Tractors and rovers both have to go over rough, uneven ground, so they share the same core design ideas: wide or tracked wheels for traction, high ground clearance to avoid getting stuck, a low center of gravity to stay upright, and a strong suspension to absorb shocks. The materials and exact specs differ—Mars rovers need radiation‑tolerant, lightweight composites, while tractors use heavy steel for earth‑toughness—but the underlying engineering principles are the same, just tuned for their specific environments.

Exactly, the core problem is the same: move over uneven terrain without tipping or breaking. For tractors you crank up the mass and torque to haul loads; for rovers you optimize for low mass, radiation shielding, and power limits, but the wheel‑or‑track design, suspension, and traction control stay essentially the same. It's all about translating the same fundamental mobility concepts into the constraints of each environment.
