VERY IMPORTANT

Before operating your PTO Power Unit for the first time, make sure that you have:

•Read all the safety instructions in Section 1 of this Manual and in the Manual supplied with any attach- ment.

•Read the controls information and operating procedures for the tiller and engine described in Sections 3 and 4 of this Manual and in the Engine Owner’s Manual.

•Read and understand the assembly instructions, controls informa- tion, and operating procedures for the attachment as described in the Attachment Owner’s Manual supplied with the attachment.

The following steps explain how to remove and replace the tine attachment. You will need a 3/4" wrench (minimum 12" long for leverage).

Removing Tine Attachment

1. Move the tiller to level ground.

2. Be sure the engine is stopped, the electric start key is removed, and the spark plug wire is disconnected and moved away from spark plug.

CAUTION

TO AVOID PERSONAL INJURY OR DAMAGE TO EQUIPMENT:

•Stop the engine, remove the electric start key, disconnect the spark plug wire and let the engine and muffler cool before removing or installing any attachment.

•Do not place hands, tools, or any object near or inside the PTO access area while the engine is running.

•When removing or replacing the tine attachment, be careful of the sharp edges on the tiller hood. Wear thick gloves for hand protection.

•When the tine attachment is removed, always prop it up with a block to prevent the attachment from falling forward.

3. Place a sturdy support under the engine to prevent the engine from tipping forward when the tine attachment is removed (Figure 4-23).

4.Place the Wheels/Tines/PTO Drive Lever into NEUTRAL (Figure 4-22).

5. Place Tines/PTO Clutch Lever in DISENGAGE (Figure 4-22).

6. Place Wheel Speed Lever into FREE WHEEL (Figure 4-22).

Figure 4-23: Block up engine.

7.Loosen the two swing-out bolts (Figure 4-24) that connect the power unit transmission to the tine attachment and swing out the bolts (Figure 4-25).

HINT: Loosening swing-out bolts can be difficult. Use an extra-long wrench for leverage.

8.Tip the PTO power unit forward about one inch with one hand while pulling the tine attachment back (Figure 4-26). The guide pin on the power unit will slide out of the guide hole in the tine attachment (Figure 4-27).
