    Note: Position the flat portion of the switch toward the operator.

Parts needed for this procedure:

Note: The machine must be equipped with the Auxiliary Power Unit Kit, Toro part no. 30382.

1. Cover exposed connectors on the wiring harness with masking tape or electrical tape to keep debris out of the connectors while routing the harness.

2. Route and connect the wiring harness (Figure 30 and Figure 31) at the follows locations:

   • Hydraulic-manifold connectors

   • Relays (6) on the relay bracket

   • Main harness connector, located under the right operator controls by the standard control module

     Note: The main harness connector is a 2-wire Metri-pak connector (brown and tan wires)

   • Deck lift in A and B

     Note: Unplug the 2 connectors from the lift-manifold block and plug them into the wiring harness.

   • Deck lift out A and B

     Note: Plug the wiring harness into the lift-block manifold where you just unplugged the 2 connectors.

   • Pink power-wire connector

   • Ground to the ground block

   • Lift/lower switch

   • Float/enable switch

3. Secure the wiring harness to the machine with cable ties.

   Important: Keep the harness away from all hot, sharp, or moving parts.

   Important: Secure the wiring harness away from the tail pipe of the machine.

1. Grease all the new grease fittings with Number 2 lithium-based grease.

2. Check the hydraulic fluid level and replenish as required.

3. Connect the negative (–) battery cable.

4. Start the machine and operate the rear lift. Check for leaks and replenish hydraulic fluid as necessary.

   Note: If installed correctly, the manifold should have no electrical power when the key is in the OFF position.

Move the switch to the LIFT position to raise the attachment and to the LOWER position to lower the attachment (Figure 33).

Moving the switch to the FLOAT position allows the attachment to follow the contour of the ground. Moving the switch to the POWER DOWN position adds weight from the machine to increase ground engagement force (Figure 33). Higher ground engagement force decreases the traction capacity of the machine.

2. LIFT/LOWER switch

To increase or decrease the engagement angle of the attachment, proceed as follows:

1. Loosen the jam nuts on the threaded link (Figure 34).

2. Rotate the hex tube until you achieve the desired angle (Figure 34).

3. Tighten the jam nut to lock the adjustment (Figure 34).

4. With the engine operating at low idle, raise the rear attachment to make sure that it does not contact the hood.

Use the following weight charts to determine the correct amount of front weight required for your machine.

Use the following weight charts to determine the correct amount of front weight required for your machine.

• Read and understand the attachment Operator's Manual before using the machine.

• Make sure that the appropriate weight mount bracket and front weight(s) are installed for the rear attachment.

• Remove rear attachment and any loose front-end weights prior to mowing.

• Use care when operating the machine when a rear attachment is installed, because it is wider than the machine and may contact poles, fences, or trees.

• Never operate the machine near bystanders.

• Lubricate the grease fittings with Number 2 lithium-based grease weekly or after every washing.

• When operating in dusty conditions, the air cleaner should be checked daily. A safety air-cleaner element is available and may be added to the existing air cleaner for additional engine protection.
