1. A lift device, comprising:
a base;
a platform; and
a scissor assembly coupling the base to the platform, comprising:
a first scissor layer including a first inner arm pivotally coupled to a first outer arm, wherein the first inner arm is configured to rotate relative to the first outer arm about a first middle axis,
wherein the first scissor layer has a first end axis center point positioned at an intersection of (a) a first straight line that extends from an upper end of the first inner arm to a lower end of the first inner arm and (b) a second straight line that extends from an upper end of the first outer arm to a lower end of the first outer arm;
a second scissor layer coupled to the first scissor layer, the second scissor layer including a second inner arm pivotally coupled to a second outer arm;
a third scissor layer coupled to the second scissor layer, the third scissor layer including a third inner arm pivotally coupled to a third outer arm;
an actuator configured to move the platform between a fully raised position and a fully lowered position relative to the base; and
a kicker assembly coupling the actuator to the second scissor layer and the third scissor layer, the kicker assembly comprising:
a kicker having opposing first and second kicker ends, the kicker pivotally coupled to the second scissor layer proximate the first kicker end and releasably coupled to the third scissor layer proximate the second kicker end, wherein the kicker is operably coupled to the actuator between the first and second kicker ends such that the actuator is configured to rotate the kicker relative to the second scissor layer; and
a guide coupled to the kicker and configured to limit the rotation of the kicker,
wherein the first middle axis of the first scissor layer is offset vertically from the first end axis center point.
