  • Patent number: 9370175
    Abstract: A vehicle mounted sprayer has a plurality of spray booms equipped with downwardly facing spray nozzles. A control console includes a rounded palm rest with the most often used operational spray controls placed directly ahead of the palm rest for easy actuation by the operator as the operator rests the palm of one hand on the palm rest. A pivotal hose reel for manual spraying has pivotal motion about a vertical axis into one of a plurality of adjusted positions relative to the sprayer to ease unwinding and rewinding of the hose from the hose reel. A hill assist system holds the sprayer on a hill for a predetermined time to give the operator enough time to place the sprayer into forward motion up the hill from a standing stop. The spray through the booms can be selectively added to flow in a tank agitation system to boost agitation effectiveness.

  • Publication number: 20150361932
    Abstract: An air cleaner system that potentially reduces debris entering a prime mover (e.g., engine) during removal/replacement of an air cleaner. In one embodiment, the engine includes a shroud defining an air cleaner compartment. The engine further includes a tubular air feed port defining a combustion air intake. The air feed port terminates at an end face located at or within the air cleaner compartment, and a lower portion of the end face is notched relative to other portions of the end face. In other embodiments, an engine oil drain system is provided that selectively positions a distal end of an oil drain tube at a drain position located away from the engine. The oil drain tube may also be repositioned to a stored position, wherein the distal end of the drain tube attaches to a nipple connected to either an engine housing or surrounding structure.

  • Patent number: 7870640
    Abstract: A convertible blower/vacuum for selectively blowing or vacuuming debris. The blower/vacuum may include a housing to which a blower/vacuum tube is coupled. The tube may be movable, relative to the housing, to allow a primary passageway of the tube to selectively communicate with either an air inlet of the housing or an air outlet. The blower/vacuum may further include a vacuum receptacle having an opening that selectively communicates with the air outlet when the passageway of the tube communicates with the air inlet.
