Gas lawn mower prices typically range from $250 to $2,500, with most residential walk-behind models costing about $450-$800. Engine power, cutting width, self-propelled drive, brand, and whether the mower is a push, riding, or commercial model drive the final price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Push mower | $250 | $400 | $650 | Typically 20-22-inch deck |
| Self-propelled mower | $400 | $650 | $1,000 | Residential, gas-powered |
| Riding mower | $2,000 | $3,500 | $5,500 | Entry-level lawn tractors |
| Commercial walk-behind | $1,500 | $3,000 | $5,000+ | Heavy-duty use and components |
Gas lawn mower prices by mower type and deck width
A basic push mower with a 20- or 21-inch cutting deck usually costs $250-$500. A 22-inch model with a stronger engine, bagging system, or washout port commonly runs $400-$700. These prices generally cover the mower only, before sales tax, fuel, and optional accessories.
Self-propelled walk-behind mowers often cost $450-$900, while premium residential versions may reach $1,000. A riding mower is a separate price tier: small lawn tractors often start near $2,000, and larger decks or stronger engines can push prices above $5,000. For a typical suburban yard, a $450-$800 walk-behind mower covers most routine mowing needs.

What the mower quote includes beyond the engine
Engine size affects capability, but drive system, deck construction, and included equipment also explain price differences. The ranges below are approximate portions of a new residential walk-behind mower’s price, not additional charges that every seller itemizes.
| Quote component | Low | Average | High | What changes the price |
|---|---|---|---|---|
| Engine and controls | $120 | $220 | $350 | Brand, displacement, starting features |
| Deck, wheels, and frame | $90 | $160 | $280 | Deck width and material |
| Drive system | $0 | $100 | $220 | Push versus self-propelled |
| Bag, mulch, or side-discharge parts | $0 | $40 | $100 | Included accessories and configuration |
| Retail overhead and assembly | $20 | $70 | $150 | Dealer setup and local service |
Self-propelled drive and a wider deck usually account for more of the price jump than small convenience features. A steel deck is common on residential machines; heavier-duty materials and commercial-grade components can raise the purchase price substantially.
How engine size and deck width change the price
Many standard walk-behind mowers use engines around 140-190 cc. Models at the lower end are generally suited to smaller, relatively level lawns, while a higher-displacement engine may cost more and provide added reserve for thick grass or frequent use. Engine displacement alone does not guarantee cutting quality, so buyers should compare the complete mower specification.
Deck width also affects both cost and mowing time. A 20-21-inch deck is often the budget choice; moving to 22-24 inches can add roughly $50-$200, depending on drive type and build. Slopes, narrow gates, and many landscaping obstacles can make a wider deck less convenient even when it trims passes on open ground. For yards above roughly half an acre, compare mowing time and maneuverability before paying extra for width.
How much does delivery, assembly, and upkeep add?
Retailers may include basic setup, but delivery and final assembly can add $25-$100 for a walk-behind mower. Riding mower delivery commonly costs $50-$150 or more, depending on distance and unloading requirements. Ask whether the quote includes oil, fuel, blade installation, and a ready-to-mow inspection.
Routine first-year supplies may add $20-$60 for oil, a spare blade, and fuel treatment. A replacement blade often costs $15-$40, while a basic tune-up at a small-engine shop may run $75-$150, excluding major repairs. If service is billed hourly, rates commonly fall around $75-$125 per hour, with parts extra.
Confirm delivery, setup, and maintenance charges before comparing dealer quotes with online prices.
When is a self-propelled mower worth its higher price?
A push mower saves money and suits a small, mostly flat lawn where the operator can comfortably manage the machine. Self-propelled models can be easier to use on larger lots, modest slopes, or thick turf, but their additional drive parts may increase purchase and repair expense. A front-wheel-drive model is generally intended for flatter ground; rear-wheel-drive systems can offer better traction on slopes.
For a lawn around a quarter acre or less, the lower purchase price of a push model may be more valuable than powered travel. For frequent mowing on a larger property, paying an extra $150-$350 for self-propelled drive may reduce effort. The best comparison is the added price against how often and how far the mower will be pushed.
What regional prices and seasonal deals look like
Local prices can differ with dealer competition, freight, sales tax, and demand. In high-cost metro areas, dealer pricing and delivery may be about 5%-15% above a lower-cost rural market; limited inventory can narrow that gap. Taxes are additional and vary by location, so the checkout total may differ even when the advertised price matches.
Demand usually rises in spring, when popular models may sell at list price or become temporarily unavailable. Late-season promotions can reduce select models by about 10%-20%, especially when retailers clear current-year inventory. Compare the delivered, assembled price rather than relying on the advertised discount alone.
Should an older gas mower be repaired or replaced?
A carburetor cleaning or tune-up may cost $75-$200, while a blade, cable, or wheel repair can often be handled for $20-$100 in parts and labor. Engine replacement or major transmission work can reach $250-$600 or more, making it harder to justify on an older basic mower.
Compare the written repair estimate with the price of a comparable new mower, including delivery and setup. Repair often makes sense when the deck is sound and the engine or drive issue is limited; extensive rust, repeated failures, or a repair bill near half the replacement cost favors shopping for another mower. Ask the shop to identify parts and labor separately before approving major work.
Ways to lower the gas mower purchase price
Start with the lawn’s actual area, slope, gate width, and mowing frequency, then avoid paying for a wider deck or drive system that will not help. Compare at least three local quotes and check what each includes. A sale mower with basic bagging may be a better value than a premium trim package if the extra features will go unused.
Consider a previous-season model, but verify warranty coverage, parts availability, and whether assembly is included. For a clean, lightly used mower, inspect the deck for rust, test cold starting, check for smoke, and confirm that the blade and drive engage properly. Keeping the specification simple and comparing out-the-door quotes are the most dependable ways to control the final price.
