A vertical motion battery latching mechanism for a power equipment having a removable battery can include a central lever, a latch button and a vertically pushed button. The central lever can be configured to rotate about an axis. The latch button can be vertically movable by rotation of the central lever and configured to selectively secure and release the battery with respect to the power equipment. The latch button can be biased toward securing the battery onto the power equipment. The vertically pushed button can rotate about a second axis different from the first axis and be configured to contact the central lever to rotate the central lever about the first axis and release the battery from the power equipment by moving the latch button vertically.

Collection vessel fill-indicator assemblies and mowers with collection vessel fill-indicator assemblies are provided. A collection vessel fill-indicator assembly includes a capacitance element configured to be disposed adjacent to a collection vessel of a mower to detect a fill state of the collection vessel; and an interference guard disposed around a portion of the capacitance element to shield the capacitance element from interference.
