App Concept

ShaftSaver Rust Breaker

A specialized hydraulic puller kit designed for tapered shafts on agricultural and lawn care equipment. It applies controlled, high-force pulling while simultaneously applying penetrating oil under pressure, safely separating seized components without bending or breaking parts.

Key Features

Integrated hydraulic ram with pressure gauge for precise force application
Penetrating oil injection port at the shaft interface
Interchangeable adapters for various taper sizes
Heat-resistant ceramic heating element to expand the outer part

Target Users: Farmers, ranchers, lawn care business owners, and equipment repair shops maintaining old bush hogs, mowers, and PTO-driven implements.

Revenue Model: $249 one-time purchase for the kit, $19 for replacement penetrating oil cartridges.
