Implement & Operation	Recommended Size	Workload Rating	Engineering Notes
Moldboard PlowPrimary Tillage	1 to 2 Bottom (12")1 - 2 铧 (30 cm)	Light Duty	Ideal for garden plots and light sandy soil.
Rotary Cutter / MowerMowing & Clearing	4 ft (48 in)1.2 m	Light Duty	Pasture clipping and light brush under 1" diameter.
Rotary TillerSeedbed Prep	42 to 48 in105 - 120 cm	Light Duty	Covers compact tractor tire width.
Disc HarrowSecondary Tillage	5 to 6 ft (16-18" discs)1.5 - 1.8 m (40-45 cm 耙片)	Light Duty	Small acreage soil break-up and secondary aeration.

Sizing & Soil Condition NoteActual implement sizing varies depending on local soil conditions (heavy clay vs sandy loam), field slope, and operating speed. Heavy tillage implements may require front ballast weights and wheel weights.
