This is a continuation of my problem below (03-21-09) regarding john deere 300 not starting in spring .
Dealer said I should try changing spark plugs before they come to pick it up to see what is wrong with it... my tractor is only 1 year old, is it normal that the spark plugs could be bad? And need replacing?
How could I tell if spark plugs are bad?
I live in northeast, so it is just starting to get a little warmer.
