Scotts Speedy Green Settings: 1000, 2000 & 3000

The Speedy Green line was discontinued years ago, replaced by EdgeGuard — but the spreaders themselves keep running, often for decades, while current Scotts bags no longer print a column for them. This page covers the cross-reference method that fills that gap, a wear adjustment for older units, and general upkeep for keeping one calibrating accurately.

Speedy Green Setting Estimator

Estimate a starting dial via the EdgeGuard cross-reference, with an adjustment for well-worn units, or work out product needed from any bag's rate.

Why no official Speedy Green chart exists anymore

Scotts replaced the Speedy Green line with EdgeGuard years ago, and manufacturer settings charts only get maintained for currently sold products — once a model is discontinued, its column quietly disappears from new bag printings. That leaves a real gap: the spreaders themselves are durable enough that plenty are still in active use, often having outlived several generations of the fertilizer they were bought to spread.

Scotts generally numbered the Speedy Green line by approximate hopper capacity — higher numbers typically indicating a later, larger unit — though exact specifications for the discontinued lineup were never published in one consolidated place the way current models are. Third-party spreader conversion charts consistently show the 1000 and 3000 tracking the EdgeGuard cross-reference exactly, while the 2000 runs about a full point higher at the same rate — the estimator above builds that adjustment in automatically when you select 2000.

Why the wear adjustment matters

A cross-reference assumes the gate opening on your unit still measures the same as it did new. On a spreader that's been through a decade or more of granular fertilizer — which is mildly abrasive and, left damp, mildly corrosive — that assumption gets shakier every year. Worn gate edges typically loosen the opening slightly, which means the same dial number lets more product through than it did originally. That's the entire reason for the "well-worn unit" checkbox above: it starts you a full point lower than the raw cross-reference, which is closer to what a decades-old gate actually delivers, but it's still an estimate. A calibration test strip is the only way to confirm the real number for your specific unit.

Keeping an old Speedy Green accurate

If the gate won't hold a consistent opening even after cleaning, or the wheels no longer drive the disc reliably, that's usually the point where a modern replacement becomes more accurate — and considerably less frustrating — than continuing to fight an old unit's guesswork.

If it's time to retire the old unit

A modern broadcast spreader↗ comes with a current, published settings chart — no cross-referencing required. Either way, a digital scale↗ turns a calibration test from a guess into an actual measurement.

FAQ

What are the settings for a discontinued Scotts Speedy Green spreader?

There's no current official chart — Speedy Green was replaced by the EdgeGuard line and Scotts stopped publishing settings for it. Because the dials use a comparable numeric range, the EdgeGuard cross-reference is the standard starting point; the estimator above applies it directly and adjusts for gate wear on older units.

What's the difference between the Speedy Green 1000, 2000, and 3000?

Scotts generally numbered the line by hopper capacity — higher numbers typically indicate a later, larger-capacity unit — but exact specs for the discontinued lineup were never published in one place. Third-party spreader conversion charts consistently show the 1000 and 3000 tracking the EdgeGuard cross-reference exactly, while the 2000 runs about a full point higher at the same rate; the estimator above builds that adjustment in automatically.

Why does an old Speedy Green need a lower setting than the EdgeGuard chart suggests?

Decades of use wear the gate opening, which tends to loosen it and let more product through at the same dial number. The "well-worn unit" adjustment above accounts for this by starting a full point lower — but a calibration test strip is the only way to know for certain.

How do I calibrate an old Speedy Green spreader?

Set the dial to the estimated starting point, weigh a known amount of product into the hopper, walk a measured 10×10 ft area at your normal pace, then weigh what's left. The difference tells you the actual delivered rate — compare it to the label rate and adjust up or down from there.

Is it worth keeping an old Speedy Green spreader running?

If it still calibrates consistently after cleaning the gate and checking the wheel-drive gear for wear, yes — these units were built to last and many run for decades. If the gate won't hold a consistent opening or the wheels no longer drive the agitator reliably, a modern broadcast replacement will be more accurate and less frustrating to dial in.

Important note

Settings on this page are an estimate derived from the current EdgeGuard chart, not a Scotts published Speedy Green source — none exists. Treat every number here as a starting point and confirm it with a calibration test strip before treating a whole lawn, especially on an older, well-used unit.
