Abstract: An apparatus for use in a power delivery system, the apparatus comprising: a DC circuit breaker having first and second terminals and configured to automatically switch from a closed state to an open state during an overcurrent condition; a disconnector switch in series with the DC circuit breaker, the disconnector switch having a first terminal for connecting to a first polarity terminal of a DC power supply, a second terminal for connecting to a second polarity terminal of the DC power supply and a common terminal connected to the first terminal of the DC circuit breaker, the disconnector switch having at least a first position in which the first terminal is connected to the common terminal and a second position in which the second terminal is connected to the common terminal; and an interlock mechanism coupled to the DC circuit breaker and the disconnector switch, the interlock mechanism configured to disable the DC circuit breaker from automatically switching from the closed state to the open state during

Abstract: A method of controlling a grading attachment on a skid steer vehicle that includes the steps of lowering a main arm of a skid steer vehicle with either an electric non-hydraulic cylinder or a drive motor to the main arm’s lowest allowed position along an arm translation path on the skid steer vehicle and adjusting, while the main arm is the in the lowest allowed position, either or both a pitch axis movement and/or a yaw axis movement of a grading attachment coupled to the main arm autonomously using an automatic grade control system implementing at least one of a laser, a GPS, an LPS, and an ultrasonic sensor and with at least one a plurality of electric non-hydraulic cylinders and drive motors, wherein the automatic grade control system is communicatively coupled to the at least one a plurality of electric non-hydraulic cylinders and drive motors.

Abstract: A method of stabilizing a small to mid-sized skid steer vehicles used to grade earth using a dozer blade in conjunction with GPS automatic grade control equipment. The main arm of the skid steer is retained at a specific height and the hydraulic controlling the main arm is limited. The height of the dozer blade is raised and lowered by affecting the pitch axis of movement of the blade and not by raising and lowering the main arm. The device is most suited to skid steer vehicles capable of using a variety of interchangeable front end accessories in addition to a dozer blade.

Abstract: A skid steer control box used with a dozer blade attachment and laser control system that integrates the laser controller and native skid steer controller as they affect a selected solenoid related to a hydraulic valve.

Abstract: A hydraulic control system for an earth-moving vehicle with an automatic grade control system that hydraulically powers the height of the blade through the hydraulic accessory port. When using a laser based system the main arms are controlled through the accessory port and a pitch movement of the blade is limited. When using a GPS based system the accessory hydraulic is disconnected from the main arm and reconnected to the pitch hydraulic to affect the height of the blade.

Abstract: An attachment for the rear of a skid steer type vehicle to connect any of a variety of commercially available attachments to the rear of that vehicle. A pair of hydraulic actuators articulate the arm assembly relative to the plate assemblies affixed to the vehicle to raise and lower the attachment.
