I like that, I use a 1969 Lawn Boy, bought new in 1974, that has mowed
1/2 acre of grass every two weeks for most of its life. It is on its third
spark plug fourth blade and still starts on the second pull. Now you tell
me that when it dies I will be foreced to join the two year cycle instead of
the two cycle? <G>
