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 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.
