WYCO Screed King - WS621505
The Screed King is easy to use and saves time and manpower while providing the best finished concrete quality. The unique power bar and power transfer system produces a high-frequency vibration that eliminates the honeycomb effect and reduces finishing time. Screed boards are available in multiple lengths from 4 to 20 feet. Screed King also allows one person to do the work of two in less time as compared to traditional 2x4 screeding.
What our Experts Think
-
Pro Contractor Concrete Screeding Power â The WYCO Screed King â WS621505 is a gasâpowered power screed unit built to significantly reduce manual labor and speed up concrete leveling with highâfrequency vibration that produces smoother, more uniform surfaces than hand screeding.
-
Easy OneâPerson Operation â Designed so one operator can handle up to 16â20âŻft screed boards, this unit cuts down crew size and fatigue on medium to large pours.
-
ComfortâFocused Ergonomics â Adjustable handlebars and a crossâbeam design absorb up to ~75âŻ% less hand vibration than competitors, improving comfort and control during long screeding runs.
-
ToolâLess Setup & Cleanup â The Magflo magnesium screed boards are lightweight, sealed to resist concrete water entrapment, and install/remove without tools, making setup, teardown, and cleaning faster.
-
Superior Float & Finish Quality â Magnesium screed boards float well across fresh concrete and resist reaction with concrete better than aluminum, helping achieve flat, professional finishes with less rework.
-
MaintenanceâFriendly Design â Sealed bearings and no flexâshaft lubrication points mean nearâzero routine maintenance, keeping downtime and service costs low.
-
Expert Verdict â A durable, contractorâgrade power screed that boosts productivity, reduces physical strain, and delivers higherâquality concrete surfaces â ideal for commercial pours, flatwork, sidewalks, and extended slab projects.

A: The Magflo magnesium screed boards are lightweight, wonât react with concrete, float well on slumps, and are easy to clean with no tools required for removal.
Q: How does it reduce operator fatigue?
A: A crossâbeam handle design absorbs vibration, reducing hand strain by up to ~75âŻ% compared with nonâpowered screeds.
Q: What lengths of screed bars are compatible?
A: Boards are available from ~5âŻft up to 20âŻft to match job requirements (sold separately).
Q: Who is this tool ideal for?
A: Itâs perfect for concrete contractors, finishers, and builders who want faster leveling, better consolidation, and smoother finishes on slabs, footings, and floors.
Maintenance Tips
-
Clean After Each Pour: Remove concrete residue and buildup from the power head, handles, and board surfaces â the Magflo boardâs smooth finish makes this quick and prevents concrete hardening on components.
-
Inspect Bearings & Seals: Although the power head uses factoryâsealed bearings that require minimal service, periodically check for signs of wear or vibration anomalies and replace worn parts.
-
Check Engine & Controls: On gasâpowered units, keep the throttle linkage, spark plug, air filter, and fuel system clean and adjusted per engine manufacturer guidelines to ensure consistent power and vibration.
-
Secure Fasteners: Verify that handles, mounting clamps, and hardware remain tight before each use to minimize vibration loosening.
-
Protect Moving Parts During Storage: Store in a dry, covered area to prevent corrosion on the engine and power head; cover or elevate to avoid moisture contact.
