Abstract: A marine outdrive has a hydraulic vane motor with a spool shaped rotor eccentrically mounted in a fusiform shaped housing. The resulting increased vane area results in greater torque and speed.

Abstract: A lawn mower blade, particularly suited for a rotary lawn mower is provided with at least two end tines at opposite ends. Each tine has a forward bevelled cutting surface. The rear most and lowest most end tines are in a common (lowest) plane while all other tines are respectively forward thereof and in planes above the common plane. There are preferably three tines at each end which, on rotation, trace out a grass cutting annulus. The tines rotate in this annulus, chopping up the grass cuttings into small pieces virtually consuming them. The cut grass clippings thus not accumulated to the underside of the lawn mower deck and then fall as clumps to leave an unsightly mess on the ground.
