Bushing for Nobili Frontoni Vigolo Ferri Agrimaster mulching knives The bushing for mulcher knives is made of steel produced in Italy, and is necessary to keep the blades on the rotor of the Nobili Frontoni Vigolo Ferri Agrimaster shredders in a vertical position. The spacer bushes must be inserted on the rotor attachments before the knives, so that they are at the right distance to rotate on the support while always remaining in a vertical position. In this way the bushing allows the shredder knives to work in the best way and above all always in balance, avoiding damage to the equipment and guaranteeing optimal chopping. The AL56324 spacer bush is applicable to the AL55310 mulcher knives.
