BARRELHORSE USA - 2016-03-07 1:26 PM Wood chips, manure or any organic is a no no ... it slims over an area and contains water and is slicker than owl snot ... Bring the dozer back in .. cut into a side hill and use that dirt to raise the level of the arena .... while dozer is there ... cut a big wide drainage ditch at the bottom of the side hill between it and the arena to direct any runoff away from and to keep it from flowing across the arena ... let the arena settle for several weeks .. Now ... use 2"x 12 inch wide treated boards to go around the perimeter of your arena and bring in a sand and clay mix like they use for infields on baseball fields .. and level it inside the board perimeter ......... this clay sand mix will crust over slightly when it rains and will not wash away like pure sand does .... and does not contain enough red clay to be slick ... Friends bought a road maintainer that works like magic and could be a fantastic arena leveler and you can adjust the teeth to barely loosen a couple of inches for impact control ... cost was under $1500 for the unit ... I think they bought it at J&I Industries at Madill Okla ... works like this ... so look around and find one that works on your road and arena .. without breaking the bank ... https://youtu.be/14EBqq88DD0 https://youtu.be/OIed2lzfQ-g
