Tilling Procedure When tilling , leave approximately eight inches of untilled soil between the first and second tilling paths , then make 4 the third path between the first and second , Figure 4 â 7 . In some soils , the desired depth is obtained the first 4 5 2 3 1 time over the garden . In other soils , the desired depth Operating is obtained by going over the garden two or three times . Passes should be made across the length and width of Your Tiller the garden alternately . Rocks which are turned up should be removed from the garden area . Figure 4 â 7 : Recommended tiller paths . With the outer tines installed , the working width of the machine is 24 inches . This width may be expanded to 26 inches by removing the clevis and cotter pins , sliding each outer tine outward away from the center of the unit and resecuring the pins in the holes provided . See Figure 4 â 8 . WARNING Removing End Caps The end cap , which is used to avoid tilled soil from Be sure no one other overflowing onto unwanted areas , are removable from the than the operator is axle .

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 Refer to the engine garden . This should be done after the soil has been manual for detailed broken to the full working depth . The compost should be instructions pertaining worked in to a depth of six to seven inches . This may be to engine controls . done by working the length of the garden and then by making separate passes across its width . The addition of decayed organic matter will substantially increase the fertility of your garden .
