Using this multi - purpose spreader is easy. First, connect it to your skid steer or tractor with the 2″ trailer receiver. Then, fill the heavy - duty poly hopper with the material you want to spread, like salt, fertilizer, or seeds. Use the variable speed controller to adjust the spread width up to 40 feet for an even spread. When you're done, use the quick disconnect on the wiring harness to remove the spreader easily. For pelletized materials, you can add the optional vibrator or gate kit. As for maintenance, keep the hopper clean after each use. Check the wiring harness regularly for any damage. If you use the optional kits, make sure they are properly attached and functioning. Avoid overloading the hopper beyond its 4.75 cu ft capacity and 460 lbs weight limit.
