Big Windrower Rakes Rocks Fast
Smyth Welding makes clearing stones from fields fast with their Folding Stone Windrower. The 28-ft. rake sweeps up to 12-in. dia. rocks (longer if odd shape) into a 5-ft. wide windrow.
    “We built it rugged enough that you can add an optional rear hitch to pull a hydraulic stone picker behind it,” says Barry Smyth, Smyth Welding and Machine Shop. “We use teeth with hardened caps, but only 5/8 in. thick to move the least dirt possible.”
    Each wing of the windrower consists of a 24-in. dia., double spiral drum with the narrow teeth. As it rolls across the field, it moves stones, not dirt, without excessive soil compaction. Hydraulic depth wheels with manual depth stops let the operator select working depth based on field conditions and soil types.
    Single remote hydraulics are all that are needed for raising and lowering the wings. This allows the addition of hydraulic extensions with rear couplers for use with a hydraulic stone picker.
    “The ability to pull a stone picker behind the windrower is a very popular option,” says Smyth.
    The windrower comes with either a pto or hydraulic drive. An enclosed chain case at the end of each wing provides drive to the drums.
    The hydraulic drive requires 25 gpm at 2,500 psi. A minimum 65 hp. tractor is suggested for the pto drive. However, Smyth recommends using at least a 100 hp. tractor to ensure sufficient traction to handle hills.
    The Folding Stone Windrower starts at $29,000 (Canadian). It comes road ready with transport lights and safety chains.
    The company also makes a 32-ft. floating section stone windrower and a 12-ft. tow- behind stone windrower.
