When checking the oil level, which part on the dipstick should have oil on it in order to indicate that the oil level is correct?
Show the correct answer
Correct answer
C. Below the "MIN" level.
Explanation
In the photo, the tip of a dipstick with notches that mark the measuring range. An incorrect oil level is shown by an oil mark below the "MIN" mark - answer C.
The MIN mark shows the smallest amount of oil at which the pump can still reliably draw it from the sump. Below this limit, especially when the tractor works on a slope or brakes hard, the oil moves around in the sump, the pump may suck in air and the oil pressure drops for a moment. The bearings then run almost dry and wear quickly. An oil mark slightly below MAX (answer A) and one between the marks (answer B) mean a correct level. Oil loss usually has a cause - a leak, worn piston rings or simply checking too rarely - so after topping up, check the level more often and watch whether stains appear under the tractor.
