The only tool you will need is a 3/4" wrench (minimum 12" long for good leverage). There are two optional accessories that make the following steps easier. The Kickstand accessory prevents the PTO Power Unit (engine end) from falling forward 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 hole when 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 place it in the Tine Cradle or prop it up to prevent the attachment from falling forward. when an attachment is removed (Photo 4-37). The Tine Attachment Cradle accessory gives you a handy support in which to rest the tine attachment when it is removed from the tiller (see Photo 4-38). For more information about other accessories, refer to “Accessories” at the back of this Manual. Photo 4-37: The Kickstand accessory prevents engine from tipping. Photo 4-38: The Tine Attachment Cradle accessory is a handy option. To Remove Tine Attachment: 1. First be sure the engine is stopped, the electric start key is removed, and the spark plug wire is disconnected. 2. Place tiller on level ground. 3. Place the Wheels/Tmes/PTO Drive Lever in NEUTRAL (refer to Photo 4-39).

Forward Interlock Levers Wheels/Tines/ PTO Drive Lever Tines/PTO Clutch Lever 4. Place Tines/PTO Clutch Lever in DISENGAGE (Photo 4-39). 5. Place Wheel Speed Lever in FREE WHEEL (Photo 4-39). 6. Place a strong support under the engine or use the Kickstand accessory (if so equipped) to prevent the engine from tipping forward when the tine attachment is removed. See Photo 4-40. Photo 4-40: Block up engine. 7. With a 3/4" wrench, loosen the two swing-out bolts that connect the power unit transmission to the tine attachment and swing the bolts outward. See Photo 4-41. Hint: an extra-long wrench for leverage is very helpful. 8. Use one hand on the handlebars to tip the power unit forward about one inch while pulling the tine attachment backward. The guide pin on the power unit will release from the guide hole in the tine attachment. See Photos 4-42 and 4-43. Wheel Speed Lever Photo 4-41: Move both of the swing-bolts outward. Note - Store tine attachment at level position to avoid gear oil leakage around dipstick. 9. Place the dust cap (comes with certain attachments; plastic wrapping will substitute) over the “dog” clutch coupling of the tine attachment to keep it clean. 10. The power unit is now ready to accept any other powered or non-powered attachment. See that attachment’s Owner/Operator Manual for installation and operation instructions. To Replace Tine Attachment: 1. Follow Steps 1-through 5 of the previous tine attachment removal instructions. 2. Move the two swing-out bolts on the power unit to their outward position (slide the washers next to the bolt heads too). 3. Slowly roll the power unit back to the tine attachment. Move the Kickstand down (or support the engine with a wood block). 4. Remove the dust cap (or protective wrapping) from the clutch coupling on the tine attachment. 5. Carefully align the alignment pin on the power unit with the alignment hole in the tine attachment and bring the two units together (see Photo 4-43). Photo 4-42: Lift handlebars while pulling attachment away from power unit. Photo 4-43: Align the guide pin with the mounting hole. 41 Operation 6. Move the two swing-bolts into the slots of the tine attachment. Alternately tighten each bolt until they are tight enough to make the concave washers on the bolts flat. The bolts must be very tight - if you have a torque wrench, tighten each one to between 70-80ft.-lbs. See Photo 4-44. IMPORTANT - The swing-bolts must be kept very tight to prevent damaging wear to the ‘dog’ clutch couplings, alignment pin or the alignment hole. Check bolt tightness every 2-A operating hours. 7. Remove the engine support before moving the tiller in a forward direction. Photo 4-44: Tighten both swing-bolts very securely with a long 3/4" wrench. Tighten them to between 70-to-80 ft. lbs.
