The older cat hour meters that were mechanically driven off of the fuel pump counted RPM hours. The newer ones are an oil pressure switch and clock hour for hour time no matter what the RPM if the engine is running.
If you mean the red dot below the digital hour meter, it's telling you that the charging system isn't throwing enough voltage to operate the electric PTO and charge the battery efficiently.
convert 1bar to meter cube per hour
0.0002777 meter per second
You divide by 3600 - since an hour has 3600 seconds.
72,000 metres
1 meter per second = 3.6 kilometers per hour
You can accomplish this by removing one lead from the back of the hour meter. It will be a DC voltage circuit.
This tractor can reach the max speed of 20 km per hour.
you can look at engine wear or drawbar wear to determine if the tractor has had a lot of work or it could have just had a hard life with low hours. there is no way to really tell
1 meter per second = 3,600 meters per hour = 2.237miles per hour. (rounded)
You multiply by the number of feeds per meter and by the number of minutes per hour.
Depends on the size of the tractor and what work it is doing.
