Tilling Tips& Techniques

Let the tiller dothe work

*While tilling, relax and let the wheels pull the tiller along while the tines do the digging. Walk on the side that is not yet finished (to avoid making foot- prints in the freshly tilled soil) and lightly, but securely grip the handlebar with just one hand. SeeFigure 4-2.

oAvoid the temptation to push down on the handlebars in an attempt to force the tiller to dig deeper. Doing so takes the weight off the powered wheels, causing them to losetraction. Without the wheels helping to hold the tiller back,the tines will attempt to propel the tiller backward toward the operator- often causingthe tiller to skip rapidly across the ground.

Avoidtilling soggy,wet soil

Tilling wet soil often results in large, hardclumps of soil that can interfere with planting. If time permits, wait a day or two after heavyrains to allow the soil to dry before tilling. Test soil by squeezing it into a ball. If it compresses too easily, it is too wet to till.

Avoidmakingfootprints

Wheneverpossible, walk on the untilled side of the unit to avoid makingfoot- prints inyour freshly tilled or cultivated soil. Footprintscausesoil compaction that can hamper root penetrationand contribute to soil erosion. Theycan also "plant" unwantedweed seedsback into the freshly tilled ground.

In very hardground it may takethree or four overlapping passesto thor- oughly pulverizethe soil. (SeeFigure 4-8.)

•If the garden sizewill not permit lengthwise and then crosswise tilling, then overlap the first passesby one- half a tiller width, followed by succes- sive passesat one-quarter width (see Figure4-8).

•With planning, you can allow enough room betweenrows to cultivate (see Figure4-9). Leaveroom for the hood width, plus enough extra room for future plant growth.

Tilling depths

• When preparing the soil, till a fresh

path on each passrather than overlap-

maximum traction on undisturbed soil.

SeeFigure4-6. Dig as deeply as

possible on each pass without over-

loadingthe engine. Later passescan

be overlapped. (Watering the garden

With experience,you will find the "just right" tilling depth andtilling speed combination that is bestfor your garden.

Set the enginethrottle lever at a high enough speed to give the engine adequate power and yet allow it to

Suggestedtilling patterns

•When preparinga seedbed,go over the same path twice inthe first row, then make individual passes right next to each other (see Figure4-6). When finished in one direction, makesecond passes at a right angle as shown in Figure 4-7.
