Abstract: An automatic reversible arc assembly for a sprinkler includes a pair of primary stop members circumferentially spaced from each other by a first amount, and a pair of secondary stop members circumferentially spaced from each other by a second amount, different from the first amount. The primary stop members and the secondary stop members are coupled together and define a pivot assembly pivotable between a first position and a second position. A timer module cooperable with the pivot assembly is configured to hold the pivot assembly in the first position for a selectable period of time, after which the timer module enables the pivot assembly to pivot to the second position. The primary stop members are active in the first position, and the secondary stop members are active in the second position.

Abstract: A quick connect joint includes a base with first and second lock receivers on opposite sides of the base, and a connection plate including first and second engagement members engageable with the first and second lock receivers, respectively. The first engagement member is displaceable between a release position and lock position, and the first engagement member is rotatable between an insert position and a connect position. The quick connect joint creates a safe and reliable connection.

Abstract: A scrubber filter assembly including: a shaft mounted in an interior passage of a housing and configured to reciprocally move within the housing; a water outlet coupling on a side of the shaft which extends through a slot in the housing wherein the outlet coupling moves reciprocally within the slot as the shaft moves reciprocally, an inlet at a distal end of the shaft and the inlet extends into a water passage within the collar, wherein the inlet includes an outer surface having a filter configured to allow water to enter the inlet and prevent debris entering the water passage; and an edge extending around the perimeter of the outer surface of the inlet, wherein the edge is fixed to the collar, and the edge is configured to scrape debris from the filter as the inlet moves reciprocally with the shaft.

Abstract: A linear irrigation system includes a linear irrigator movable in a first direction along a path of travel and including plural towers supporting a truss assembly extending laterally in a direction substantially perpendicular to the path of travel. The truss assembly carries a plurality of sprinklers connected to a water supply pipe. A plurality of hydrants are spaced along the water supply pipe, each hydrant having a valve, and a pair of laterally adjacent trolleys are mounted on an elongated frame for movement in two opposite directions, each trolley having a docking station and hydrant valve actuator, the docking stations resiliently suspended from said trolleys for movement in at least three mutually perpendicular directions and adapted to engage and disengage, successively, the plurality of hydrants on the supply pipe extending below and between the pair of trolleys. The trolleys and docking stations may be carried on a mobile cart or incorporated into the linear irrigator.
