I bought these yesterday, installed one on my Woods RC4 behind my John Deere 1025R. Spent the day mowing a two acre field that was overgrown with dense tall weeds and grooming three miles of logging trails. Everything worked great. Other users have mentioned bolts shearing when they engage their rotary cutter. I wonder what RPM they engaged their cutter. The correct way is with the tractor rpm’s around 1500-1700, engage the PTO then slowly and steadily increase the PTO to 540. It is important to stay within the scope of what your cutter is designed to do. If you’re trying to cut 2” branches all day and your cutter isn’t designed for that.... the shear bolt will protect you and your wallet from yourself by shearing.

These are absolute garbage, went through an entire package in less than an hour trying to cut a field that is cut every couple months, only difference was using a brand new Woods cutter. First two broke on initial engagement of PTO, at min RPM, other three broke randomly while cutting field, nothing heavier or thicker than any other spot, no dirt pile/ ant pile, no large sticks or logs, no rocks, just very cheap junk!
