Storing lawn equipment in unheated sheds during winter
By My Yard Editorial Team · 7/28/2026
The Quick Answer
Unheated storage is fine for engines if fuel is stabilized and the machine is clean and dry. It is not fine for lithium batteries, liquid chemicals, or hoses — bring those inside.
The Witty Breakdown
Condensation is the real enemy. Metal in an unheated shed sweats through every freeze-thaw cycle and rusts from the inside of the deck outward.
Store equipment off the concrete floor on pallets or shelving; concrete wicks moisture upward all winter.
Step-by-Step Fix
- 1
Clean and dry every machine before storage — wet grass under a deck rusts fast.
- 2
Stabilize fuel or run tanks dry.
- 3
Bring lithium batteries, herbicides, and hoses indoors.
- 4
Elevate equipment off the floor and cover loosely with a breathable tarp.
Pro-Tip / Do Not Do This
Don't wrap equipment in plastic sheeting. You'll trap condensation and create a rust incubator with a nice cover on it.
