Precision Application · Part 137 Certified
Noxious weed control, spot treatment, fence lines, and liquid fertilizer — applied with a drift-conscious 40 L system on ground too steep, wet, or soft for a rig.

Precision Drone Spraying
Mountain West Drone Services applies herbicide, liquid fertilizer, and foliar products with a 40 L spray system built around twin rotary atomizers — adjustable droplet sizing, variable-rate flow control, and active terrain following. The result is even, documented application on the slopes, draws, fence lines, and wet ground that sideline ground rigs and aren't worth a plane's ferry bill.
Where Drone Spraying Earns Its Keep
Targeted treatment of cheatgrass, thistle, whitetop, and other listed weeds across rangeland, pasture edges, and disturbed ground — without driving the infestation deeper on equipment tires.
Hit the patches that need product instead of blanket-spraying the whole field. Flight lines target mapped polygons, so chemical use and cost stay proportional to the actual problem.
Linear, hard-to-drive features are exactly what a drone covers cleanly — fence lines, ditch banks, borrow ditches, and field edges without trampling adjacent ground.
Broadacre herbicide application across pasture and rangeland with terrain following over slopes, draws, and broken ground that sideline ground rigs.
Foliar nutrition and liquid fertilizer applied evenly at low volumes, on the timing your agronomy calls for — even when fields are too wet to drive.
When the sprayer rig would rut the field or simply cannot reach the slope, the aircraft holds a consistent application height with zero ground contact.
Why It Works
The aircraft carries its 40 L tank and twin rear-mounted rotary atomizers over the field at a consistent height, metering product at the rate you specify. Where a ground rig ruts, tramples, and tracks weed seed between fields — and a plane won't quote your acreage — the drone just flies the plan.
Every job closes with an as-applied map and application record, so what went down and where is never a question.
Rotary atomizers produce a controlled, adjustable droplet spectrum — fewer fines than conventional pressure nozzles, which means more product on target and less moving off it.
No wheel tracks, no ruts, no compacted rows — and no spreading weed seed or disease on equipment tires between fields.
Active phased-array radar holds application height over slopes, draws, and uneven ground, keeping swath width and rate consistent where booms struggle.
GPS flight logs and as-applied coverage maps with every job — documentation for your own records or regulatory needs.
Our Process
We talk through the target — weeds, timing, product, acreage, and any buffers or sensitive areas. You get a clear quote and an honest answer on whether drone application fits the job.
We map the treatment polygons, set swath, rate, and droplet size to match the label and conditions, and handle airspace authorization before the first flight.
On-site, the aircraft flies the plan with terrain following active. You receive an as-applied coverage map and application record when the job is done.
Questions We Hear
Liquid herbicides, liquid fertilizer, and foliar products, applied according to their label. The 40 L tank with twin rotary atomizers handles broadacre rangeland work as well as targeted spot treatment, fence lines, and ditch banks. If you are unsure whether your product is a fit for aerial application, send us the label and we will tell you straight.
Coverage runs up to 21 acres per hour under good conditions; realistic daily output depends on application rate, wind windows, water/mix logistics, and terrain. Spot treatment and linear work are quoted by the job rather than straight per-acre.
Rotary atomizers produce a controlled, adjustable droplet spectrum with fewer driftable fines than conventional pressure nozzles. We size droplets to the product and conditions, respect label wind limits and buffers, and fly with terrain-following radar so application height stays consistent.
Yes. Every job includes a GPS flight log and an as-applied coverage map showing exactly where product went down — useful for your own records, landlord reporting, or regulatory paperwork.
