john deere tachometer not working

• 2023-02-14

The reason why the john deere engine tachometer not working : if it is a mechanical tachometer, it may be that the transmission core wire is broken. At this time, only one transmission core wire needs to be replaced. The engine speed is related to the work done per unit time or the effective power of the engine , that is , the effective power of the john deere engine changes with the speed . Therefore , when interpreting the effective power of the engine , the corresponding speed must be indicated at the same time . The effective power and its corresponding speed specified on the engine product label are called the rated power and rated speed respectively. The working condition of the john deere engine at rated power and rated speed is called rated working condition . The rated power is not the maximum power that the engine can emit , but the maximum use limit of the effective power determined according to the purpose of the engine. When the same model of engine is used for different purposes , the rated power value is different . The effective torque also varies with engine operating conditions . Therefore , the maximum torque that the automobile engine can output and its corresponding speed are used as indicators to evaluate the engine power . The engine speed can reach 700 rpm at idle speed and 3000 rpm at normal operation .

We drive at a gear change speed of no more than 4000 rpm, that is to say, we seldom use it above 4000 rpm. When most john deere are running normally, the speed will generally be kept within 2000 rpm, and the upshift is also completed around 2000 rpm. In theory, high speed also means that the car releases more power and accelerates faster, but almost every car has a red area on the tachometer? Have we noticed the tachometer of our car? Generally, there are about 8000 turns in total, and the red line area is reached after 7000 turns. This is a speed warning line.

The john deere engine can't bear to drive at high speed for a long time. This is because modern automobile materials and other components can't bear to work in this high strength state. Except for a few high-performance vehicles that can be processed by special technology, most civil vehicles can't do it.
