Product description

Thermostat for Kubota tractor with dimensions 43 x 40 mm, opening temperature 71°C fits Japanese Kubota tractors of the D, L series and others.

What is a tractor thermostat?

The coolant thermostat is one of the most important components of the cooling system and is responsible for controlling and regulating the temperature of the coolant. The thermostat is a device that operates under the influence of increased temperature, and its correct operation allows maintaining the correct temperature needed for the most efficient operation of the engine. When the temperature of the coolant rises to a certain level, the thermostat "opens" under the influence of heat, allowing the coolant to pass to the second circuit (radiator), which allows for effective cooling of the fluid, and further on the engine.

First signs of a faulty thermostat?

Engine overheating or very long engine warm-up to the appropriate operating temperature are the most visible symptoms of thermostat damage. Thermostat failure in the closed position causes engine overheating and is very dangerous for the engine, therefore after the coolant temperature warning light comes on, you should stop work as soon as possible and turn the engine off. A less dangerous situation is when the thermostat fails in the open position because water circulating in a large circuit affects the engine's failure to heat up and this is a failure less dangerous for the engine, but in the long run it also has an adverse effect and is harmful to the engine.

Questions & Answers

Why is regular filter replacement (oil, air, fuel) crucial for a mini tractor?

User
Ekspert Traktor.com.pl – Doradca techniczny • 17.02.2026
Regular filter replacement is the easiest way to extend the life of an engine from brands like Kubota or Yanmar. The oil filter removes metallic contaminants generated during operation, the air filter protects the cylinders from field dust, and the fuel filter prevents water and dirt from damaging the precision injection system. We recommend replacing filters every 50-100 operating hours or at least once per season to ensure optimal engine performance.

How to properly select and sharpen mower blades for a Japanese tractor?

User
Ekspert Traktor.com.pl – Doradca techniczny • 17.02.2026
When selecting mower blades, consider the mower deck model and the blade length and center bore diameter. Maintaining blade balance is crucial when sharpening – an unbalanced blade causes vibrations that damage the hub bearings. Remember that sharp blades mean healthier grass, a cleaner cut, and less strain on the engine of your Iseki or Mitsubishi tractor.

How to identify the correct V-belt size and how to care for it?

User
Ekspert Traktor.com.pl – Doradca techniczny • 17.02.2026
It's best to read the markings on the side of the old V-belt. If they are illegible, measure the belt width and its outer length (La). On Shibaura and Hinomoto tractors, it's important to regularly check the belt tension – too loose a belt will cause slippage and faster wear, while too tight a belt can cause alternator or water pump bearing failure.
