Abstract: A multi-row agricultural soil treatment implement includes a semi-trailed carriage and a rearward folding toolbar. The toolbar is suspended from the semi-trailed carriage through parallel links and includes a center section, flex hinges, main wings, main wing latches, and outer flip wings operatively connected to hydraulic cylinders to move them between transport and field position. The main wings fold rearward relative to the center section and are supported by a transport rack but they retain the ability to pivot up or down as needed for ground contour following capability or row end turning.

Abstract: A telescoping adjustable length trailer hitch with an hydraulic actuator for adjusting the length of the trailer hitch. The hitch being adjustable to provide for a longer hitch for road travel and for a shorter hitch for use in farm fields what used with a chemical applicator. The adjustable length hitch having an outside roller on the top of the tube which telescopes into the main tube and a roller on the bottom of the outside roller for rolling on the inside of the main tube to prevent binding as one tube moves inside the other. The telescoping tubes having a hinged safety link connecting the telescoping tubes so that they will not separate. The distal end of the trailer hitch having a bracket for adjusting the height of the trailer hitch relative the towing vehicle and a safety chain for ensuring trailer and towing vehicle will not become separated.

Abstract: A liquid chemical applicator tank made out of ultrahigh modular weight polyethylene which has a higher volume tank by use of a tank design with a narrower front end and wider rear end over the wheels of the trailer. The tank has wheel wells over the wheels, and a series of weldments on the frame engage indented ribs in the tank to help support the tank over the wheels. The tank has a short length and width while having a large volume such that the width is less than twelve feet, eliminating special road permits, while hauling up to 2400 gallons with a 62½ inches on-center lateral length between the inside wheel assemblies. The short length and low profile allows better tracking and greater visibility. Indented ribs in the tank engage weldments on the trailer frame to eliminate straps to hold the tank on the trailer.
