BLADE BLOCKER "rider" instructions. Generation 2, post spring '05
IMPORTANT: read completely before installation.

BLADE BLOCKER is designed to operate in conjunction with the discharge deflector shield on your mower. BLADE BLOCKER is not intended to be used as a mulching plate or in place of the discharge shield. Its purpose is to temporally block the discharge opening in order to prevent large volumes of grass clippings from being discharged onto areas where they are not desired.

Begin by identifying all parts. Study fig # 6 as a general installation guide. Carefully note placement of all components. NOTE: Before drilling any holes in mower or any of the BLADE BLOCKER parts be certain of the mounting locations. Clamp and/or hold all assembled parts in place and operate the baffle before final installation. Make certain the installation does not interfere in any way with moving parts such as; blades, controls, switches, steering controls (including the handles in the pivoted "out" position), belts, tires, safety equipment, etc. The vertical post and linkage must be mounted in a position rearward enough so that when the discharge shield is raised it will clear the post and linkage. Cut discharge baffle to fit discharge opening on mower. In most installations the baffle should be cut oversize so that it comes in contact with the edges of the opening to stop the baffle when lowered. The baffle can be cut with a carpenters hand saw or hack saw. It may be desirable to round the bottom corners to help prevent the baffle from hanging up. Attach baffle to deck using hinge with four 5/16" bolts and lock nuts. The extended hinge pin with tab must face towards the rear. It might be necessary to cut a small notch in the corner of the discharge shield for the actuator arm to pass through when the shield is lowered. Do not make the notch any larger than needed for the shield to be lowered and the actuator arm to rotate. See fig # 5. Attach mower deck bracket to mower deck using two 3/8" bolts and lock nuts. On most mowers the bracket will need to be attached towards the rear of the deck. The mower deck bracket is slotted to provide mounting versatility. Both bolts can be used in a single slot if required. Assemble vertical post and linkage assembly as shown in figs # 1 and 3. Attach handle to vertical post using the hole closest to the straight end of the handle with a 3/8" x 1&1/4" bolt and lock nut (the handle can be attached to either side of the post and face either direction for the best ergonomics) Install a socket head bolts and lock nuts into the post on the same side as the handle. The heads of the bolts will act as stops for the handle. Insert vertical post into mower deck bracket. After determining the proper position for the vertical post by turning it in the mower deck bracket, drill a 5/16" hole through the mower deck bracket and post. There is a pre drilled hole in the angle part of the bracket to act as a guide for drilling. Secure post to bracket using a 5/16" by 2" bolt and lock nut. Once installation is complete the baffle must be adjusted so that it does not interfere with the discharge chute. This is accomplished by adjusting the turnbuckle. With the handle and baffle in the raised position and the discharge chute in the lowered position rotate turnbuckle to raise or lower baffle to a position flush (parallel with) the discharge chute without raising chute. See fig # 4. When the baffle is closed it will block discharge opening. See fig # 2. Tighten all jam nuts on the control linkage after adjustment.
