Our lawn and garden wagons and trailers that are designed to accept the model 3010 hand-operated dump system are designed for a 45 degree maximum dump angle. The lawn tractors that these wagons and trailers are designed for lack the weight to operate safely at any higher dump angle. 2,000-2,500 pounds 7 ft in the air can tip easily on uneven ground. Most real world applications of these wagons and trailers are: firewood, brush, mulch, tools, garden & yard debris, and heavier per cubic foot items such as stone and soil and work very well for these applications. However, if your main use for a dumping wagon or trailer is going to be large loads of sand, gravel, or soil, we might suggest our 2 ton units with a tractor-operated hydraulic cylinder like the Model 8300 shown at the bottom of the page.
