About Ag Plant Tools

Ag Plant Tools builds simple tools for ag retailers and farm operations. FieldLog keeps fertilizer and spray application records inspector-ready. The Used Equipment Analyzer scores used machines from your photos. The guides are printable PDF checklists for buying used equipment with confidence. And every ROI calculator answers one question: does this equipment pay for itself?

Each calculator is a straightforward Excel spreadsheet. You plug in your own numbers — labor rates, throughput, operating costs, acres or tons — and it gives you payback years and net benefit. No black boxes, no 40-tab models nobody opens twice.
