Tilling Techniques

Proper technique improves results and reduces strain.

  1. Breaking new ground: Set depth regulator to shallow setting for first pass.
  2. Overlap passes: Overlap each pass by 2-3 inches for even coverage.
  3. Working pattern: Till in straight lines, then cross-till at 90 degrees for thorough cultivation.
  4. Weeding mode: Use reverse tine function to uproot weeds without deep tilling.
  5. Rocky soil: Work slowly and remove large rocks before tilling.
  6. Wet soil: Avoid tilling when soil is saturated to prevent clumping.

Tip: Let the tiller do the work - don't force it through tough soil.

Storage Guidelines

Proper storage prevents damage during off-seasons.

  1. Clean thoroughly: Remove all dirt and debris from tines and frame.
  2. Fuel treatment: Add fuel stabilizer or drain fuel tank completely.
  3. Oil change: Change engine oil before extended storage.
  4. Protect tines: Apply light oil to tines to prevent rust.
  5. Storage location: Store in dry, covered area away from moisture.
  6. Battery (if electric start): Remove and store battery separately.

CAUTION! Never store tiller with fuel in tank for more than 30 days without stabilizer.
