Before attaching the snowplow blade, clean and remove any debris or corrosion from the moldboard that might interfere with a tight assembly.
Tip 2: Repair-
The moldboard acts as the support for the cutting edge. If the moldboard has been shortened from wear and tear, the backward blade torque will be increased, resulting in bolt and blade damage and/or breakage.
Tip 3: Bolts-
Use Grade 8 Plow Bolts- Our Grade 8 heavy-duty domed head design made of alloy steel is proven to have an excellent strength to toughness ratio. With the square neck and counter sunk head design, our bolts will hold your blade firmly in place and distribute the load over a larger area.
To reduce bolt failure and blade chatter, use Number 3 head plow bolts with self-locking nuts.
Tip 4: Nuts-
Use Grade 8 Nuts- Our Grade 8 Nuts are hardened to prevent flattening in use. Lock Nuts lock to the bolt (preferred).
*If using standard Grade 8 nuts, double up!
Tip 5: No Lock Washers-
Lock washers are harder than the moldboard. If used, they will gouge the backside of the snowplow moldboard. These washers act as a cutting tool causing unwanted metal shards on the moldboard, and no matter how hard you tighten the nut, the metal shards will flatten. This causes the nut to loosen and will eventually shave/cut off the bolt. The hardened lock nut will prevent this from happening.
Tip 6: Proper Torque Requirements-
Over-torque- causes heads to pop off. Under-torque shears the bolts due to moving blades during use.
