RYOBI Salt Spreader OSS1800 18V ONE+ Body Only — 4L Hopper, Adjustable Flow & 2–3.5m Reach

The RYOBI OSS1800 is a cordless 18V ONE+ salt and seed spreader with a 4L hopper, adjustable flow and reach up to 2–3.5 m for quick, even coverage.

This lightweight, battery-powered spreader is designed to make scattering seed, fertiliser, salt or animal feed quicker and more consistent than hand-spreading. As a bare tool in the ONE+ family, the OSS1800 accepts any RYOBI 18V battery (recommended RB18L40 1.5Ah) so you can add it to an existing collection without buying a dedicated power pack. Built to resist clogging and to deliver a predictable spread pattern, the OSS1800 is aimed at homeowners and hobbyists who want tidy lawns, patios and garden beds with minimal effort.

How far and how evenly will the OSS1800 scatter material?

The spreader offers an adjustable distribution area and variable flow control so you can tune how much material exits the hopper on each pass. RYOBI states it can reach distances around 2 m and spread consistently across the set width, reducing the patchiness that results from hand-seeding.

• Adjustable spread width to suit small beds or wider paths
• Variable flow rate dial for fine or coarse application
• Consistent rotor action reduces clumping and missed areas

What capacity and materials does the 4L hopper handle?

The OSS1800 holds approximately 4 litres (around 5 kg depending on material density), large enough for most lawn or driveway jobs without being heavy to carry. It’s intended for free-flowing dry materials like grass seed, granular fertiliser, de-icing salt and dry animal feed.

• 4L capacity for fewer refills on medium-sized tasks
• Suitable for seed, fertiliser, salt and dry feed
• Lightweight design keeps the unit easy to maneuver

How does the spreader avoid blockages and stay reliable?

RYOBI fitted an anti-clog agitator inside the hopper to keep granular materials moving toward the outlet and prevent bridging. The simple mechanical design reduces maintenance and helps the tool run smoothly through a session without frequent emptying or manual unclogging.

• Internal agitator prevents bridging of damp or irregular granules
• Minimal moving parts for straightforward upkeep
• Durable body materials made for regular outdoor use

Which battery and warranty should I expect with this bare tool?

This listing is for the body only — batteries and chargers are sold separately — and it accepts any RYOBI 18V ONE+ battery. RYOBI recommends the RB18L40 1.5Ah for a good balance of runtime and weight and backs the product with a 3-year warranty.

• Compatible with all RYOBI 18V ONE+ batteries and chargers
• Recommended battery: RB18L40 1.5Ah for typical jobs
• 3-year manufacturer warranty for peace of mind

Who is this for? The OSS1800 is aimed at homeowners, gardeners and smallholding owners who want a faster, neater way to distribute seed, feed, fertiliser or salt across gardens, driveways and patios. If you already use RYOBI’s ONE+ batteries, this bare-tool option is a cost-effective way to expand your kit; if you’re scaling up winter maintenance or seasonal seeding, the adjustable spread, anti-clog design and compact 4L capacity make it a practical choice for routine outdoor tasks.
