Abstract: A zero ground disturbance dike apparatus and method for the secondary containment of harmful chemicals that are stored in primary storage vessels, wherein the dike apparatus does not require the drilling of postholes or the setting of support posts in concrete. Sections of dike walls are attached to bracing assemblies, each bracing assembly being comprised of a brace and a base plate. Braces are configured to support the assembled wall sections and to provide resistance against the outwardly force exerted by material that is released from the primary storage vessel. Base plates attached to the braces assist in resisting bending moments that may be created about the base of the dike apparatus. The brace assembly also preferably includes at least one base support channel for additional base plate stiffness and support cables to further resist the outwardly forces exerted against the dike apparatus by said released materials.

Abstract: A hydrostatic drive for a utility vehicle includes a prime mover (engine) which drives a variable rate hydrostatic pump. In a two-wheel drive system, the hydraulic fluid flow from the pump is split evenly and directed to the rear wheel motors. This flow turns the rear wheel motors and then exits the wheel motors where it is directed back to the pump. In a four-wheel drive system the flow from the pump is split evenly between the front wheel motors. The flow exiting the front motors is directed to the rear wheel motors on the opposite sides of the vehicles. This flow turns the rear motors and then is directed back to the pump. Direction and speed of the vehicle is regulated by an operator-controlled actuator which controls the direction and displacement of the hydrostatic pump. A neutral valve is interconnected between the pump and the motors.
