A disassembly tool for a knock-on sweep assembly of an implement including a friction mount for securing a sweep in a mounted position on a sweep support, the sweep having an attaching portion with an upper edge, a forward soil engaging portion, a retainer engaging the attaching portion and having a locking position to prevent the sweep from dislodging from the sweep support, the retainer movable from the locking position to a release position for removing the sweep, the disassembly tool comprising:

• a handle having an engaging end, the engaging end including a downwardly directed contact surfaces for engaging the upper edge;
• an impact receiving member for facilitating driving of the contact surfaces in a sweep removal direction to dislodge the sweep from the friction mount;
• a retainer contacting projection offset vertically from the downwardly directed contact surfaces for moving the retainer to the release position as the sweep is dislodged;
• wherein the retainer contacting projection includes a retainer guide portion for positioning the retainer relative to the ears and preventing damage to the retainer as the sweep is dislodged;
• and
• wherein the engaging end includes a surface contacting the sweep as the retainer is moved into the release position to prevent damage of the retainer by impact forces during dislodging of the sweep.
