PJ or any Bac Vac user. I've noticed in some pics of the Hustlers using the Bac Vac the mowers have weights attached to the front castor mounts. Is this included w/ the unit or is it an option? I didn't see it included in the new price list for '05. I'm waiting on one that has been ordered for about a week and I've got a lot of slopes. I demo'd a Toro Z last year w/ a modified PECO (I think) and w/out the weights installed it would "wheelie" once the hopper started to fill up. Thanks for any help.
