Your AccuGreen 3000 Drop Spreader was calibrated at the factory. However, a spreader's calibration may change or slip over time or during periods of heavy use.
You may check the calibration of your Scotts Accugreen 3000 by first adjusting your micrometer setting to 6. Turn the spreader over so that you are looking at the outside of the bottom of the hopper. Use your foot to hold down the trigger (if your trigger has a locking mechanism you can lock it in place prior to turning upside down). With the micrometer set at 6 and the trigger squeezed against the handle, the front edge of the projecting ridge on the shut-off bar should be aligned with the calibration line located on the 2nd or 3rd tooth from the center. Some of the older AccuGreen 3000 Drop Spreader spreader models do not have a raised ridge. On these spreaders, line the front edge of the shut off bar to the calibration line.
To adjust the alignment, use a small wrench to turn the black calibration screw at the lower end of the control wire leading from the micrometer rate setting barrel. Adjust the screw until the calibration line and raised ridge or front edge of the shut-off bar meet. If you have any difficulty checking or adjusting the calibration, contact us and we will be happy to help walk you through the adjustment.
Again, thank you for taking the time to contact us and for your interest in Scotts. Please feel free to call us at 1(800)5438873 anytime we may be of assistance.
