How to Keep Your Tractor Cool This Summer
As temperatures rise across New Zealand, tractors and farm machinery are put under extra strain. Long working days, heavy towing, and dust-filled paddocks can all take a toll — especially on your cooling system. Overheating is one of the most common causes of tractor breakdowns during summer, but with a few simple checks and regular maintenance, you can keep your machine running smoothly all season long.
Check Your Radiator and Cooling System
Your radiator is your first line of defence against overheating. Before the summer workload ramps up, inspect it for any blockages, leaks, or corrosion. Dust, chaff, and insects can quickly build up on the fins, so it’s worth giving it a good clean using compressed air or low-pressure water. While you’re there, check your coolant level and make sure it’s the right mix for summer conditions.
Inspect Hoses and Belts for Wear
Cracked or worn hoses and loose belts are small issues that can quickly become major problems in hot weather. Look for any soft spots or visible wear, and replace parts that show signs of ageing. Keeping a few spare tractor hoses and belts on hand from AgSpares is an easy way to avoid downtime if something gives out mid-season.
Keep an Eye on Oil and Fluid Levels
Engine oil, transmission fluid, and hydraulic oil all play a part in temperature control and lubrication. As the workload increases, check levels regularly and top up or change fluids as needed. Using good-quality lubricants not only helps reduce friction but also extends the life of your engine and key components.
The AgSpares website has a number of workshop manuals available which will specify the type of lubricants needed – a word of warning, make sure you select the right viscosity (e.g. 15W-40) for your make and model tractor.
Clean Air Filters to Maintain Performance
Dusty summer conditions can quickly clog your air filter, making your tractor work harder and run hotter. Cleaning or replacing the filter regularly helps your engine breathe easier and operate more efficiently. AgSpares offers a wide range of tractor filters NZ to suit most makes and models, so it’s easy to keep a spare or two ready to go.
Don’t Ignore Warning Signs
If you notice your tractor running hotter than usual, a drop in power, or any coolant smell, don’t ignore it. Stop work, let the engine cool down, and check for the cause. Early attention can prevent a costly breakdown and save you valuable time during the busiest months.
If it all sounds a bit daunting you can always download from our website quick reference guides, free e-books or parts catalogues that will help you out.
