When I recently purchased a 2015 550XR from a friend he gave me a Arctic Cat Sprayer with a boom. He told me that it was for a previous Arctic Cat ATV he had before this one and didn't need it anymore. I searched on the web and found the sprayer I think but the boom looks different and does not connect to the hitch receiver. like the current model. I have not tried to mount it yet since it is darn cold now here in PA. I was wonder if Arctic Cat made another model prior to the current one that has a hitch mounted boom. I also don't know how the tank will fit on my SpreedRack II at this point but it looks similar to the current model. I have not taken any photos of it but will the first chance i get.
