When summer heat rolls through Middle Tennessee, it doesn’t just make the air feel thick — it can take a toll on your equipment, your land, and your own body. Whether you’re managing a ranch, tending to your property, running a landscaping crew, or running machines for commercial work, operating in 90°F+ heat isn’t just uncomfortable — it can be dangerous if you don’t prepare right.
At Harris Trading Company, we’ve seen first-hand what happens when gear isn’t prepped for the summer grind. Overheating engines, warped seals, burnt-out fluids, even cracked tires. It’s not pretty — and it’s not cheap.
That’s why we put together this long-form guide to help you keep your machines running and your body protected when the sun won’t let up. From preventative maintenance to safe storage, we’ve got your back.
🌡️ 1. UNDERSTAND WHAT EXTREME HEAT DOES TO MACHINES
Heat is a silent killer — especially for engines and hydraulic systems.
When the temperature climbs over 90°F:
- Engines run hotter. Without proper cooling, temperatures can spike and cause head gasket failures or even total engine burnout.
- Fluids evaporate faster. Coolant, oil, and hydraulic fluid degrade faster, reducing lubrication and increasing friction.
- Belts and seals expand. This can lead to misalignments, leaks, or even breakdowns.
- Tires expand and lose pressure stability. Rubber compounds weaken over time when exposed to direct sun.
- Electrical components suffer. Wiring, batteries, and sensors can overheat or corrode more quickly.
If your machine isn’t prepped — it’ll show you quickly.
🔧 2. SUMMER MAINTENANCE CHECKLIST FOR EQUIPMENT
Before temperatures hit 90°F and above, run through this heat-specific checklist on every machine you operate.
✅ Engine Cooling System
- Check radiator for clogs, bent fins, or dust buildup.
- Flush and refill coolant (use a 50/50 coolant-water mix or Yanmar’s approved blend).
- Inspect hoses for bulges, cracks, or leaks.
- Test radiator cap pressure (a weak cap leads to overheating fast).
✅ Oil and Hydraulic Fluids
- Check levels weekly — not just monthly in the summer.
- Use high-temp-rated oil. Talk to us about summer blends.
- Inspect hydraulic lines for wear or drips.
- Replace filters more frequently if working in dusty areas.
✅ Air Filters
- Clean or replace them weekly in dusty or dry areas.
- Consider upgrading to heavy-duty filters if working on job sites.
✅ Battery
- Keep terminals clean and tight.
- Avoid storing batteries in direct sun.
- Test voltage often — extreme heat shortens battery life by 50%.
✅ Belts, Hoses, and Seals
- Look for fraying, soft spots, or oil buildup.
- Heat makes rubber fail — and one broken belt can shut you down mid-job.
✅ Tires
- Check pressure before use when tires are cool.
- Keep tires shaded if parked for long periods.
- Rotate if sitting for over two weeks.
🛑 3. SIGNS YOUR MACHINE IS STRUGGLING IN THE HEAT
Stay alert for these red flags:
- Temperature gauge spikes or warning lights
- Sudden drops in power or sluggish performance
- Steering becomes stiff or unresponsive
- Hydraulic function lags or gets jerky
- Strange burning smells or visible steam/smoke
- Frequent stalling or unexpected shutdowns
👉 If you notice any of these, stop the machine immediately. Let it cool down. Check your fluids and consult a tech.

🧊 4. STORAGE & SHADE: KEEP IT COOL
Where you store your machine matters — especially in the heat.
If you don’t have a climate-controlled barn or metal building, here are a few other ideas:
✅ Use Equipment Canopies or Portable Garages
Invest in:
- Shade sails
- Pop-up garages
- Heavy-duty tarps with UV protection
(Hint: we’ve got options at HTC — just ask.)
✅ Rotate Machine Use
If you have multiple machines, alternate use so one isn’t getting sun exposure all week long.
✅ Keep Fuel Out of the Sun
Store diesel and gas containers in cool, shaded areas. Heat = faster evaporation + increased pressure = fire risk.
✅ Apply UV Protectant to Tires & Seats
Products like 303 Aerospace Protectant or other silicone-based sprays protect rubber, vinyl, and plastic.
🧽 5. CLEANING & SUMMER CARE TIPS
Dirt and grime can act like an insulator, trapping heat.
- Pressure wash your radiators and grills often to keep airflow strong.
- Wash caked-on grease from joints and undercarriage.
- Clean windows and mirrors — hazy visibility in summer light is dangerous.
- Inspect your machine after every job for debris caught in moving parts.
Bonus: Keeping your equipment clean also helps you spot leaks or damage before they become costly repairs.

🧍♂️ 7. DON’T FORGET THE OPERATOR: HOW TO PROTECT YOURSELF IN THE HEAT
Caring for your machine doesn’t matter much if you overheat.
Signs of Heat Stress:
- Headache, nausea
- Confusion, dizziness
- Fatigue or chills
- Muscle cramping
- Dry mouth or dark urine
If you’re pushing yourself to finish the job, remember this: a breakdown of your body will cost more than a delay.
Top Tips for Working in High Temps:
✅ 1. HYDRATE BEFORE, DURING, AND AFTER
- Drink at least 16 oz. of water before the job.
- Sip water every 15–20 minutes on the job, even if you’re not thirsty.
- Avoid caffeine — it speeds up dehydration.
✅ 2. WEAR BREATHABLE GEAR
- Use moisture-wicking shirts (long sleeve, light color).
- Hats with brims & neck flaps help.
- Polarized sunglasses protect your eyes from sun glare on metal.
✅ 3. TAKE SHADE BREAKS
- Set a timer if you tend to work non-stop.
- Use your truck, a tent, or the shade of a barn to rest.
✅ 4. COOL DOWN YOUR CAB
If you’re in a cabbed unit, crack the windows before entry. Consider tinted windows, mini fans, or sunshades.
✅ 5. EAT RIGHT
Avoid heavy meals during peak sun. Stick to light snacks like fruit, trail mix, or granola bars.

🧯 9. FIRE SAFETY FOR SUMMER JOB SITES
Dry grass + metal heat = danger.
🔥 Fire Prevention Tips:
- Keep fire extinguishers in all machines and work vehicles.
- Avoid refueling in direct sun.
- Let engines cool 10–15 minutes before cleaning or topping off.
- Don’t park hot machines over dry brush or tall grass.
- Check PTO areas and engine bays for debris.
One spark can lead to a full-blown brush fire — don’t risk it.
