  • Patent number: 4586677
    Abstract: A take-up system for drip irrigation lines consisting of a mobile frame supported on wheels or skids. A predetermined number of take-up bays are provided along the frame. Each bay includes a cable spindle which is positively driven across a clutch by a hydraulic or pneumatic motor. A disk brake is hydraulically actuated to allow the operator to control the speed of the reel. A bearing support assembly is detachably secured to the reels. Each reel bay further includes a leveler which consists of a mechanically oscillatable carriage having a guide at the bottom through which one tubing line passes. The leveler applies the line on the reel evenly as the reel rotates. Cable reels may be removed and replaced with empty reels as required. The device is also operable to control pay-out of lines when the lines are being placed in the field at the beginning of the growing season.

  • Patent number: 4359106
    Abstract: The rowbucker apparatus for scraping and extending berm areas adjacent an irrigation ditch. The rowbucker comprises a frame that is towable by a tractor and supports a rotor for rotation. A tramper or trip mechanism is provided to engage the moldboard surfaces of the rotor to arrest rotation. The tramper mechanism includes at least one roller connected to a rockshaft through an arm. The rockshaft may be rotated by a hydraulic actuator to bring the roller in engagement with the moldboard surfaces in a scraping position or to disengage to deposit the scraped up material on the ground establishing a berm when the rotor is released.
