At this point we recommend that you run a 1/4 yard yield test. You must have a box that is 1/4 cubic yard.
You can build one with internal dimensions of 36" x 3T x 9". You start the unit producing concrete. Stop
both the conveyor and mixer at the same instant. Set the 1/4 cubic yard yield box under the discharge.
Start the mixer and conveyor at the same time. Run the unit to the amount indicated
for 114 cubic yard (1 /4th of the meter count per cubic,yard from step 1). Shut off the mixer and conveyor at the
same instant. The box should be full. It may be necessary to adjust the aggregate gates slightly to adjust
the yield. i
1/4 Yard Count 135
* If you have a water recording meter your lbs./Count will be approximately 1.0425.
