Which of Two Mowers Is Actually Cheaper Per Acre?
Enter deck width, type, and purchase details for two mowers. This combines mowing speed with ownership cost into a true cost-per-acre comparison.
How this is calculated
Each mower's production rate comes from Mowing Acres per Hour, its ownership cost per hour from Equipment Hourly Cost. Cost per acre is ownership cost per hour divided by acres per hour. The mower with the lower cost per acre is the cheaper choice for this terrain.
Worked example
A 42-inch riding mower ($4,000, $800 resale) covers about 1.22 acres per hour at roughly $5.96/hour, about $4.89 per acre. A 60-inch zero-turn ($8,000, $1,500 resale) covers ground faster but costs more to own, the calculator resolves which effect wins for the numbers entered.
Common mistakes
- Comparing purchase price alone without factoring in production rate.
- Comparing acres per hour alone without factoring in ownership cost.
- Using a terrain that does not match where the mower would actually run.
Frequently asked questions
Why compare cost per acre instead of just speed?
A faster mower is not automatically the cheaper choice, a bigger machine usually costs more to buy, fuel, and maintain. Cost per acre combines both into one comparable number.
Does this account for the mower I already own?
Enter your current mower as Mower A and a candidate as Mower B, the comparison works the same way whether both are hypothetical or one is already owned.
What if the two mowers would run on different terrain?
This calculator applies one terrain setting to both mowers for a fair comparison. If they would genuinely run on different property types, run the comparison twice.
Does a higher purchase price always lose?
No, a more expensive mower that covers meaningfully more ground per hour can still win on cost per acre, this calculator shows which effect dominates for the numbers entered.
