Knob Control 532106933

1 To change the blade I lifted up the tractor with a floor jack as far as i could get it and then chocking the rear wheels so the tractor would not roll back.
2 Then with a impact gun and socket I removed the bolts that held the blades in place.
3 Reversing the procedure first starting the retaining bolts by hand I put the new ... Read more blades on the tractor and lowered the machine.
4 For the tune up I took out the spark plug using my 5/8\" long socket.
5 Reversing the procedure I first gaping the spark plug the the proper specs then putting a light coating of Never Cease on the threads of the spark plug and reinstalled the plug first starting the plug by hand so the threads do not cross and then snugging it down.
6 The air filter I just took the old one out and placed the new one in the same way.
7. The Mulching attachment simply following the direction that came with the item and using the hardware provided.

Just screwed on the new knob. Used the extension oil drain to avoid spilling oil on the frame during the engine oil change. Hold it in place while removing the drain plug & let the oil flow into a drain pan.
