I have a 1655 that has been  hard to start, shortly after I got it  I put in a fleet farm battery it would start OK above about 40 degrees but colder than that I had to use the block heater recently I bought a new battery made by Exide{from the local john deere shop} now she starts in 20 degree weather without any help good batterys make a HUGE difference dont put in the elcheapo batterys unless you are going to sell it soon <!-- s:o --><img src="{SMILIES_PATH}/icon_surprised.gif" alt=":o" title="Surprised" /><!-- s:o -->
