Hello Richard,

Hopefully with the help of the illustration I can convey to you the measurements you seek. The units of measure I use are millimeters.

Wheel diameter - 540
Distance from end of boom to center of the axle mount - 85
boom width - 65
" length - 1540
Height at center from ground - 600

Distance between outside of the booms:
front - 330
rear - 585

If something is not clear I will hear from you.

Don Wagstaff
