auxiliary brake system reduces the speed of the prime mover to zero.

  • Publication number: 20230329146
    Abstract: A mower comprises a frame carrying a front mounted rotary cutting deck. A deck lift moves the cutting deck between mowing and transport positions. The cutting deck can be selectively pivoted on the deck lift into a substantially tipped up service position to expose the underside of the cutting deck for service. The cutting deck has a self-engaging latch to hold it in its service position. A self-engaging catch provides a temporary hold position for the cutting deck that is short of the transport position as the cutting deck is being returned from the service position to prevent inadvertent contact between the cutting deck and the user. For ease of use, both the latch and the catch are releasable by a user from one side of the cutting deck which side also includes a rear foot pad and a front hand grip on the cutting deck.
