HD cast iron closing wheel upgrade for SAYA PT-755 and PT-907 models. Replaces standard closing wheels with heavy-duty cast iron for superior seed-to-soil contact and long-term durability.
Compare with Other DrillsThe HD Cast Closing Wheel upgrade kit for the larger SAYA PT-755 and PT-907 models. Same heavy-duty cast iron construction and superior seed-to-soil contact as the CR05 kit, sized for the wider-frame drills. If you're running a 907 for native grass work, this upgrade is especially valuable — cast iron closing wheels handle the firming pressure needed for tiny native seeds much better than standard rubber wheels.
