Mowing time depends on lawn size and mower type. A 5,000 sq ft lawn takes about 43 minutes with a self-propelled gas mower, 75 minutes with a push reel, or 15 minutes with a riding mower. Obstacles like trees and flower beds can add 10–25% more time.
| Lawn Size | Push Reel | Self-Propelled | Riding Mower |
|---|---|---|---|
| 3,000 sq ft | 45 min | 26 min | 9 min |
| 5,000 sq ft | 75 min | 43 min | 15 min |
| 10,000 sq ft | 150 min | 86 min | 30 min |
| 1/2 acre (21,780) | 5.4 hrs | 3.1 hrs | 65 min |
Professional mowing services charge $30–$80 per visit for an average lawn. Small lawns under 5,000 sq ft cost $30–50 per visit. Lawns of 5,000–10,000 sq ft cost $50–80. Larger lawns over 10,000 sq ft cost $80–$150+ per visit.
Cool-season grasses (bluegrass, fescue) need about 25–30 mowings per year, with peak frequency in spring and fall. Warm-season grasses (Bermuda, Zoysia) need about 20–25 mowings per year, with peak frequency in summer.
| Season | Cool-Season Grass | Warm-Season Grass |
|---|---|---|
| Spring | Weekly | Every 10–14 days |
| Summer | Every 7–10 days | Every 5–7 days |
| Fall | Every 10–14 days | Every 14–21 days |
DIY mowing costs $100–$500 per year in gas and maintenance, compared to $800–$4,000+ annually for a professional service. However, DIY does not account for your time or the cost of the mower itself. If you value your time at $20/hour, mowing a 5,000 sq ft lawn yourself costs about $15 per session in time alone.
A self-propelled gas mower uses about 0.3 gallons per hour, a riding mower uses about 1.5 gallons per hour, and a zero-turn uses about 2 gallons per hour. Push reel and robot mowers use no gas. Annual gas costs range from $0 (electric) to about $250 (zero-turn on large lawns).
