What the spec sheets actually say
Same brand. Same crew. Different tools.
If you're running a commercial crew you're not picking between brands — you're picking between two flagships from the same manufacturer. Husqvarna sells both. Stihl sells both. Here's how their own published specs line up, with a 2-year total cost of ownership built up from real-world commercial use.

* Operating-cost assumptions
- Use: 500 commercial-use hours per machine per year — a single tool shared across crew rotations.
- Fuel grade: mid-grade unleaded (89 octane). Husqvarna 580BTS specs 87 minimum with mid-grade recommended for sustained high RPM; Stihl BR 800 specs 89 minimum. Neither requires premium.
- Mid-grade gas price (NY metro, May 2026): ~$4.85/gal. EIA NYC retail data shows regular at $4.46–$4.56 statewide; mid-grade runs $0.20–0.30 higher and Westchester pumps have hit $4.99 for regular.
- Fuel rate: ~0.4 gal/hour averaged over real-world commercial throttle profile (manufacturer specs are at full load).
- 2-stroke oil: 50:1 mix at $15/quart.
- Electricity: $0.20/kWh commercial depot rate; ~0.3 kWh per machine-hour.
- Maintenance: spark plugs, air/fuel filters, carb cleaning, vibration mounts, plus one full scheduled service per year for the gas units.
- Excluded: labor, transport, hearing PPE, OSHA noise-compliance overhead, battery replacement (1,000+ cycle pack life keeps it out of the 2-year window).
How to read this
- Battery wins ~90% of the work. Mowing-day cleanup, edging, sidewalks, weekly clippings — the equipment finishes the job. Crews in every Westchester town that's banned gas are already running these every week.
- Time budget at peak wet leaves. In the few Northeast fall weeks when leaves are wet and matted on large lots, commercial-equivalent electric takes about 10% longer — a 40-minute property runs ~44 minutes. A scheduling adjustment, not a tool change.
- 2-year totals flip the sticker price. Battery costs more upfront; gas costs more to feed. Fuel alone: ~$2,400/machine over 2 yr at Westchester mid-grade ($4.85/gal). Battery electricity over the same window: under $150.
- Downtime. A gas blower that won't start in October is a lost morning of revenue. A spare battery costs less than a service call.
- The operator's ears. Battery is 19–33 dB(A) quieter at the operator's ear — perceptually 4–10× quieter. OSHA's 8-hour PEL is 90 dB(A); the gas Husqvarna at 106 dB blows through it in under 15 min.
- OSHA hearing-conservation overhead. Sustained >85 dB(A) triggers a written program (dosimetry, audiograms, PPE, training). Gas triggers it; battery doesn't.
Sticker price favors gas. Two-year TCO doesn't. Five-year isn't close.
