Tilling Depths

WAHNING: Before

tilling, contact your telephone or utilities company and inquire if undergroundequipment or lines are usedon your property. Do not till near buriedelectric cables,

telephone lines, pipes or hoses.

This is a CRT(counter-rotatingtine) tiller. As the wheelspullforward, the tinesrotateback- ward. Thiscreatesan "uppercut" tine actionwhich digs deeply,uprooting soil and weeds. Don'toverloadthe engine,but dig as deeplyas possibleon eachpass. Onlater passes,the wheelsmaytendto spinin thesoft dirt. Helpthemalongby lifting upslightly onthehandlebar (onehand,palm up,works most easily).

Avoidthe temptationto pushdown on the handlebarsinan attemptto force thetiller to dig deeper.Doingso takesthe weightoff the poweredwheels,causingthemto lose traction. Withoutthe wheelsto holdthe tiller back,the tineswill attemptto propelthe tiller backward, towardsthe operator.(Sometimes,slightdownwardpressureonthe handlebarswill helpget througha particularlytough sectionof sod or unbrokenground, but in most casesthiswon't benecessary.)

•Whencultivating(breakingup surfacesoil aroundplantsto destroyweeds,seeFig.4-9), ajust the tinesto dig only 1"to 2" deep.Using shallowtilling depthshelps preventinjury to plantswhoseroots often grow close to the surface. If needed,lift up on the handlebars slightly to preventthetinesfrom diggingtoo deeply.(Cultivatingona regularbasisnot only eliminatesweeds,it alsoloosensandaerates thesoil for bettermoistureabsorptionandfaster plantgrowth.)

ChoosingCorrectWheel & Tine Speeds With experience,you will find the "just right" tilling depth andtilling speedcombination that is bestfor your garden.

Selectionof the correct enginespeed,in relationto the tilling depth,will ensurea sufficientpower levelto do the jobwithout causingthe engineto labor.

Whiletilling, relaxandletthe wheelspullthe tiller along while the tines do the digging. Walkon the side that is not yet finished(to avoid makingfootprints in the freshly tilled soil) and lightly, but securelygrip the han- dlebarwith just onehand.

Wheneverpossible, walk on the untilled sideof the unit to avoid makingfootprints in your freshly tilled or cultivated soil. Foot- prints causesoil compactionthat can ham- per root penetrationand contribute to soil erosion. They can also "plant" unwanted weed seeds back into the freshly tilled ground.

Tilling wet soil often results in large,hard clumps of soil that can interferewith plant- ing. If time permits,wait a day or two after heavyrains to allow the soil to dry before tilling. Testsoil by squeezingit into a ball. If it compressestoo easily,it is too wet to till.

Preparing Seedbeds

•Whenpreparingaseedbed,go overthe samepathtwice inthefirst row,then over- lapone-halfthetiller width onthe rest of the passes(seeFig. 6). Whenfinishedin onedirection,makea secondpassat a right angle,as shownin Fig.4-7. Overlap eachpassfor best results (invery hardground, it maytakethree or four passesto
