Tractor winterization: the pre-winter storage checklist

Whether the tractor sleeps all winter or is used only occasionally, proper storage avoids unpleasant surprises: dead battery, frozen circuits, degraded fuel, corrosion. Here is the checklist for worry-free wintering (after fall work preparations).

Cooling system: check the antifreeze

This is the point not to neglect at all: coolant that is too diluted can freeze and crack the block or radiator. Check the antifreeze concentration (sufficient protection for your region) and the condition of the fluid. See tractor coolant.

The battery

Cold puts batteries through a rough time. Disconnect it (or put it on a maintainer), store it charged in a temperate place if possible, and clean the terminals. A discharged battery that freezes is headed for recycling.

Fuel (diesel)

Fill up before wintering: a full tank limits condensation (thus water in the circuit). In very cold areas, "winter diesel" prevents paraffin waxing. Purge the water separator if the tractor is equipped with one.

Fluid levels and lubrication

• Oil change if due: better to winter with clean oil (see intervals and oils).
• Lubrication of all points (joints, lift linkage): grease protects against corrosion during shutdown.
• Hydraulic circuit: level and condition.

Physical storage

• Tires inflated to proper pressure (prevents flat spotting); if possible, reduce the weight load.
• Dry, covered location; failing that, a breathable tarp.
• Exhaust and intake protected from rodents (a rag to be removed before starting).

Before putting it away

A final complete cleaning removes dirt and corrosive residues. Complete with the seasonal maintenance check.
