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
passes across its width. The addition of decayed
organic matter will substantially increase the fertility of
your garden. For proper decaying action, fertilizer
should be applied and worked in with the mulch
materials. Breaking up leaves and straw and mixing it
with several inches of soil causes the soil to hold
moisture longer and allows proper aeration of the plant
root system. This also retards the growth of weeds.

TineWidthAdjustment
The tilling width of the unit is 22 inches. Tilling width can
be increased to 24 inches by removing the clevis pins
and hairpin clips, sliding the outer tines out one inch,
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.
