I have an 07' Dixon Kodiak 52"/19hp Kaw I noticed the other day that the wheels fealt was if they were dragging, this happened on a few yards with different types of grasses and terrain. More than enough to make me worry, I decided not to use it until I had a remedy. I am thinking that it could be trash in the hydro system, but not sure how it 'appeared' there. I have never done this myself, and my dealer has since folded. I dont have a part# for the filter and was hoping someone could help me with a part # and manufacturer of the correct filter to use on my Hydro system. I would prefer a Wix filter, but anything you guys have will be greatly appreciated.
