Abstract: An electric cart for facilitating the harvesting of berries and other crops comprising a steering side wheel assembly with a front steering wheel and a rear drive wheel connected by a first connecting member and a caster side wheel assembly comprising a front caster wheel and a rear drive wheel connected by a second connecting member. Both drive wheels are connected to battery-powered motors. A main cross-bar connects the castor side wheel assembly to the steering side wheel assembly and maintains an adjustable distance between the first and second connecting members. The invention preferably includes a plurality of solar panels that charge the batteries that supply power to the first and second battery-powered motors.

Abstract: An agricultural implement includes a traction structure and a tool beam rearward of the traction structure. First and second wheeled support structures support the tool beam at opposite respective ends of the tool beam. First and second linkages each have a forward portion connected to the traction structure and rearward portions connected to the first and second support structures respectively. An actuator is effective between the traction structure and the first linkage for selectively adjusting an angular position of the first linkage relative to the longitudinal axis of the traction structure. The tool beam provides a force transmitting connection between the rearward portions of the first and second linkages whereby angular movement of the first linkage relative to the traction structure is accompanied by angular movement of the second linkage relative to the traction structure.
