OPERATION You will find tilling much easier if you leave a row untilled BREAKING IN YOUR TILLER between passes . Then go back between tilled rows . Break - in your belts , pulleys and tine control before you ( See Fig . 9 ) There are two reasons for doing this . First , actually begin tilling . wide turns are much easier to negotiate than about - â¢ Start engine , tip tines off ground by pressing handles faces . Second , the tiller won't be pulling itself , and you , down and engage line control to start tine rotation . Allow toward the row next to it . tines to rotate for five minutes . Set depth stake and wheel height for shallow tilling when Check tine operation and adjust if necessary . See working extremely hard soil or sod . Then work across " TINE OPERATION CHECK " in the Service and Adjust - the first cuts at normal depth . ments section of this manual . TILLING HINTS handling your tiller , start actual field use with throttle in slow position ( mid - wayto I _ CAUTION : Until you are accustomed between " FAST " and " IDLE " ) . To help tiller move forward , liftup the handles slightly ( thus lifting depth stake out of ground ) . To slow down the tiller , press down on handles . If you are straining or tiller is shaking , the wheels and depth stake are not set properly in the soil being tilled . The proper FIG . 9 setting of the wheels and depth stake is through trial and error and depends upon the soil condition .

Tines will not readily penetrate dry , hard soil which may contribute to excessive bounce and difficult handling of your tiller . Hard soil should be moistened before tilling ; however , extremely wet soil will " ball - up " or clump during tilling . A Wait until the soil is less wet in order to achieve the best results . When tilling in the fall , remove vines and long grass to prevent them from wrapping around the tine shaft and slowing your tilling operation . FIG . 10 9
