What should I do to prepare my lawn mower for winter storage?

Before storing your lawn mower for the season, it’s important to perform a few key maintenance steps to protect your equipment and ensure a smooth start in spring. We recommend:
•Cleaning the deck and blades to remove grass buildup
•Changing the oil and replacing the air filter
•Adding fuel stabilizer or draining the fuel tank
•Sharpening the blades
•Checking spark plugs and battery (if applicable)
•Bring your mower in for a full end-of-season tune-up, and we’ll take care of everything so it’s ready to go when the grass starts •growing again.

What kind of maintenance does my snow blower need before winter?

To make sure your snow blower performs reliably through Wisconsin’s snowy months, we recommend a pre-season inspection that includes:
•Checking and replacing spark plugs
•Inspecting belts and auger for wear
•Changing the oil and checking fuel lines
•Ensuring proper tire pressure or skid shoe alignment
•Testing the electric start and throttle response
•We service all makes and models and offer quick turnaround times—so you’re not caught off guard by the first snowfall.

Do you offer pickup and delivery?

Yes! For your convenience, we offer pickup and delivery services so you don’t have to worry about transporting your equipment.

Can I bring in my equipment for a seasonal tune-up?

Yes, we offer maintenance services including seasonal tune-ups and pre-season inspections to keep your equipment in top shape year-round.
