Jose,Are all 42 in blades for husquvarna universal.i have no clue what model .It does have the 22 hp twin motor tho.I would prefer mulching blades.Thx,GREG
They are, but they aren't. The reason why I say this is there are some limitations when it comes to these blades. The 2008 models and older are going to have a different setup and fit differently. Another difference is if you have a fabricated (welded) deck instead of a stamped deck. The blades would be different. From what you are describing about your mower, it sounds like it is a YTH22V42, if this is the case and it is a 2009 or newer, then you should be able to use the Gator Blades model 596-900 with your mower. I would suggest taking a look at the part number on the serial tag sticker under your seat and let us know what that is and we can confirm, but as I said it does sound like you own a YTH22V42 and if this is the case, these will fit if it is a 2009 or newer.
