My 20yr old 955 did, but so does my brand new tractor so I'd say it's normal. I've read plenty of other comments about blue smoke with 955's so you're not alone, but I can't remember if people said it was a problem. The colder it was, the louder the HST whine on mine and it never really went away but it did get quieter as it warmed up. Nice tractor, have fun.
