I realize this is a 2 wheeled tractor forum and I now own a BCS 715 2 wheeled tractor but I need some help on the weight of horse manure. I have access to free horse manure from a stable to use on my gardens. I own a single axle 6 1/2' x 12' trailer with 2' sides. That computes to 156 cubic feet of loadable space if loaded up to the 2' sides. A yard of manure is 27 cubic feet but I do not have a weight per yard for the horse manure and I realize that may vary due to moisture content and stall shavings. At 156 cubic feet of loadable space that computes to 5.78 cubic yard capacity (too much for a single axle trailer). I dropped off my trailer at the stables a week ago and hauled a load this morning with my trailer that was probably only loaded to 2/3 capacity. I only have to haul it less than 10 miles to my home but I did not think I was going to make it home. The tire were flatening out and the trailer was obviously overloaded. My single axle is rated at 3500 lbs but with a recommended load of around 2000 lbs. Does anyone know how much horse manure weighs per yard as I need to haul a lot more.
