You divide by 3600 - since an hour has 3600 seconds.
This tractor can reach the max speed of 20 km per hour.
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.
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)
10 to 15euro per hour.
