Abstract: Hitch for interconnecting a tractor to a towed implement such as a sprayer, operated by a power takeoff (PTO) of the tractor. The hitch has a turning axis located close to the front of the implement, and a universal joint in the PTO shall be in vertical alignment with the turning axis. The towed implement thus more nearly tracks the tractor in turn, and the universal joint undergoes less vibration and thrust loading during turns.

Abstract: A sprayer reduces undissolved particulates in a liquid spray solution by pumping jets of the liquid toward an impact surface within the tank of the sprayer. The liquid jets and the impact plate are above the liquid in the tank, and the liquid drains into the tank after striking the plate. A screen keeps remaining undissolved particulates from the sprayer nozzles but not from the liquid flowing to the impact plate.

Abstract: Disclosed is a tool for holding a lawnmower blade for installation and removal thereof. The tool comprises an elongate lever having a handle at one end, a blade engaging section about the other end, and a channel therebetween for accommodating the housing of a lawnmower. The blade engaging section comprises a pair of spaced-apart adjustably mounted stop pins for preventing rotational movement of a lawnmower blade placed therebetween. The stop pins have inwardly-facing retaining heads for preventing the lawnmower blade from slipping off said stop pins.
