    MOST OFTEN ENCOUNTERED DISK BLADE FAILURES Most disk blade failures can be prevented by selecting, the correct blade size and thickness for individual conditions when buying disk. Reduction of speed areas containing rocks and stumps will greatly lengthen the blade life. Keeping gang bolts properly torqued and raising the harrow while turning will also reduce disk blade breakage.
