1. A stand-on compact utility loader (CUL) configured for connection to and operation of a variety attachments, the CUL comprising:
a frame;
a pair of loader arms coupled to opposite sides of the frame and shiftable relative to the frame between a lowered position and a raised position;
a pair of pivot pins each associated with one of the loader arms, wherein the pivot pins are configured to connect the attachments to the front of the loader arms, wherein the pivot pins follow a curved travel path from a base position to a maximum height position when the loader arms are shifted from the lowered position to the raised position, wherein the curved travel path is approximated by a function f(x)=4.641e0.34x, wherein “x” represents a horizontal distance, in inches, from the base position and f(x) represents a vertical distance, in inches, from the ground, wherein the curved travel path deviates from the function by not more than 1.5 inches in the horizontal direction between the base position and the maximum height position;
a pair of tracks positioned on opposite sides of the frame;
a front idler wheel and a rear idler wheel associated with each of the tracks, wherein a center of gravity of the CUL is positioned rearward of a midpoint situated evenly between the front and rear idler wheels;
a drive sprocket associated with each of the tracks and positioned vertically above and horizontally between the front and rear idler wheels of each track; and
a hydraulic motor associated with each of the tracks and configured to power the drive sprocket of each track.
