2. An Adjustable Solid Stop is provided  
to allow the operator to adjust the  
Gauge Assembly (22) to the desired  
opening, allowing the correct amount  
of material to fall onto the Turning  
Plate (16) for disbursement. The  
“Solid Stop” will allow the operator to  
repeat the opening/closing without  
having to look at the control while op-  
erating the vehicle. It is set by using  
the Thumb Wing Nut (24) located on  
the Gauge Assembly (22). Establish  
the correct opening, then lock down  
the Thumb Wing Nut (24).  
How to Attach to your AtV  
1. Place the ATV Spreader (assembled),  
centered on the front, or rear luggage  
rack of your ATV. Use the J-Bolts  
(34), Press Plate (33) and Hex Nuts  
(32) to connect Frame Rail (21) to the  
luggage rack cross bar closest to the  
seat, or handlebars. Use the J-Bolts  
(34), Press Plate (33) and Hex Nuts  
(32) to attach the Spreader to the  
luggage rack, securing it to the outer  
most rail on the luggage rack.  
2. WARning: Prior to each use, inspect  
the mounting hardware and the ATV  
Spreader to ensure the tightness of  
the mount. If any hardware is loose,  
tighten securely before using the unit.  
3. Measure off a distance of 50 feet on  
the surface you will be working. See  
number 9 below.

re-weigh the material. By taking note  
of how much material you used and  
how wide the spreading area was,  
you can figure the correct rate of  
spread. This will help you maintain  
the correct spreading rate for your  
project.

ment or binding of moving parts,  
cracked or broken parts, damaged  
electrical wiring, and any other condi-  
tion that may affect its safe operation.
