PERFORMANCE DATA

The volume of dirt removed is V = W x d x L, where W is the drum width, d is the depth of cut and L is the length of the shoulder worked on.

Example: 6' width x 0.5' depth x 5280' length = 15,840 cubic feet or 587 cubic yards

1 cubic yard = 27 cubic feet = 46,656 cubic inches

 

The dirt removed per inch and per foot of depth and for a 100 foot long shoulder is:
Drum width (W) 40" 48" 60" 72"

d = 1' 1 1.2 1.6 1.8 (cu. yd.)
Volume (V)
d = 12' 12 14.5 19 22 (cu. yd.)

At the recommended advance speed of 4 MPH, the dirt removed per hour is:
Drum width (W) 40" 48" 60" 72"

d = 1' 211 253 338 380 (cu. yd.)
Volume (V)
d = 12' 2530 3060 4010 4650 (cu. yd.)
At a rotor speed of 300 RPM, the tip of the digging tooth moves at 30 MPH.
