Went with the new 9hp force blower this year, only had about 5-6 hrs on it as of yesterday. About 1pm, finishing up 3rd job of the day with the helper, fan starting making nasty noises & quickly had to shut it off. Didn't look like anything had been caught in it, so dropped off at dealer to check out. Dealer called after they checked it out, said that the fan was defective & a recall was in effect for all of the force blowers that are out there. Apparently a weld on the fan was not holding up & they are causing it to rub in the air chamber. He repaired it good enough for me to use(gotta love that) & they have a new one ordered, will be in next week. Just a heads up to anyone else that has them, get it checked while under warranty.
