Product description
Alternator for Yanmar 3TNV76, Yanmar 3TNV84, Yanmar 3TNV88, Yanmar 4TNV88 engines with a voltage of 12V and a rated output of 55A.
The alternator is a device that converts mechanical energy into direct or alternating current, thereby supplying power to the tractor's electrical system, including the battery. The alternator generates current only while the engine is running and is driven by a V-belt. The first signs of alternator failure are a battery charging warning light that does not go out, flickers or does not light up at all while the glow plugs of the tractor engine are heating. On the other hand, if the light comes on while the tractor is working, it may mean that the alternator is supplying the wrong voltage to the battery.

Questions & Answers
Why is regular filter replacement (oil, air, fuel) crucial for a mini tractor?
User
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
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
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.
