If you have priced aerial seeding in the last year, you have probably seen two very different quotes land on your desk — a six-figure number from a helicopter contractor, and a fraction of that from a drone operator. The instinctive reaction is “the drone must be worse,” because the number is so much smaller. That is not quite right. The two tools live on the same spectrum but at opposite ends. Helicopters win on massive, flat, wind-driven jobs. Drones win on small, steep, pocketed, or access-limited jobs. In between, the math is close enough that it is worth running the numbers carefully.
This post runs those numbers, head-to-head, on three realistic job sizes: 50 acres, 500 acres, and 5,000 acres. All three are common in Western US reclamation and rangeland work. Before we get to the numbers, though, a fair comparison requires being clear about what each tool actually is.
The Two Tools, Honestly
Helicopter aerial seeding uses a manned rotorcraft — typically a Bell 206 or a Hughes 500 in the Mountain West — with a belly-mounted seed bucket, usually 1,200 to 1,500 pounds of capacity. The aircraft lays down seed at 60 to 90 knots over wide swaths, refills from a mix truck staged within 10 to 15 minutes of flight time, and moves enormous quantities of seed in a short flight day. On a 5,000-acre post-fire emergency seeding, a helicopter is typically the only economically viable option.
Drone aerial seeding uses a purpose-built, heavy-lift agricultural drone with a 50 kg broadcast spreader. The aircraft flies autonomous patterns at 15 to 20 mph, 10 to 15 minutes per battery, and is reloaded on the ground between sorties. One aircraft covers around 21 acres per hour under good conditions. Two aircraft with shared staging can approach 40 to 50 acres per hour in production.
The two aircraft are not competing for the same job. They are competing for the overlap zone — jobs in the 200-to-2,000-acre range where both are technically feasible — and helicopter contractors are losing that zone to drones almost everywhere we look, because the drone’s mobilization economics are so much better.
Cost per Flight Hour vs. Cost per Acre
The most common (and most misleading) way to compare the two is by flight-hour rate. A Bell 206 or 500 on a seeding contract in the Western US typically runs $1,500 to $3,000 per flight hour, not including mobilization, the pilot-and-ground-crew day rate, the mix truck and loader crew, or seed. Drone seeding is harder to benchmark on a flight-hour basis, but a useful figure is roughly $400 to $700 per aircraft-hour loaded with pilot, spreader, battery turnaround, and depreciation.
Those numbers make the helicopter look 3 to 5x more expensive, which is accurate as far as it goes. But they gloss over the real story: mobilization. A helicopter seeding operation almost always carries a fixed minimum cost floor — often $8,000 to $20,000 just to mobilize the aircraft and support crew — that has to be amortized across whatever acreage the job covers.
That floor is what makes helicopters uneconomic on small jobs and what makes drones so strong in the 20-to-500-acre tier.
The Numbers: Three Realistic Jobs
The estimates below are composite industry figures for 2026 Western US conditions — not quotes for any specific project. They are meant to illustrate the structure of the cost math, not to replace a real quote. Variables like travel distance, seed cost, site complexity, and wind can move any of these numbers 20 to 40 percent in either direction.
Job 1 — 50-Acre Post-Fire Pocket on Steep Ground
Scenario: A post-fire emergency seeding on 50 acres of a 35-to-55 percent slope in Moffat County, Colorado. Access via a two-track that stops 1.5 miles from the nearest part of the burn. Target rate of 10 pounds per acre of a native cool-season grass mix. Timing window: two weeks.
| Line item | Helicopter | Drone |
|---|---|---|
| Mobilization | $8,000–$12,000 | $500–$1,200 |
| Flight time | 1–1.5 hr @ $2,200/hr | 2.5 hr @ $550/hr |
| Ground / support crew | $2,500 | $1,500 |
| Seed & carrier (same both) | $2,500 | $2,500 |
| Total | ~$15,700–$19,800 | ~$5,900–$6,600 |
| Per-acre | ~$314–$396 | ~$118–$132 |
Drone wins decisively. The helicopter flight itself is faster, but the mobilization cost swamps it on 50 acres. This is the envelope where drones have essentially won the market: small, steep, post-fire work that used to fall through the cracks because it was too small for a helicopter and too rough for a tractor.
Job 2 — 500-Acre Oil-and-Gas Reclamation Project
Scenario: A multi-pad oil-and-gas pad reclamation project across 500 acres in Northwest Colorado, spread over five pads and their access roads. Varied terrain, some pads with road access and some without. Target rate of 12 pounds per acre of a native mix with some pelletized forb species. Timing window: six weeks.
| Line item | Helicopter | Drone (single aircraft, 5 days) |
|---|---|---|
| Mobilization | $10,000–$15,000 | $1,500–$2,500 |
| Flight time | 5–7 hr @ $2,200/hr | 25 hr @ $550/hr |
| Ground / support crew | $6,000 | $7,500 |
| Seed (same both) | $22,500 | $22,500 |
| Total | ~$49,500–$57,900 | ~$45,250–$46,250 |
| Per-acre | ~$99–$116 | ~$90–$92 |
This is the overlap zone. The raw numbers are close enough that other factors — how pocketed the terrain is, how many separate pads need individual mob/demob, whether the operator can run two drones concurrently — usually tip the decision. For the specific scenario above, the drone wins slightly on cost and wins more clearly on site impact (zero road damage from a helicopter’s support truck parade). For a single 500-acre contiguous mesa top, the helicopter might tip back.
Two drones instead of one would drop the drone total by another 15 to 20 percent on a job like this, because you are amortizing the same mobilization across more productive time.
Job 3 — 5,000-Acre Post-Fire Emergency Seeding
Scenario: A 5,000-acre post-fire emergency BAER (Burned Area Emergency Response) seeding on public land in western Wyoming. Mixed terrain, most slopes under 40 percent. Target rate of 8 pounds per acre of a certified weed-free native mix. Timing window: ten days.
| Line item | Helicopter | Drone (four-aircraft team, ~15 days) |
|---|---|---|
| Mobilization | $15,000–$25,000 | $5,000–$8,000 |
| Flight time | 45–65 hr @ $2,400/hr | 250 hr @ $550/hr |
| Ground / support crew | $25,000 | $45,000 |
| Seed (same both) | $150,000 | $150,000 |
| Total | ~$298,000–$338,000 | ~$337,500–$345,500 |
| Per-acre | ~$59.60–$67.60 | ~$67.50–$69.10 |
Helicopter wins, but less dramatically than most people assume. And critically, the helicopter hits the ten-day timing window comfortably while the drone team is pushing hard to fit in fifteen days. On this kind of job — large, flat-ish, time-critical — helicopter is still the right tool. Drones may play a supporting role picking up the 500 acres of steep pockets the helicopter can’t safely cover, but the primary aircraft is still rotorcraft.
Beyond Cost: Four Factors That Often Matter More
Cost per acre is the headline number, but it is rarely the only thing that decides a job. These four factors often tip the decision one way or the other before a quote is even compared.
Mobilization speed. Drones typically mobilize in 2 to 5 days for regional projects. Helicopter contractors often have a 2-to-4-week lead time on availability, and emergency post-fire windows are weeks, not months. For a reclamation manager trying to get seed down before a forecasted storm, the drone’s faster mobilization is often the deciding factor regardless of cost.
Ground impact. Helicopter operations require a support truck, a mix crew, a fuel truck, and a staging area big enough to land the aircraft and turn trucks around. On fragile post-fire ground or active oil-and-gas pads that are mid-reclamation, that footprint is itself a source of damage. Drone operations need a 20-by-20-foot staging pad and a pickup truck. For pipeline right-of-way reclamation, that difference is often worth money on its own.
Coverage quality on complex terrain. Both aircraft use GPS for navigation, but drones use active phased-array radar for terrain following. On rolling and pocketed ground, drones maintain a more consistent height above terrain — which means more consistent swath width and application rate. Helicopters rely on pilot skill for terrain-following and are excellent in the hands of a good ag pilot, but the consistency-on-steep-ground advantage generally goes to the drone.
Documentation and reporting. Drones export as-applied coverage maps as a built-in feature of the flight controller. Helicopter operators can do this with aftermarket GPS logging systems, and most commercial contractors do, but it is more manual and less consistent. If your reclamation plan requires a formal coverage record (and most BLM and state reclamation specs now do), the drone workflow is usually cleaner.
Where the Math Actually Shifts
Distilled to a practical rule:
- Under ~200 acres, especially on steep or pocketed terrain, drone seeding is almost always cheaper and often faster. This is the drone’s home turf.
- 200 to 1,500 acres, the cost math is close. The decision is usually driven by terrain complexity, timing, and ground-impact concerns. If your site is pocketed, post-fire, or mid-reclamation, drone. If it is contiguous, accessible, and clean, helicopter.
- 1,500 to 3,000 acres depends heavily on how many drones the operator can field and how tight the timing window is. Well-capitalized drone operators with four-aircraft teams are now competing credibly in this tier.
- Above 3,000 acres, especially with tight timing, helicopter is typically still the right tool. Drones play a supporting role for the steep pockets.
The Bottom Line
The honest comparison is that drones and helicopters are complementary, not competitive, across most of the range — with significant overlap in the 200-to-2,000-acre tier where drones are winning more jobs every year on the strength of mobilization economics. Helicopter contractors who tell you drones can’t do your job are almost certainly wrong if your job is under 500 acres. Drone operators who tell you they can beat a helicopter on a 5,000-acre clean-terrain job are almost certainly wrong.
Our rule at MWDS is simple: if your site fits in the drone envelope, we will quote it honestly and aggressively. If it doesn’t, we will tell you so on the first call and point you to a helicopter contractor we trust. Aerial seeding is a small enough industry that the long-term reputation of giving straight answers is worth a lot more than the revenue from any one badly-fitted job.
