Before starting the tractor engine, place the tiller clutch lever in the disengaged position and raise the tiller above the surface of the ground. With the tractor engine running, engage the tiller clutch and lo-rer the tiller into contact with the ground. As
the tiller works into the soil, slowly release the tractor clutch and move ahead. When coming to the end of a row, raise the tiller free of the ground before turning around.
Effective operation of the tiller will depend in a large degree upon the operator. For example, when intending to till a sod area
into a seed bed for gardening, it obviously will require several passes over the same path to break the sod and ground into fine particles suitable for a seed bed. Depending upon the nature of the soil, it will be desirable to alter the depth settings for the tiller on succeeding passes until the desired depth is reached. When tilling in soil that has been previously worked, it may be possible to
till to the desired depth from the start.
The depth of tilling is regulated by moving the stop pin in the lift lever quadrant located on the left side of the tractor. The farther the pin is moved toward
the front end of the quadrant, the deeper the tiller will work into the soil. The maximum depth for effective tilling is about 7".
Soil conditions and depth of tilling will regulate the speed with which
the tiller may be effectively operated. For average requirements, set the tractor throttle at 1/2 maximum speed and use a tractor speed slow enough to allow the tiller to work down to the desired depth. As the tiller is designed to float and follow the contours of the surface being tilled, it will be necessary to regulate the forward speed to suit the depth of tilling and the condition of the
soil being worked.
Avoid taking the tiller into wet or soggy ground.
Frequently it happens that wet soil
balls up or forms lumps that will be difficult to work up later on, o r the tine assemblies may clog with soil or clay.
In extremely hard or dry soil, it may be best to cross till; that is, till first in one direction and then till again at a 900 angle to the original direction.
