Bout Width

Bout Width works out how long a field job will take and what it really costs, entirely on your phone. No account, no signal, no subscription. THREE QUESTIONS IT ANSWERS 1. Will this outfit finish the field inside the weather window? 2. Is owning this machine cheaper than hiring the work done? 3. Can the tractor actually pull the implement at all? WHAT A WIDTH-TIMES-SPEED CALCULATOR GETS WRONG - Effective width is nominal width MINUS overlap. Every lapped pass is work done twice, and an 8% lap on a sprayer is 8% of your day. - Field efficiency is not a book constant. Each headland turn costs roughly the same time whatever the field is, so the shorter the runs the more turns per hectare and the lower the efficiency. A drill in 200 m runs is a materially slower machine than the same drill in 800 m runs. - Fixed cost is spread over a YEAR of work, not over this job. Depreciation and interest are paid whether the machine moves or not, so the same implement is cheap at 400 ha a year and ruinous at 40. - The breakeven is derived, not guessed: annual fixed cost divided by what each hectare saves over the contractor rate. And when that rate is at or below your own running cost, owning never catches up at any area - the app says so rather than printing a large number. IT REFUSES RATHER THAN GUESSES Ask for a rate on an outfit that cannot physically go and you get the binding reason - too wide, too deep, soil too heavy, or simply too fast - along with the draft it needs, the drawbar power you have, and the fastest that tractor will pull it. A work rate for an impossible outfit is a number you would find out was wrong in the field. Leave the fuel burn blank and the own-or-hire comparison is withheld instead of being decided on an invented figure. WHAT IS IN IT - Tractor register with engine power, fuel burn, price, life and annual hours - Implement register with operation, width, overlap, depth, speed and annual area - Field register with area, soil class, run length, tags, pinning and archive - The full working shown line by line, so you can see which input drives the answer - Job log grouped by day, recording the rate you ACTUALLY achieved - Insights: achieved rates over time, hours by operation, fuel per area - Search, filter, sort and multi-select, with undo on every deletion - Export to JSON and CSV, restore from backup, or clear everything - Hectares or acres, metres or feet, and your choice of currency - Light and dark themes, four accents, optional compact density PRIVACY No account. No ads. No analytics. No third-party SDKs. No data collected and none shared. The app requests no runtime permissions at all. Its single network request is loading the privacy policy in Settings; everything else works in flight mode. Bout Width is a planning tool, not an agronomic or financial recommendation. Real ground, real weather and a real operator all move the figures.
