I bought this spreader a year ago. We have 2 horses on a 1.5 acre pasture. We want to keep it green and maximize grazing area so manure management is critical. We collect manure daily, compost it, and spread compost about every 4 months. The 25 has been great. It spreads the composted manure evenly and efficiently. The ground drive works perfectly. This spreader is well worth the money.
