A Walking Tractor with a Rotary Tiller (also called a two-wheel tractor with rotavator) is a small agricultural machine used for soil preparation. It combines a walking tractor (power unit) with a rotary tiller attachment to break, mix, and level the soil before planting. The machine typically consists of a diesel engine, gearbox, handlebars for control, two drive wheels, a power take-off (PTO) shaft, and the rotary tiller unit, which includes rotating blades (tines) enclosed in a protective cover.

In operation, the engine generates power and transmits it through the gearbox to both the wheels and the PTO shaft. The PTO drives the rotary tiller blades, causing them to spin at high speed. As the operator guides the machine forward using the handlebars, the rotating blades dig into the soil, cutting, crushing, and turning it over. This process loosens compacted soil, mixes in crop residues or manure, and creates a fine seedbed suitable for planting. The depth and speed of tilling can be adjusted depending on soil conditions. The operator walks behind the machine, controlling direction, speed, and blade engagement. This machine is efficient, easy to operate, and ideal for small farms, reducing manual labor while improving soil quality for better crop growth.
