All I know she'll hold about 2.5-3t. chains tend to wrap themselves. We did put new bolts on the chains this year, starting to rub against the metal. Dad had it since the 80s and was bought 2nd hand. Surprisingly still here. Again would love a rd spreader. Even them k two 6t spreaders be the jobSteady will do it, is it a 6 cubic yard spreader? The secret with a barrel spreader is have a full set of chains and flails, also the end flails need to be complete and dont fully fill the ends to allow it to start. Also wrapping the chains using the PTO brake helps for an easy start.
