1. An apparatus comprising: a gas powered walk behind mower comprising:a deck;a gas powered engine supported by the deck; anda rotating cutting blade driven by the gas powered engine, wherein the deck is configured to be stored in a generally vertical orientation;a handle extending from the deck and pivotable relative to the deck about an axis between an operating position and a folded position;a brake actuatable between a braking position in which driven rotation of the blade is stopped and a released position in which the blade is drivable by the engine, the brake being biased towards the braking position;a manual actuator carried by the handle and movable against a bias to an actuated position;a release line extending from the manual actuator to the brake to move the brake towards the released position in response to the manual actuator being moved to the actuated position when the handle is in the operating position; anda release line pivot point, wherein the axis is between the release line pivot point and the manual actuator and wherein a sufficient portion of the release line between the release line pivot point and the manual actuator is sufficiently flexible such that pivoting of the handle towards the gas powered engine towards the folded position creates sufficient slack in the release line such that the brake remains biased in the braking position even while the manual actuator is in the actuated position. 2. The apparatus of claim 1, wherein movement of the manual actuator moves an end of the release line by a distance wherein a spacing between the release line pivot point and the axis is greater than or equal to the distance. 3. The apparatus of claim 1, wherein, prior to an end of the handle being pivoted forward of the axis, the brake remains biased in the braking position with the manual actuator in the actuated position. 4. The apparatus of claim 1, wherein the deck carries a plurality of wheels and wherein at least one of the wheels is elevated off ground when the deck is in the vertical orientation. 5. The apparatus of claim 1, wherein the handle extends substantially parallel to the deck when the deck is in the vertical orientation. 6. The apparatus of claim 1 further comprising: an oil sump;a first oil drain port extending in a first direction through a first wall of the sump, wherein the first wall forms a bottom of the sump when the deck is in the vertical orientation. 7. The apparatus of claim 6, wherein the oil drain port is configured to be releasably connected to an oil cartridge with the oil cartridge being upright when the deck is in the vertical orientation. 8. The apparatus of claim 7, wherein the oil drain port is internally threaded for receiving an externally threaded spout of the oil cartridge. 9. The apparatus of claim 7 further comprising a drain port closing mechanism actuatable between a port closing position and a port opening position, wherein the mechanism is biased to the port closing position when the deck is in the vertical orientation and wherein the mechanism moves against the bias to the port opening position upon receipt of a spout of the cartridge by the oil drain port. 10. The apparatus of claim 9, wherein the port closing mechanism is biased to the port closing position by gravity when the deck is in the vertical orientation. 11. The apparatus of claim 9, wherein the port closing mechanism comprises a flapper configured to pivot between the port closing position and the port opening position. 12. The apparatus of claim 11, wherein the flapper comprises a membrane perforation device configured to puncture sealing membrane across a port of the oil cartridge during insertion of the cartridge. 13. The apparatus of claim 7 further comprising the oil cartridge, wherein the oil cartridge includes an outermost wall having outer surfaces forming an exterior of the oil cartridge and opposite inner surfaces, a continuous empty interior extending from and between the inner surfaces of the outermost wall and a spout connected to the continuous empty interior and extending adjacent a corner of the cartridge. 14. The apparatus of claim 6 further comprising a second oil drain port through a second wall of the sump, wherein the second wall forms the bottom of the sump when the deck is in the horizontal operating orientation. 15. The apparatus of claim 6 further comprising: a flexible hose having a first end and a second end, the first end being connected to the oil drain port while the second end is releasably mounted to the mower. 16. The apparatus of claim 15 further comprising: a hose cap coupler connected to the second end of the flexible hose;a cap removably coupled to the cap coupler; anda clip supported by at least one of the cap and the coupler, the clip being configured to resiliently flex to resiliently capture and retain an attachment point of the mower between the clip and the hose cap coupler. 17. The apparatus of claim 6, wherein the oil drain port has a single continuous opening with a diameter sufficiently large to inhibit burping during exchange of air and oil through the oil drain port. 18. The apparatus of claim 6, or the oil drain port has a single continuous opening with an area of at least 0.3852 inches. 19. The apparatus of claim 1, wherein the release line extends uncovered adjacent a first side of the release line pivot point towards the axis and wherein the apparatus further comprises a sheath about the release line on a second side of the release line pivot point. 20. The apparatus of claim 1 comprising a sheath about the release line between the release line pivot point and the brake, the sheath terminating at the release line pivot point. 21. The apparatus of claim 1, wherein the brake remains biased in the braking position while the manual actuator is in the actuated position during pivoting of the handle about the axis. 22. The apparatus of claim 1, wherein the brake actuates between the braking position and the released position all while the manual actuator is actuated in response to pivoting of the handle about the axis. 23. The apparatus of claim 1, wherein the release line is taut between the release line pivot point and the manual actuator. 24. The apparatus of claim 1, wherein the release line linearly extends from the release line pivot point to the manual actuator.
