Fenders can stay on, but you will need either chains or ag tires to plow, no way around that. 6-12 ags are not real expensive, if you dont have a local source like TSC or Rural King, you can order them from ebay sellers or M.E. Miller Tire over in Ohio. Put some 6-12 ags on the back, your rear wheel weights and you should be set. Originals usualy dont need front weights if the plow is set up correctly. When you plow, if the plow wants to make the tractor swing into the plowed area of the field, its not set correctly. When they are set inline with the tractor and not swung to one side or the other, you will be able to hold the right front tire up against the furrow wall with just a little steering input toward the left. The plow must be straight in relationship to the tractor frame, thats what those two large set bolts on the brinly adapters are for, so the plow can be lined up straight and locked down tight. The plow will have a cant to one side, thats so when the tractor is canted over in the furrow, the plow will be straight up and down. There will be plenty of help there from seasoned plowers to help out on set up. Have a great time! Mike
