Abstract: A mulling system for a plurality of fenestration units includes a first joining plate configured to attach to a first outer edge of a first fenestration unit. The first joining plate includes a first outer face. The mulling system also includes a second joining plate configured to attach to a second outer edge of a second fenestration unit. The second joining plate includes a second outer face. The second joining plate is configured to engage the first joining plate to join together the first fenestration unit and the second fenestration unit with the first outer face facing the second outer face. The mulling system additionally includes a deflectable seal member attached to the first joining plate and having a sealing surface that faces away from the first outer face. The sealing surface is configured to deflect and seal against the second outer face of the second joining plate.

Abstract: A lawn mower may include a blade housing configured to house at least a first blade and a second blade, a shaft disposed to rotate within the blade housing, a powerhead configured to selectively turn the shaft responsive to application of power from a power source, and a blade coupler configured to selectively couple the first blade and/or the second blade to the shaft to produce different cutting performance conditions based on which of the first blade and/or the second blade is operably coupled to the shaft.

Abstract: An outdoor power machine proximity-based control system includes: a controller operably connected to an outdoor power machine, the controller being configured to control a pre-determined function of the outdoor power machine in response to a triggering event, the controller including a communications device configured to receive a signal indicative of a location of an object relative to the outdoor power machine, wherein in response to the received signal, the controller compares the location of the object to a pre-determined threshold and in response to the comparison causes an action to prevent interaction between the outdoor power machine and the object.

Abstract: An outdoor power machine apparatus includes a prime mover, such as a combustion engine or an electric motor. The outdoor power machine is operable to carry out machine function, e.g. a material handling function. An electronic controller is connected to a machine function and identifies a specific user and controls the machine function based on the identity of the user. The controller may be configured to permit or deny operation of the machine function based on the user's identity. The controller may be configured to operate the machine function in a desired manner based on the user's identity.
