EarthWay Spreader Settings: Dial, Trays & the Two-Pass Method

EarthWay EV-N-SPRED spreaders (2150, 2600A-Plus, and siblings) are the step up from big-box units — and their settings system has two features no other homeowner brand has: a wide 0–30 dial and three interchangeable output trays that completely change what every dial number delivers. Miss the tray detail and every chart on the internet will steer you wrong. This page covers the dial, the trays, EarthWay's two-pass convention, and a tray-aware dial finder.

⚠️ Before using any EarthWay setting — check your tray color. Look under the hopper: red = Standard output (pre-installed on all models), black = Low output, blue = High output. Each tray needs very different dial numbers for the same rate; wrong-tray settings are the #1 cause of major over- or under-application on EarthWay spreaders.

Enter the bag rate, pick your installed tray and pass method — get a starting dial number with the two-pass math handled.

The 0–30 dial: more resolution, more responsibility

EarthWay's dial runs from 0 (gate closed) to 30 (fully open) — roughly twice the resolution of a Scotts-style 2–15 dial. That's genuinely useful: fine rate control, and enough headroom for everything from 1 lb/1,000 pre-emergents to heavy organic rates. The trade-off is that small dial errors matter less but tray and pass-method errors matter more, because the wide range makes very wrong outputs possible without the dial looking obviously wrong.

A subtlety from EarthWay's own manuals worth knowing: settings assume a brisk ~3 mph walk, and the higher the dial, the faster the hopper empties — which means less time to close the gate when you slow down or stop to turn. It's one of EarthWay's stated reasons for preferring the two-pass method at lower dial numbers over one pass at a high number.

The Flex-Select tray system

The tray is the plastic insert forming the hopper floor and gate holes. EarthWay ships every EV-N-SPRED with the red Standard-output tray installed; the black Low-output tray (for fine, dense, low-rate products like some pre-emergents and greens-grade materials) and blue High-output tray (for bulky, high-rate materials — organics, lime, ice melt) are sold separately.

Why it exists: gate geometry that meters a fine 1 lb/1,000 product precisely would need to be nearly closed for it, where flow is inconsistent — and wide open for a 13 lb/1,000 organic, where the dial runs out of range. Swappable trays keep the dial in its accurate middle range for each product class. The consequence: every published EarthWay setting is tray-specific. EarthWay's Setting & Rate Guide publishes per-tray values; the finder above adjusts for tray, and any chart that doesn't say which tray it assumes should be treated as Standard-red — cautiously.

The two-pass convention (and the half-rate confusion)

EarthWay recommends the two-pass method for rates above about 5 lbs/1,000 sq ft: set the dial for half the target rate, spread north–south, then spread east–west. The two half-rate passes add up to the full rate with far better evenness — and this is the single most misread part of EarthWay charts. Entries marked "2 pass" already show the half-rate dial number; running that number in one pass under-applies by half, and doubling it for one pass defeats the point. The finder makes this explicit: pick the pass method and it shows the dial for that method.

Starting dial numbers by rate for EV-N-SPRED broadcast models with the pre-installed Standard tray, following EarthWay's Setting & Rate Guide conventions. For the black or blue tray, use the finder — the numbers shift substantially.

Rate (lbs/1,000 sq ft) Typical products Dial — single pass Dial — two passes
2 Light fertilizers, pre-emergents 9 —
3 Standard synthetic fertilizers 11 —
4 Fertilizer + pre-emergent combos 13 9 (×2)
5 Heavier synthetic rates 15 10 (×2)
8 Starter fertilizers, light organics 21 13 (×2)
12.8 Milorganite Classic and similar organics — 18 (×2)

EarthWay's calibration method (shut-off test)

EarthWay's own procedure: get the bag rate per 1,000 sq ft; weigh out enough for a 200–400 sq ft plot, keeping at least ⅓ of a hopper in the unit so flow stays consistent; set the chart dial; walk the plot at ~3 mph; weigh what's left and compare. The hub's calibration check calculator does the arithmetic and tells you which way to move the dial.

Gear notes

A digital scale↗ makes the ⅓-hopper shut-off test a two-minute job. If you're spreading behind a mower or ATV instead of walking, a tow-behind spreader↗ is the right tool — see the Agri-Fab page for ground-speed effects on towed units.

FAQ

What do EarthWay spreader dial numbers mean?

The EV-N-SPRED dial runs 0 (closed) to 30 (fully open) and controls the hopper gate opening — higher numbers, larger opening, more flow. The number is specific to EarthWay's scale and to the installed Flex-Select tray; it doesn't correspond to any other brand's numbers or to a rate.

Why do my EarthWay settings seem way off from the chart?

Check the tray color under the hopper: red = Standard (pre-installed), black = Low output, blue = High output. Each needs very different dial numbers for the same rate — see the tray section.

What is the EarthWay two-pass method?

Half the target rate on the dial, two perpendicular passes. Recommended above ~5 lbs/1,000. Chart entries marked "2 pass" already show the half-rate dial — details above.

What settings does the EarthWay 2150 use?

The 2150 (50 lb commercial model) uses the standard 0–30 dial and Flex-Select trays, so all the logic on this page applies directly: dial from rate for the installed tray, two passes above ~5 lbs/1,000, calibrate with the shut-off method.

How do I calibrate an EarthWay spreader?

Bag rate per 1,000 → weighed test amount for 200–400 sq ft (keep ⅓ hopper minimum) → chart dial → walk at ~3 mph → weigh the remainder and compare. The calibration calculator does the math.
