I have an 09 Ranger 2wd with 143hp Mazda 2.3 4 cylinder, 5 speed manual and 3.73 rear axle ratio. I have a factory class 3 frame hitch on it. I am wondering how much I can tow with it? I'm hoping I can pull my Toro 117 Groundsmaster with 52" deck and Toro 520xi with 60" deck on a trailer. I am thinking of building a trailer mostly from steel I have sitting around. I am parting out a 93 F150 2wd and am planning on using the front spindles/hubs and build an axle from it. I was also planning on using the rear springs from the truck. I am considering using hydraulic surge brakes on it.
