beenthere, I don't know if there is a connection, but I bought the saw from the local John Deere dealer. Maybe I should stop wearing my Kubota hat into his store...... He doesnt know much about the tractors he tries to sell either. He's probably too busy attending his state-wide price fixing meetings to learn about his products.......Egon, you are right! I probably don't have the right screwdriver. Then there is that weird little special chain saw tool which disappears immediately. The genius dealer first told me that the chain spun at idle because the chain was too tight or too loose, I forget which. He pointed to a little unmarked screw hole to adjust the chain. Well, I dont know what that screw hole does, but it doesnt do much to the chain. I found out you have to untighten the bolts on the thing just to loosen the chain (which seems to stretch or change lengths, magically and randomly, all the time). Then you need the weird tool to untighten the bolts. But the tool has been lost, of course. Back to the genius dealer who charges me $7.50 for another weird tool. Later, I see the same tool in the Baileys catalog for about $3.50. I also see the chainsaw, the hardhat and chaps much cheaper than what I paid the Deere dealer........ My conclusion is don't buy nontractor items from a Deere dealer. Everything is wildly overpriced........
