Abstract: An onboard lift for a pontoon boat has four legs pivotally attached underneath a platform and extending between the outer pontoons. Each leg terminates in a slide foot. The pivot pin for each leg is canted, such as at 13° relative to horizontal. In a stowed position, the legs and slide feet extend forward in the direction of travel and tight to the platform. When used to lift the boat, actuation of the legs pushes the slide feet outward due to the cant of the pivot axis, such that the slide feet are positioned underneath the outer pontoons when the boat is fully raised. The control allows separate powering of the front legs from the rear legs, and further has a display so the user can see the amount of extension of each set of legs.

Abstract: An onboard lift for lifting a boat such as a pontoon boat includes legs that have one end pivotally attached to a bottom substantially horizontal surface of a boat deck. The legs are typically continuous substantially imperforate tubes throughout essentially the entire length. The lower ends of the legs carry support feet or pads. One end of an actuator attaches to an outer side of one of the tubular legs and another end of the actuator is attached to a bottom substantially horizontal bottom surface of the boat deck. The actuators are manipulated to pivot each of the legs between a retracted or stowed position where the legs are substantially parallel to the bottom substantially horizontal surface of the boat deck and a working or lifting position where a pad or foot engages the bottom of the body of water and as the legs are further pivoted downwardly, the boat is lifted upward and out of the water.

Abstract: An onboard lift leg construction for a pontoon boat has a plurality of movable support legs including rear telescoping tube support legs that are fixed to a frame of a pontoon boat. The telescoping tube support legs each include an outer tube fixed to the frame, and an inner tube slidably mounted within the outer tube. A linear hydraulic actuator is secured to a head member that is supported on the outer tube. The actuator has an extendable and retractable rod that is attached or secured to the lower end of the inner tube such that when the actuator is extended, the inner tube is also extended to effectively lift the pontoon boat to which the outer tube is attached. The forward portions of the pontoon boat frame can be provided with pivoting lift legs for lifting the pontoon boat.

Abstract: A row crop cultivator is provided with a seed dispensing manifold attached to and spanning the lay shares forming a part of its middleworker assembly. The seed distribution manifold is designed to randomly distribute seeds fed into it from a towed planter assembly that includes a seed hopper, metering means for feeding out seeds from the hopper in accordance with the ground speed of the apparatus and a blower for forcing the seeds through suitable tubes to the seed distribution manifold.

Abstract: A toolbar having a fixed center section and folding wing sections is mounted to and drawn by a tractor. The wings are each connected to the center section by a bi-fold hinge assembly which allows the wing either to fold upwardly for transport or to a forward position. The forward movement is automatically effected in response to the turning of the tractor to allow the toolbar to clear a drawbar-mounted drawn implement positioned aft of the toolbar. A lock pin is placed by the operator in one of two positions to determine the desired mode of operation.

Abstract: A telescoping row marker for use with a conventional agricultural tillage apparatus such as a tractor carried, or pulled, planter, cultivator or the like; for the alignment of soil working implements with crop rows is disclosed. Positioned within a hollow mounting bar open at both ends are first and second telescoping marker arms having marking means attached to the distal ends and engageable track means located along the length thereof. Positioned adjacent respective ends of the mounting bar are first and second drive means engaging the track means of an adjacently positioned marker arm for displacing the marker arms along the hollow mounting bar whereby the marker arms may be fully extended in the working position or may be fully retracted for transporting or maneuvering the tillage apparatus.
