When soil conditions are severe and several passes must be made over a certain area, the depth bar sotting should be lowered each time a pass is made. Further control of tilling depth and travel speed can be obtained by variation of pressure on the handle or the throttle setting. A downward pressure on the handles will increase the working depth and reduce the forward speed. An upward pressure on the handles will reduce the working depth and increase the forward speed. The type of soil and working conditions will determine the actual setting of the depth bar and the handle pressure required. NOTE If the tines tend to bounce instead of cutting into the soil, one or more sets of tines may be on backwards. The cutting edge of the tines should enter the soil first. 1. Tine engagement and forward travel is achieved by moving the clutch control lever to FORWARD position. Tine rotation and forward motion are stopped by moving the clutch control handle to NEUTRAL position. Reverse tine action and reverse travel motion can be maintained by HOLDING the clutch control handle in REVERSE position. Releasing the handle stops reverse operation automatically. 2; The throttle control lever adjusts the engine speed. It also gives finger tip control of the carburetor and magneto stop switch. With the throttle control knob pushed completely forward, the carburetor is in START position. Pulling the knob back slightly adjusts the engine speed to FAST. Pulling- the knob back further reduces the engine speed to SLOW. When the knob is pulled completely back, the magneto stop switch grounds out the spark and stops the engine. 3. With the depth bar positioned out of ground engagement position, self propelled transporting of the tiller is easily achieved. With no pressure on the handles and the throttle control set for SLOW engine speed, move the clutch control handle to the FORWARD position and let the tiller gently propel itself. ADJUSTMENTS Belts. Belt slack is taken up by a spring loaded idler pulley. Because of this, belt adjustment is not required. Clutch. No adjustment of the lower clutch rod is required. This is done automatically by the spring loaded idler. NOTE Belt and clutch adjustments can be made with the adjustable control rod. Throttle. If adjustment becomes necessary, the throttle control wire assembly can be reset as follows: 1. Loosen, but do not remove, screw securing throttle control wire assembly at engine. 2. Move throttle control knob to STOP position. 3. Move lever, to which control wire is fastened at engine, to STOP position and retighten screw to secure throttle control wire assembly. Tines. The standard width of cut is 26". Because of the various types of work the tiller may be put to, variation in the tilling widths may be necessary. This can be accomplished in a number of ways. 1. Standard tine arrangement________________26" 2. Remove both outer tine assemblies--------12" 3. Remove tines that point outward from outer tine assemblies. Tines may be interchanged with opposite sides ____________________ 20" 4. Add tine extensions to standard arrangement __ 4.0" NOTE When adjusting tines, be sure the cutting edges enter the soil first. MAINTENANCE AND LUBRICATION Engine. Service engine in accordance with the engine manufacturer's owner's guide. NOTE To drain oil remove oil filler plug and tip tiller on its side. Drain oil while the engine is warm. See engine manual for filling instructions. Throttle. Periodically lubricate throttle control lever and throttle control wire assembly with a few drops of light oil (SAE 10 or 20) for ease of operation. 6 Gear Case. Proper lubricant level shouid be up to the front pipe plug. Check with tiller on a level surface. Add lubricant through vented pipe plug hole. Add enough to bring level up to front pipe plug hole. Use Mobilube SAE 140 gear oil or equivalent. Gear case should be maintained with five (5) ounces of lubricant. TILLER GEAR CASE BEARING ADJUSTMENT CAP (Small) If the bearing adjustment cap on the worm shaft is over-tightened the bearings on the worm shaft can seize during operation. The cap should protrude approximately 1 /32" to 1/16" from the gear case. REPLACING TILLER GEAR CASE OIL SEALS 1. Drain lubricant. 2. Remove tine assemblies. 3. Remove bearing cap. (See reference 24, pages 10 and 11.) 4. Remove bearings, worm wheel and tine shaft. Do not remove bearing races'. 5. Remove oil seals from gear case and bearing cap. 6. Remove all burrs from holes in tine shaft. 7. Dip oil seals in lubricant and then insert one in gear case and one in bearing cap. 8. Wipe tine shaft clean of filings and lubricate before assembling with bearings and worm wheel in gear case. Insert shaft slowly to prevent seals from catching in holes in shaft. 9. Replace bearing cap. CAUTION Do not damage oil seals. The open flanges face to the outside of the gear case. 10. Tighten bearing cap, retighten screws evenly. 11. Replace tine assemblie...
