How To Store Your Machinery Over Long Breaks: A Coffs Harbour Salt-Air & Wet-Season Guide

Storage preparation should match the duration of the layup:

• Under six weeks: Minimal prep is the right call. Top up the fuel tank, apply grease to exposed points, connect a battery tender and park it under cover. A full storage prep for a six-week break is overkill.
• Six weeks to three months: Worth treating seriously. Fuel top-up with a diesel stabiliser, full grease service, battery tender or disconnection, hydraulic ram protection and a fluid check. Two to three hours of preparation now is worth considerably more than the recommissioning time later.
• Three months or more: Full pre-storage service. Oil and filter change, fuel treatment, full grease, battery removal or tender, hydraulic ram protection and implement storage handled separately. At this duration, Coffs Harbour's coastal environment will find any gap in preparation.

In a coastal humid subtropical climate, machinery sitting without preparation accumulates problems sooner than in a dry inland environment. What the Cook Drive workshop regularly sees after an unplanned long layup:

• Sulphated batteries — self-discharge and sulphation begin without a tender; sulphated batteries often can't be recovered through a standard charge
• Microbial diesel contamination — a half-empty tank is a condensation trap; water in diesel creates conditions for microbial growth that blocks filters and damages injectors
• Seized hydraulic rams and perished hose ends — exposed chrome on extended rams is particularly vulnerable to surface rust in salt air
• Rodent damage — wiring looms, rubber hoses and insulation are attractive nesting material; a mouse-damaged loom on a modern tractor is an expensive repair
• Flat-spotted tyres — tyres supporting full machine weight in one position for months develop flat spots that may not recover

This is what separates coastal storage from inland storage. Salt-laden air combined with wet-season humidity means condensation forms on cold metal overnight even under a roof — conditions a generic storage guide doesn't prepare you for.

Practical steps for the Coffs Harbour environment:

• Grease all exposed points thoroughly — PTO shaft splines, linkage pins, lift arm pivots and cutting deck pivot points, not just standard service points
• Coat exposed unpainted metal — a lanolin-based spray, penetrating oil or corrosion inhibitor on any bare metal surface
• Protect hydraulic ram chrome — retract all rams where possible so the chrome rod sits inside the cylinder; where that isn't possible, coat exposed chrome with hydraulic grease
• Consider shed ventilation — a fully sealed shed in Coffs Harbour's humid climate can trap more moisture than an open one

When perished seals or hoses need replacing after storage, genuine parts protect performance and safety far better than a generic substitute — particularly for hydraulic seals where specification matters for operating pressure and fluid compatibility.

Under six months: Fill the tank and add a diesel stabiliser. A full tank has minimal air space, reducing condensation and microbial contamination risk.

Over six months: Run the tank as low as practical before shutdown, treat the residual fuel and add fresh stabilised fuel on recommissioning. Diesel deteriorates over time and a half-empty ageing tank is a liability.

Oil change — before or after storage? Before. Used engine oil contains combustion acids and moisture that continue affecting internal surfaces while the machine sits. Fresh oil going into storage protects against that.

The simplest way to avoid all of this is to book a machinery service before the machine goes into the shed, not after it refuses to start.

Battery: Disconnect it for any layup over a month, or connect a battery tender — a low-current maintenance charger that keeps the battery in good condition indefinitely. NCCE stocks batteries for most machines it services; if the battery won't hold charge on recommissioning, replace it before it leaves you stranded.

Hydraulic fluid: Hydraulic fluid absorbs moisture over time. For a long layup, check condition and change it if overdue — fresh fluid protects seals and internal components better than degraded fluid.

Greasing: Do a full grease service at the start of the layup across all service points. Don't wait for recommissioning day.

Implements often get less care than the tractor and arrive back in the workshop in worse shape.

• Store implements off the tractor where possible — leaving heavy attachments on the three-point linkage for months stresses lift arms and top links
• Slashers and mowers: Clean off organic material before storage; decomposing grass holds moisture and accelerates corrosion on blades and gearboxes
• Rotary hoes and rippers: Remove soil from tines and frames; coat exposed metal on ripper points
• PTO-driven implements: Disconnect and grease the PTO shaft at both ends; store it supported rather than hanging

Filters, belts and a spare battery are all spare parts worth keeping on hand especially if you're bringing a machine out of storage on a weekend when the workshop is closed.

Before starting: check engine oil, coolant and hydraulic fluid levels; inspect hoses and belts for cracking; check tyre pressures; look for rodent activity in the wiring loom; inspect exposed hydraulic ram chrome before extending.

On first start: idle for several minutes before applying load; check for warning lights or unusual sounds; test all hydraulic functions slowly; check for fluid leaks after the first run.

North Coast Construction Equipment has been servicing the Mid North Coast from the Cook Drive workshop since 1992 — covering Coffs Harbour, Grafton, Nambucca Heads, Macksville, Dorrigo and Kempsey. If you're heading into a long layup and want the machine properly prepared, or bringing something out of storage that isn't starting cleanly, our team is here to help. We service DEUTZ-FAHR, Kioti and JCB machines as well as many others. If a long layup has finally convinced you the old machine isn't worth recommissioning, we've been supplying tractors in Coffs Harbour for more than three decades and can talk through realistic alternatives without pressure.
