Checking Tines for Wear WARNING To help avoid personal injury, stop the engine, wait for all moving parts to come to a complete stop, remove the electric start key, disconnect the spark plug wire and move the wire away from the spark plug, and let the engine and muffler cool before inspecting, removing or replacing the tines or tine holders. Inspect the tines for wear or damage after every 30 operating hours. The rate of wear depends upon hours of use and soil conditions. With use, the tines get shorter, narrower and more pointed (see Photo 5-30). If badly worn, they lose the ability to till deeply. Also, worn tines leave an ever-in-creasing “gap” in the middle of a tilled row. The normal gap is 3" between the tine tips - replace the tines when the gap widens to 5". Tines can be replaced individually or as a complete set. See replacement instructions that follow. New Photo 5-30: Check for tine wear every 30 operating hours. Figure 5-31: Replace tines when the gap between inner tines is 5" or more. (Normal gap is 3".) 54 Maintenance/Repairs B. Single Tine Replacement WARNING The tines or tine hood edges may be sharp. Wear thick gloves to protect your hands from cuts or scrapes. 1. Move the Wheels/Tines/PTO Drive Lever to NEUTRAL, the Wheel Speed Lever to either FAST or SLOW position, and the Tines/ PTO Clutch Lever to ENGAGE. 2. Gently tilt the tiller forward until the engine rests on the ground. 3. Raise the hood flap at the back of the tiller and tie it up with string. 4. Before removing a tine, note in which direction the bent tip points. The new tine must be installed in the same direction. 5. Use two 9/16" wrenches to remove the two bolts and nuts securing the tine to the tine holder plate (see Photo 5-32). Use penetrating oil on the hardware if it is rusted or hard to remove. 6. Mount the new tine exactly the way the old tine was positioned. (The sharp edge of the tine, which Photo 5-32: Removing a single tine requires taking off two bolts and two nuts. enters the soil first, must face forward when above the tine shaft.) Replace the bolts and nuts and tighten them securely. C. Removing and Replacing the Tine Holders I WARNING The tines or tine hood edges may be sharp. Wear thick gloves to protect your hands. The 16 Bolo Tines are mounted eight per side on left-side and right-side tine holders - on either Style A or Style B holders (refer to Figures 5-33A and 5-33B to see which style tine holder you have). Style “A” tine holders are secured to the tine shaft with two bolts and two nuts. Style “B” tine holders are secured with a single end bolt to the left and right sides of the tine shaft. Here’s how to replace the tines and holders as assemblies. Removal Steps: 1. Follow steps l-through-3 in “Single Tine Replacement” above. 2. Identify the tine holders as Style A or Style B, then as left-side and right-side holders - they must be replaced on the same side from which they were removed. Use a piece of chalk or a grease pencil to mark them “L” and “R.” 3. With Style A holders, remove the two bolts and nuts securing each holder (Fig. 5-33A). With Style B holders, remove the single bolt (along with the washers) from the very end of the tine shaft (Fig. 5-33B). 4. Use a soft mallet to drive the holder off the tine shaft. (Use a heavy hammer and block of wood to drive off a “frozen” tine holder.) 5. When the holder is off, clean all dirt and debris from the shaft and the holder. Apply fresh grease to the tine shaft Replacement Steps: 1. Replace the holder so the sharp tine edges face forward (toward front of tiller). Tap tine holder back on the tine shaft. 2. Grease the threads on the mounting bolt(s). Install and tighten the bolt(s) securely. ! WARNING Wear safety goggles to protect your eyes. When loosening hardware, do not hit a wrench with a metal tool— this could shatter the tool or wrench, sending metal particles into your eyes. Figure 5-33A: Style “A ” Tine Holders— Left and right-side tine holders are secured to the tine shaft with two bolts and two nuts. Figure 5-33B: Style “B” Tine Holders— Left and right-side tine holders are each secured with a single mounting bolt into the end of the tine shaft. 55 Maintenance/Repairs TINE SHAFT MAINTENANCE After every 10 operating hours, remove the left- and right-side Bolo Tine holders and clear away dirt and debris that have accumu- lated on the tine shaft or inside the tine holders. Please follow this maintenance recommendation, as debris can cause premature wear to the tine shaft and its oil seals. Refer to the previous tine holder removal instructions (see previous page). After cleaning away any debris and removing old grease from the tine shaft, apply fresh grease to the tine shaft. TIRE AND WHEEL MAINTENANCE Check tire air pressure every 30 operating hours. The recommended pressure for tilling is 10-to-20 psi (pounds per square inch). Both tires should be inflated equally. (Unequal pressure can cause the ti...
