I. Main Traveling Systems

1. Crawler Type (most common and mainstream)

Structure: left and right rubber tracks + drive wheels + guide wheels

Features:

• Large ground contact area, no sinking in mud, no damage to lawn or soil

• Strong climbing ability, stable climbing on 30°～50° slopes

• 360° in‑situ turning, high flexibility

• Excellent performance on complex terrain: slopes, river banks, mountains, muddy ground

Applications: slopes, orchards, photovoltaic power stations, wasteland, hills.

2. Four‑Wheel Drive (4WD)

Structure: 4 wheels, all powered

Features:

• High speed, high efficiency on flat ground

• Flexible steering, stable on flat terrain

• Much stronger grip than two‑wheel drive

Applications: flat lawns, parks, factory areas, sports fields.

II. Rarely or rarely used

• Two‑Wheel Drive (2WD): weak power, easy to slip and get stuck; seldom used in remote control lawn mowers.

• Three‑Wheel Type: poor stability, not suitable for complex terrain; very rare.

One‑sentence summary

• Mostly flat ground → Four‑Wheel Drive

• Mostly slopes, mud, mountains, complex terrain → Crawler Type
