Installing a static charge grounding kit
Hi, this is Wayne from Sears PartsDirect. Today we're going to install a kit to help prevent shocks from static electricity that builds up in your snowblower chute during the cold winter months. Before you start, park the snowblower in a level area and remove the ignition key. Allow the engine to cool. Use a 1/2-inch socket to remove the lock nut from the tilt mechanism on the chute. Install the larger stud terminal of the grounding harness onto the bolt. Install a washer on each side of the harness terminal connector, then reinstall the lock nut. Tighten the lock nut firmly so that the terminal doesn't rotate with the tilt mechanism.
Connect the other end of the grounding harness to the muffler shield bolt on the lower left side of the engine. Carefully bend the barrel of the terminal away from the muffler shield so that the cable isn't resting against the shield. Secure the grounding harness loosely to the chute support bracket using a 7-inch cable tie. Mark the grounding harness 18-inches from the tilt mechanism terminal. This will be the location of the farthest cable tie from the terminal. Connect the grounding cable to the front tilt cable using a 4-inch cable tie, leaving enough slack in the grounding cable to allow free movement when adjusting the chute tilt. Install 3 more evenly spaced cable ties along the grounding cable and front tilt cable to secure them together. Trim the loose ends from the cable ties.

Frequently asked questions about snowblower static discharge
Why do snowblowers build up static electricity?
Cold, dry winter air creates the perfect conditions for static buildup. As snow moves rapidly through the plastic chute, friction creates an electrical charge. Without grounding, that charge can build up on the chute and discharge through the closest conductive path - often your hand.
Is static shock harmful to the snowblower?
The shock isn’t harmful to the equipment, but it can be unpleasant and distracting for the user. In rare cases, static discharge can interfere with sensitive electrical components.
Do all snowblowers need a grounding kit?
Not always. Some snowblowers already have grounding built in. Others only experience static shocks during extremely dry, powdery snow conditions. If shocks are frequent or severe, adding a grounding wire is an effective solution.
Can I make my own grounding harness?
Yes. Many owners create a simple grounding strap using standard electrical wire, crimp-on ring terminals, and heat-resistant cable ties. Just make sure the wire is secured safely away from moving parts and heat sources.
Are there other ways to reduce static shock?
Yes. These steps can also help reduce static buildup:
Avoid clearing extremely powdery snow at high chute speeds.
Keep the chute clean of ice and debris.
Use a silicone-based nonstick spray such as Snow-Jet in the chute to reduce friction.
