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 – The WYCO Screed King – WS621505 is a gas‑powered power screed unit built to significantly reduce manual labor and speed up concrete leveling with high‑frequency vibration that produces smoother, more uniform surfaces than hand screeding.
Easy One‑Person Operation – Designed so one operator can handle up to 16–20 ft screed boards, this unit cuts down crew size and fatigue on medium to large pours.
Comfort‑Focused Ergonomics – Adjustable handlebars and a cross‑beam design absorb up to ~75 % less hand vibration than competitors, improving comfort and control during long screeding runs.
Tool‑Less Setup & Cleanup – 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 – Magnesium screed boards float well across fresh concrete and resist reaction with concrete better than aluminum, helping achieve flat, professional finishes with less rework.
Maintenance‑Friendly Design – Sealed bearings and no flex‑shaft lubrication points mean near‑zero routine maintenance, keeping downtime and service costs low.
Expert Verdict – A durable, contractor‑grade power screed that boosts productivity, reduces physical strain, and delivers higher‑quality concrete surfaces — ideal for commercial pours, flatwork, sidewalks, and extended slab projects.
Q&A
Q: What is the WYCO Screed King (WS621505)? A: It’s a gas‑powered concrete power screed unit that uses vibration to level, consolidate, and finish poured concrete quickly and with professional results.
Q: How does it improve concrete finishing? A: Its high‑frequency vibration system eliminates honeycomb air pockets and settles fresh concrete efficiently for a more uniform, flat surface compared to traditional manual screeding.
Q: What powers the Screed King unit? A: The unit is equipped with a Honda GX35 4‑stroke gasoline engine, providing reliable power without needing cords or external power.
Q: Can one person use it? A: Yes — it’s designed so a single operator can screed concrete boards up to 16–20 ft (boards sold separately) with minimal effort.
Q: What makes the screed boards effective? A: The Magflo magnesium screed boards are lightweight, won’t 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 cross‑beam handle design absorbs vibration, reducing hand strain by up to ~75 % compared with non‑powered screeds.
Q: What lengths of screed bars are compatible? A: Boards are available from ~5 ft up to 20 ft to match job requirements (sold separately).
Q: Who is this tool ideal for? A: It’s 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 — the Magflo board’s smooth finish makes this quick and prevents concrete hardening on components.
Inspect Bearings & Seals: Although the power head uses factory‑sealed bearings that require minimal service, periodically check for signs of wear or vibration anomalies and replace worn parts.
Check Engine & Controls: On gas‑powered 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.
