The slot should measure approximately 4-3/8". There are two weld pins on the front of the tiller. Push the tiller forward, then to the left so the weld pins go through the bottom hole in the pivot support brackets. See figures 10 and 11. Secure the weld pin on the right hand side of tiller using spacer (Q) and hairpin cotter (J). See figure 10. FIGURE 10 6 23. Secure the weld pin on the left hand side of tiller using one flat washer (D) and hairpin cotter (J). See figure 11. FIGURE 11 24. Move the lift lever on the tractor to the second notch on the index bracket as shown in figure 12. 25. Place a board under the tines. Thread the assembly until it lines up with the bottom hole in the lift handle. Secure ferrule to lift handle using flat washer (C) and hairpin cotter (J). See figure 12. NOTE Refer to operation section for additional adjustment information. FIGURE 12 26. Hook the short end of extension spring (A) to the idler bracket support arm on the left side of unit. Hook the longer end of spring to the hex bolt on support pivot bracket which was assembled in step 7. See figure 13. 7 I DRIVE PULLEY 27. FIGURE 14 Assemble the belt as follows (refer to figure 14). A. Belt is attached to the idler pulley assembly. Back of the belt (flat side) goes against the idler pulley. B. Slip belt up and over pulley on tiller ("V" side of belt goes against the pulley). C. Twist the belt 90° to the right as shown in figure 14. Slip the belt around the drive pulley on the tractor. NOTE The tines on the tiller are designed to rotate in the opposite of the wheels on the tractor. If they rotate in same direction as the wheels, the belt is twisted in the wrong direction. Unhook the belt from the drive pulley and twist in the opposite direction. If there are holes provided in the tractor frame, hook the lift links up out of the way using the four extension springs (K). See figure 15. FIGURE 15 8 OPERATION ADJUSTMENT FERRULE CONTROLS Lever . he lift lever which is used to raise and lower the tiller and provide tilling depth adjustment is located on the right hand side of the tractor. To raise the tiller, pull back on the lift lever. To transport the tiller, place lift lever in the highest position. PT.O. Lever The P.T.O. lever is located on the right hand side of the tractor. The tines are engaged by lifting the PT.O. lever to the "Engaged" position. Lower the RT.O. lever to the "Disengaged" position to stop the tine rotation. HOW TO USE YOUR TILLER When tilling sod or soil which has not been tilled before, select a shallow tilling depth with the lift lever, and use a slow ground speed. For further depth, lower the lift lever and make several more passes over the area, each time tilling at right angles to the previous pass. See figure 16. hen tilling loose soil, use a higher ground speed. se the highest ground speed for pulverizing the soil or for transporting the tiller. For best results, always till the ground at least twice (lengthwise, then widthwise) as shown in figure 16. FIGURE 16 The adjustment ferrule oh the lift rod assembly provides additional tilling depth adjustment. Recommended adjustment is as follows. 1. Place lift lever in second position. 2. Place a board under the tines and adjust the ferrule to fit into lift lever. This adjustment provides approximately 3" ground clearance with the lift lever in the highest position (for transport). Move the ferrule further back on the rod to reduce the tilling depth. MAINTENANCE CHAIN CASE LUBRICATION The chain case is sealed at the factory and does not require checking or changing. If the chain case is disassembled for repair, replace the grease with 20 ounces of plastilube "0" grade grease (part number 737-0133, 14 ounce container). BEARING CUP At least once a season, remove the bearing cup on the right hand side of tiller housing. See figure 17. Clean and refill with 2 ounces of plastilube "0" grade grease (part number 737-0133). FIGURE 17 LIMITED TORQUE PULLEY If the limited torque clutch is disassembled for any reason, reassemble as shown in page 14. Using a torque wrench, tighten the first hex jam nut to 350 in. lbs., then lock it in place with the second hex jam nut. 9 S3 ION Model 746 and 19746 LAWN TRACTOR FRAME ENGINE PULLEY PARTS LIST FOR MODEL 746 28" TILLER ATTACHMENT REF.
