Motivation

The objective was to replace several specialized machines with one affordable, multi-function platform without sacrificing the core operations small farms rely on. Small-scale farmers often cannot afford multiple specialized machines, which raises operating costs and limits productivity — the project set out to combine several field operations onto one affordable platform.

Methodology

• Literature Review: Reviewed prior research on multipurpose agricultural machinery, fertilizer distributors, seed-sowing equipment, and small tracked vehicles to ground the design in existing work.
• Requirement Analysis: Ran market surveys and problem identification to define the operations the vehicle needed to perform.
• Concept Development: Produced rough diagrams of the cultivator, cutter, and row maker, then a conceptual solid model combining all three onto one chassis.
• CAD: Modeled the full assembly and selected materials — structural square pipe, angled GI pipe, and metal sheet — based on market pricing and availability.
• Prototype: Fabricated the vehicle from a scrap rickshaw base, building the front extended body, steering assembly, cutter assembly, and cultivator shaft.
• Evaluation: Tested the cultivator under load, identified a shaft-twisting failure from overloading and low-grade bearings, and resolved it with a solid shaft and upgraded bushed bearings.
