Drop Size Adjustment & Calibration
Initially set the Feed adjustment plate to setting 4, as indicated by the arrow on the drop adjustment plate.
To adjust, loosen BOTH hand wheels, and slide the unit forwards or backwards to the desired value. Tighten
securely.
Setting 1: Minimum drop size
Setting 8: Maximum drop size
Fill the hopper 50% full of the feed to be distributed. With the machine attached to the towing vehicle and
on level ground, switch the control box on and deposit 10 drops of feed into a bucket. Measure the weight of
the deposited feed, and divide by the number of drops (in this case 10) to give the weight per drop.
Adjust the feed adjustment plate as required to increase or decrease the drop size, checking after each ad-
justment for the average drop size. Individual drop sizes can vary, especially with large granular materials
(eg. cobs) or with feedstuff containing molasses, so it is important to average the drop size over a number of
drops.
It is recommended that the feed be deposited in round numbers, ie. 1kg, 1.5kg, 2kg etc. This allows easy
calculation of required number of drops for different livestock numbers.
The drop setting will differ between feedstuff, due to the different particulate size and any binding agents
such as molasses. Its is strongly recommended to re-calibrate if you change feed make-up or consistency.
Once you have set the machine to the desired drop size, securely tighten the two retaining handwheels to
ensure this does not change during use.
