A power buggy is configured to be safe, stable, easy to control, and comfortable. Frequently-used controls, such as a dump control, a kill switch, and a directional control, are located at or very near handgrips of an operator's handle so as to permit the operator to control the vehicle without releasing either of the handgrips. The power buggy comprises a plurality of wheels and a movable chassis which is supported on the wheels and which has front and rear end portions. A dumpable article support is supported on the front end portion of the chassis. The power buggy also includes an axial piston hydrostatic pump assembly that has an axial piston pump which supplies power to the wheels and a second pump which charges a hydraulic system of the power buggy.

A spring suspension system according to claim 1 wherein a vehicle cab is pivotably connected to a vehicle by at least one pivot connection; and said cylinder having a housing pivotably connected to said cab-and a piston rod pivotably coupled to said vehicle. 8. A spring suspension according to claim 7 wherein said throttle valves are connected to one another in a direction toward said cylinder in fluid communication by a connecting line, said connecting line having a return valve therein opening in a direction of said first fluid chamber. 9. A spring suspension according to claim 8 wherein said dampening mechanism is in fluid communication with a fluid supply reservoir. 10. A spring suspension system according to claim 8 wherein said control mass comprises separate first and second partial control masses directly connected to said first and second throttle valves, respectively. 11. A spring suspension system according to claim 7 wherein said control mass comprises separate first and second partial control masses directly connected to said first and second throttle valves, respectively. 12. A spring suspension according to claim 1 wherein said throttle valves are connected to one another in a direction toward said cylinder in fluid communication by a connecting line, said connecting line having a return valve therein opening in a direction of said first fluid chamber. 13. A spring suspension according to claim 12 wherein said dampening mechanism is in fluid communication with a fluid supply reservoir. 14. A spring suspension according to claim 1 wherein said dampening mechanism is in fluid communication with a fluid supply reservoir. 15. A spring suspension system according to claim 1 wherein said control mass comprises separate first and second partial control masses directly connected to said first and second throttle valves, respectively. e for supporting a circuit board; providing an insulator for insulating said bolster plate from said circuit board; and securing said insulator to said bolster plate with one or more fasteners; wherein said securing said insulator to said bolster plate further comprises screwing at least one screw through said insulator and bolster plate, wherein each said screw comprises: a threaded portion; a head; and an unthreaded portion between said head and said threaded portion; wherein said insulating material and said bolster plate are held on said unthreaded portion of said screw between said threaded portion and said head. 22. The method of claim 21, wherein each said screw is held in said sub-assembly until unscrewed because said insulator will not slide over said threaded portion of said screw. 23. The method of claim 21, wherein each said screw rotates freely about said unthreaded portion in said insulator and bolster plate. 24. The method of claim 23, further comprising installing said sub-assembly by driving each said screw, which rotates freely about said unthreaded portion in said insulator and bolster plate, to screw said screw to a component on which said sub-assembly is to be installed. 25. A sub-assembly comprising: a bolster plate for supporting a circuit board; insulating means for insulating said bolster plate from said circuit board, wherein said insulating means are physically separate from said circuit board ; and fastening means, not including an adhesive, for securing said insulating means to said bolster plate. 26. The sub-assembly of claim 25, wherein said insulating means comprise: a sheet of insulating material sized and shaped to insulate said bolster plate; and at least one hole through said sheet of insulating material for accommodating said fastening means for securing said sheet of insulating material to said bolster plate. 27. The sub-assembly of claim 26, wherein said at least one hole further comprises: a round central portion; and a plurality of slots extending into said sheet of insulating material from said round central portion. 28. The sub-assembly of claim 26, wherein:
