I am talking about the steel carts you tow behing the Cub Cadt LTX 1045 or something of that type. Are they standard and one brand will work with another brand Lawn Tractor? If I see one at a flea market, garage sale, or Craig's List, I could buy it and be sure it will work with about any popular LT? I know I can buy one a Lowe's or Home Depot, but I figured I could save some money and buy one locally. But will it fit?
