A machine includes a front section having front wheels, a rear section having rear wheels, and a pivot that couples the front section to the rear section as well as a hydraulic steering circuit that moves the front section relative to the rear section about the pivot. The machine also includes a stabilizer and further includes a directional control valve that selectively depressurizes the hydraulic steering circuit according to a state of the stabilizer.

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 robotic vehicle may include a first chassis platform including a first wheel assembly, a second chassis platform including a second wheel assembly where the first and second chassis platforms are spaced apart from each other, and a combination linkage operably coupling the first and second chassis platforms. The combination linkage may be operably coupled to the first chassis platform via a first link and is operably coupled to the second chassis platform via a second link. The combination linkage employs at least two different coupling features to operably couple the first and second chassis platforms. The at least two different coupling features include at least any two among a fixed attachment, an attachment that enables rotation about a turning axis, and an attachment that enables pivoting about a pivot axis that is substantially perpendicular to the turning axis.

A vehicle or machine suitable for operation on uneven or inclined surfaces, such as a forest work unit, comprises at least three frame parts and two rotational planes. Each frame part has rotational planes, in each particular case, on an interface between two successive frame parts of the vehicle or machine. The rotational planes are, in each particular case, planes perpendicular to the longitudinal axis of the vehicle or machine in the neutral position. The frame parts are thus arranged to be independently rotatable in relation to the rotational plane.
