1. A vacuum system, comprising:
a tank extending from a first end to a second end, comprising:
a door disposed at the second end; and
a mount disposed at the first end;
a frame supported by a plurality of ground-supporting members, wherein the tank is supported on the frame; and
a cylinder assembly comprising:
a first cylinder comprising a first barrel and a first rod, wherein the first rod is attached to the frame at a first connection point; and
a second cylinder comprising a second barrel and a second rod, wherein the second rod is attached to the mount at a second connection point;
wherein the first barrel and second barrel are joined together;
wherein the tank is pivotally attached to the frame at its second end at a third connection point; and
wherein a first horizontal distance is defined by a horizontal distance between the first connection point and third connection point and a second horizontal distance is defined by a horizontal distance between the second connection point and the third connection point, wherein:
the first horizontal distance is greater than the second horizontal distance when the first rod and the second rod are fully extended; and
the first horizontal distance is less than the second horizontal distance when the first rod and the second rod are fully retracted.
