Removing End Caps Transport Position The end cap , which are used to avoid tilled soil from overflowing onto unwanted areas , are removable from Depth Stake the outer axle . Remove the hairpin clip and clevis pin that is securing each end cap and slide end cap off the axle . See Figure 8 . Shallow Tilling Wheel Setting For Deep Tilling Deep Tilling End Cap Figure 10 By increasing the depth of the depth stake , the forward speed of the machine is reduced and the working depth is increased . When the depth stake is raised , the Clevis Pin Hairpin Clip working depth of the machine is reduced and the forward speed is increased . The working depth of the Figure 8 machine may be predetermined by setting the depth stake and wheels so that the wheels are about four Controlling Speed And Tilling Depth inches from the ground when the tines and depth stake are resting on the ground . This setting will permit a Wheel Yoke Adjustment working depth of about four inches . When presetting Place wheel yoke so that the wheels are forward the working depth , the handles should be adjusted so ( nearest point between wheels and tines ) for shallow the hand grips are a little above waist . The tiller will be tilling , cultivating and transport . The forward speed will lower when the tines and depth stake penetrate the increase . Turn yoke around ( farthest point between ground . wheels and tines ) for deep tilling . Forward speed will decrease . See Figure 9 . Figure 11 When tilling , leave approximately 8 inches of untilled Position Wheel Yoke Position Wheel Yoke For Shallow Tilling For Deep Tilling soil between the first and second tilling paths , then make the third path between the first and second . In Figure 9 some soils , the desired depth is obtained the first time over the garden . In other soils , the desired depth is Depth Stake Adjustment obtained by going over the garden two or three times . In The depth stake acts as a brake for the tiller and the latter case , the depth stake should be lowered controls the depth and speed at which the machine will before each succeeding pass over the garden . Passes operate . Remove the clevis pin and hairpin clip to raise should be made across the length and width of the or lower depth stake . See Figure 7 . garden alternately .

passes across its width . The addition of decayed Handle Pressure organic matter will substantially increase the fertility of Further control of tilling depth and travel speed can be your garden . For proper decaying action , fertilizer obtained by variation of pressure on the handles . should be applied and worked in with the mulch • A downward pressure on the handles will reduce materials . Breaking up leaves and straw and mixing it the working depth and increase the forward speed . with several inches of soil causes the soil to hold • An upward pressure on the handles will increase moisture longer and allows proper aeration of the plant the working depth and reduce the forward speed . root system . This also retards the growth of weeds . The type of soil and working conditions will determine the actual setting of the depth stake and the handle pressure required . Throttle Control The throttle control lever adjusts the engine speed and stops the engine . With the throttle control lever pushed completely forward , the carburetor is in START position . Pulling the throttle control back slightly adjusts the engine speed to FAST . Pulling the throttle back further reduces the engine speed to SLOW . Pull the throttle completely back to stop the engine . Use maximum engine speed for deep tilling . Move the throttle control to SLOW when transporting the tiller . Figure 12 Transporting The Tiller To transport the tiller to or from the garden , pivot the depth stake forward , out of the way . See Figure 10 . With the throttle control in SLOW position , the unit will walk freely on top of the lawn . If the operator does not allow the tiller to move freely , the unit will start to till the surface . Cultivating For cultivating , a two to three inch depth is desirable . Setting the wheels and depth stake so that the wheels are about two inches above the ground while the tiller is resting on the tines and depth stake will allow the machine to work at cultivating depth . The throttle should be set to control forward movement to a slow walking speed . With the outer tines installed , the working width of the machine is 22 or 24 inches . For cultivation , this may be reduced to 13 inches by removing the outer tines . Refer to the Adjustment Section . When laying out plant rows , be sure to allow enough width to permit cultivation between the rows . In growing corn or similar crops , check - row planting will permit cross cultivation and practically eliminate hand hoeing . See Figure 12 . The tiller has many uses other than tilling and cultivating a garden . One of these is the preparation of lawn area for seeding . The tiller will prepare a deep seed bed which will be free of hard untilled spots , allowing a better stand of grass to grow . The tiller is very useful for loosening hard soil for excavation with a shovel . No tedious handwork will be necessary . Your tiller may be used for mixing compost in the pile , or for mixing it with the soil in your garden . This should be done after the soil has been broken to the full working depth . The compost should be worked in to a depth of six to seven inches . This may be done by working the length of the garden and then by making separate 10

SECTION 5 : MAKING ADJUSTMENTS WARNING : Disconnect the spark plug wire and ground it against the engine before performing any adjustments . Engine Adjustment Refer to the separate engine manual for engine adjustment instructions . 22 ” Wheel Adjustments To adjust the wheel yoke and wheel position , refer to the Operating Section . Clutch Control Adjustments To adjust the clutch controls , refer to the Final Adjustment section of assembly instructions . 24 ” Depth Stake Adjustment To adjust the depth stake , refer to the Operating Section . Tine Width Adjustment The tilling width of the unit is 22 inches . Tilling width can 13 ” be increased to 24 inches by removing the clevis pins and hairpin clips , sliding the outer tines out one inch , Figure 13 and securing in this position with the clevis pins and hairpin clips . For cultivation , reduce the tine width to 13 inches by removing the outer tines completely . See Figure 13 . SECTION 6 : MAINTAINING YOUR TILLER WARNING : Disconnect the spark plug wire The spark plug should be cleaned and the gap reset and ground it against the engine before every 25 hours of engine operation . Spark plug performing any repairs or maintenance . replacement is recommended at the start of each tiller season ; check engine manual for correct plug type and gap specification . Engine Clean the engine regularly with a cloth or brush . Keep Refer to the separate engine manual for engine the cooling system ( blower housing area ) clean to maintenance instructions . permit proper air circulation which is essential to engine Maintain engine oil as instructed in the separate performance and life .
