No...and the old ones were perfectly balanced. Seems like the deck starts off a little noisy...probably acceptable but a few minutes in and the rest of the mowing it seems like a sort of patterned rumble starts up. Wish there was another one around here I could compare to. Will continue to run and monitor and maybe take it to the dealer this fall. Suppose I could pull the covers for a mowing and feel all the brgs looking for a warm one or one w/a growl too. The heat is getting our grass thinned down to....maybe a little thicker "crop" would "load up" the deck drive and quiet it down too?
