The Husqvarna family of brands use a variety of transmission brands and various models with in those brands in our products including TuffTorq. When equipment is designed The various OEMs (engine and transmission builders) must also approve the design. When you weigh the tractor at the wheels the weight is divided between the wheels so the full weight of the tractor is not on the rear axle, with the greatest weight from the engine over the front wheels. The weight of the rear end is less than 200 pounds on the typical tractor, so then when you add the operator and collection system you are well with in the weight limits of the transmissions.
