2027 Big Tex 35SA-12 Single Axle Utility Trailer w/ 4′ Ramp, 77″ Width

2026 Big Tex 35SA-12 Single Axle Utility Trailer w/ 4′ Ramp – 77″ X 12′ · Big Tex 35SA-12 – 12′ Professional-Grade Utility Trailer with Tube Rail & 3-Way Gate If you need a utility trailer that’s easy to tow, easy to maneuver and ready to handle everyday work, the Big Tex 35SA-12 is a hard trailer to argue with. This 12′ single axle utility trailer gives you a 2,995-lb GVWR, 2,012-lb factory cargo capacity, 77″ deck width, 2″ × 2″ square-tube top rail and a 4′ three-way rear ramp gate with coil-spring assist. That three-way gate is the real kicker. Use it as a ramp for loading equipment, latch it upright as a conventional rear gate, or fold it down into the bed when you need the extra room for longer cargo. It’s a simple, practical trailer built for homeowners, landscapers, contractors and anybody who needs to haul equipment without dragging around more trailer than the job requires.

Actual trailer weight and available payload can vary with equipment. The VIN/specification label on the individual trailer is the final authority. Features & Benefits 12′ × 77″ Utility Deck The 12′ deck gives you enough room for a wide variety of equipment without making the trailer unnecessarily long. At 77″ wide, there’s plenty of usable deck space for lawn equipment, ATVs, building materials, tools and general cargo while keeping the trailer relatively easy to maneuver around a property or jobsite. 4′ Three-Way Ramp Gate with Coil-Spring Assist This is one of the best features of this particular 35SA-12. The 4′ three-way gate gives you three ways to use the rear of the trailer: Ramp — lay it down for loading wheeled equipment. Rear gate — latch it upright for normal hauling. Fold it into the bed — when you need to carry longer cargo. The coil-spring assist makes raising and lowering the gate easier, too. Big Tex’s current literature specifically describes the three functions of this gate and its ability to fold into the bed for longer cargo. That’s a whole lot more useful than a gate that only knows one trick. 2″ × 2″ Square-Tube Steel Top Rail The 35SA’s square-tube top rail adds structure around the open sides while giving the trailer a more substantial perimeter than a traditional angle-iron top rail. Big Tex specifically describes the square tubing as providing increased strength and structure compared with typical angle top rails. 2,012-Lb Factory Cargo Capacity Big Tex lists the 35SA-12 at 983 lbs empty with a 2,995-lb GVWR, giving it a factory-rated cargo capacity of 2,012 lbs. That provides useful capacity for everyday hauling without starting with a heavy trailer that’s eating into your available payload before you load anything. 3,500-Lb Premium Cambered Axle The 35SA-12 uses a 3,500-lb premium cambered axle with quick-lubricating hubs. The axle is designed for dependable everyday service while the quick-lubricating hubs simplify routine maintenance. Treated-Pine Floor The treated-pine deck provides a durable, practical hauling surface for equipment, materials and general cargo. It’s also easy to work with when adding chocks, tie-down hardware or other accessories for a specific type of load. 17″ Open Sides The 17″ sides provide useful containment without boxing the trailer in. You can still access equipment from the side while having a defined edge around the deck to help keep cargo where it belongs. Four Built-In Tie-Down Loops Four tie-down loops inside the bed give you dedicated points for securing cargo. When hauling equipment, use tie-downs with an appropriate working load limit and secure the load according to the equipment manufacturer’s requirements. 2,000-Lb Set-Back Jack The 2,000-lb top-wind set-back jack is positioned to help keep the jack out of the way when lowering the tow vehicle’s tailgate. It’s a little feature that can save you from discovering the hard way that your truck’s tailgate and trailer jack aren’t exactly friends. Radial Tires & Black Mod Wheels The 35SA-12 uses ST205/75R15 Load Range C radial tires with 15″ black mod wheels. Big Tex specifies steel-belted radial tires for this series, paired with the black wheels for a practical combination of durability and appearance. Electric Brake Ready The factory axle includes brake flanges for easy brake addition, while Big Tex offers electric brakes with a complete breakaway kit as an available configuration. If your particular Old South unit is equipped with electric brakes, verify that the tow vehicle has a compatible brake controller before towing. Who Is the Big Tex 35SA-12 For? The 35SA-12 is a great fit for customers who want a compact utility trailer with more versatility than a basic flat deck. It’s particularly well suited for: Landscapers and lawn-care professionals Contractors and handymen Homeowners Farmers and property owners ATV owners Golf cart owners Small equipment hauling Lawn equipment Landscaping materials Building materials General-purpose hauling The three-way gate makes it especially useful for customers who regularly load wheeled equipment but still need the trailer to function as a conventional utility trailer. Frequently Asked Questions How much can the Big Tex 35SA-12 carry? The 35SA-12 has a 2,995-lb GVWR and 2,012-lb factory-rated cargo capacity. Big Tex lists the factory empty weight at 983 lbs. Always verify the actual trailer’s certification label before loading. How long is the Big Tex 35SA-12? The deck is 12 feet long and 77 inches wide, with a manufacturer-listed deck height of approximately 18 inches. Is the Big Tex 35SA-12 a single axle trailer? Yes. The 35SA-12 uses one 3,500-lb premium cambered axle. Does this 35SA-12 have the three-way gate? Yes. This Old South Trailers configuration includes the 4′ three-way rear ramp gate with coil-spring assist. The gate can be used as a loading ramp, secured upright as a rear gate, or folded into the trailer bed for hauling longer cargo. What makes the three-way gate different from a normal ramp gate? A standard ramp gate generally gives you a ramp when it’s down and a gate when it’s up. The three-way design adds a third function: it can fold into the bed, allowing longer cargo to extend beyond the rear of the trailer. Does the 35SA-12 have a tube top rail? Yes. This trailer uses a 2″ × 2″ square steel-tube top rail with 2″ angle uprights. Big Tex describes the square tubing as an enhanced-strength feature compared with traditional angle top rails. Does the 35SA-12 have trailer brakes? The standard axle has brake flanges for adding electric brakes. Electric brakes with a complete breakaway kit are an available configuration. Confirm the equipment installed on the specific trailer before towing. Can I haul an ATV or side-by-side on it? Yes, provided the equipment fits the 77″ deck and the combined weight of the equipment and cargo remains within the trailer’s rated capacity. Big Tex specifically identifies the rear ramp gate as useful for golf carts, ATVs and side-by-sides. What size ball does the 35SA-12 use? The standard coupler is a 2″ A-frame coupler. Verify the coupler installed on the actual trailer before towing. Safety & Cargo Securement Before loading, confirm that the combined weight of your cargo and equipment remains within the trailer’s rated capacity and that your tow vehicle is properly rated for the loaded trailer. Distribute cargo appropriately, secure every load with properly rated tie-down equipment, and inspect the tires, coupler, safety chains, brakes and lights before every trip. To cross-verify that your trailer configuration conforms to modern cargo security standards, review the safety regulations listed on the NATM Website.
