It might be the pipe dope type sealant-it was white, so it could've been that.The dealer came and picked it up today to check out my concerns-I gave them a written list. Overfilled coolant,leaking lift cylinder,and the coolant leak that has now disappeared(of course). It was leaving a small puddle after it was first started and idled for a few minutes,I could not see where it was coming from. I ran it on Monday to see if it still was doing it,but it wasn't. I could smell coolant as it was running. I'll go to dealer in morning and see how much a back blade and landscape rake would cost,if they could do a better price if I bought both. Last windstorm caused a helluva mess and I really don't feel like handraking it all this year,so I just started looking at rake prices tonight.I think salesman told me about $450 for a 5' back blade a couple months ago.
