An articulating cart system which utilizes an articulating frame to effectively maneuver within tight spaces and a low-elevation platform to ease mounting and dismounting the cart. The articulating cart system generally includes a front frame and a rear frame. A platform is connected to the front frame so that the platform pivots or articulates along with the front frame with respect to the rear frame. A joystick controller may be provided which allows one-handed operation. One or more actuators may be connected between the rear frame and the front frame for pivoting the front frame with respect to the rear frame. A motor is provided to power the actuators and frame wheels. The platform is close to the ground to ease access for the operator. Utilizing the articulating frame, the present invention may traverse much tighter spaces and turns than is possible with previous cart systems.

A vehicle has first and second parts with at least one road wheel. The first part pivotally connects to a connecting member at two spaced apart points to pivot about a first axis relative and the second part pivotally connects to the connecting member at two spaced apart points 18 to pivot about a second axis, which is perpendicular to the second axis, intersecting at a pivot point. A first drive shaft rotatably mounts to the first part and extends in a direction perpendicular to a longitudinal axis of the first part, a second drive shaft rotatably mounts to the second part and extends in a direction perpendicular to a longitudinal axis of the second part. The first and second drive shafts connect by a universal joint so that the two shafts to pivot relative to each other about the pivot point.

According to certain embodiments, a convertible recreational vehicle comprises one or more front ground engaging members; one or more rear ground engaging members; a frame supported by the one or more front ground engaging members and the one or more rear ground engaging members. In addition, the convertible recreational vehicle comprises a steering assembly configured to steer the one or more front ground engaging members. In addition, the convertible recreational vehicle includes a seat assembly supported by the frame and configured to support at least one rider and a motor configured to drive at least one of: (i) the one or more front ground engaging members and (ii) the one or more rear ground engaging members. Further, the convertible recreational vehicle includes a floor panel including a surface that extends across a width of the floor panel.

Sulky apparatus for use behind a self-propelled operator controlled machine such as lawn mowers that includes a sulky riding platform, a sulky boom having an inner end and an outer end for connecting the sulky riding platform to the self-propelled machine that is to tow the sulky riding platform, a pivotal connecting system for pivotally connecting the sulky riding platform to the outer end of the sulky boom and an adjusting system for adjusting the pivotal connecting system. The adjusting system for adjusting the pivotal connecting system is particularly useful in properly connecting the sulky apparatus to self-propelled machines that have different height frames. In another embodiment of the sulky apparatus invention for use behind a self-propelled machine that has operator control handles that includes a sulky riding platform, a sulky boom having an inner end and an outer end for connecting the sulky riding platform to the self-propelled machine that is to tow the sulky riding platform the invention includes a storage system for storing the sulky riding platform below the operator control handles of the self-propelled operator controlled machine. The storage system also includes an important brake system for preventing swinging or similar movement of the stored sulky riding platform.

A ground maintenance vehicle that includes: front steering wheels; rear drive wheels; a frame with a first and second pivot point; a single lever steering assembly with a single lever steering control, where the single lever steering assembly is coupled to the first pivot point; multi-axis articulating joint coupled to the second pivot point; a front caster steering assembly coupled to the multi-axis articulating joint; and where the front caster steering assembly and the multi-axis articulating joint simultaneously provide articulating and caster steering proportional to lateral movement from the single lever steering control.
