Kenyon S550 7″ Sprinkler Head Trimmer

Designed for heavy-duty irrigation work, this Kenyon S550 model features a 5/8″ steel shaft with a powder-coated finish to resist bending and rust. The 7″ cutting diameter, achieved with a step plate, provides precise leverage to trim grass cleanly around sprinkler heads. A 33″ welded handle enables upright operation, reducing user strain during extended sessions. Ideal for mid- to large-diameter trimming tasks, it supports efficient mowing around heads without disturbing the irrigation itself.
Kenyon S550 2-3/4″ Sprinkler Head Trimmer

This compact option shares the same sturdy build as larger Kenyon models, featuring a 5/8″ steel shaft and a long 33″ welded handle for upright use. The 2-3/4″ cutting diameter is well-suited for trimming around smaller sprinkler heads, offering targeted precision with less overall effort. The step plate provides leverage for clean, circular trims close to the head, protecting irrigation components from grass encroachment.
Kenyon S550 4″ Sprinkler Head Trimmer

The 4″ cutting diameter version expands coverage for larger sprinkler heads. It retains the heavy-duty 5/8″ steel shaft and the 33″ welded handle, delivering strong leverage for cutting clean circles around sprinkler heads. The tool’s construction supports repeated use in professional or DIY irrigation setups, reducing fatigue while maintaining precision around heads and valve boxes.
Underhill TurboTrim 11 Inch Blade

The Underhill TurboTrim blade is designed to trim turf around golf sprinklers and is compatible with related TurboTrim tools. Made from heavy-duty steel with a powder-coated finish, it is positioned for commercial-grade performance. Installation is straightforward, and it’s suitable for professional settings such as golf courses and athletic facilities, where precise trimming around sprinkler heads is critical to maintain course aesthetics and irrigation efficiency.
Keyfit Tools Sprinkler Head Wrench

Keyfit Tools offers a versatile sprinkler head wrench designed to remove, replace, or adjust heads across all brands. It features an angled jaw for better access and outer jaw teeth for extraction, along with bottom teeth that engage the cap fins for body or cap removal with minimal digging. Compatible with a broad range of brands, this tool supports quick head maintenance and reduces the risk of damage to sprinkler components during service.
Keyfit Tools SpeedQueen Nipple Extractor

The SpeedQueen professional nipple extractor provides drill-powered removal of broken risers and fittings. Made from heat-treated 4140 steel and precision CNC machined components, it is designed for rapid, durable extraction in heavy-use environments. While it requires a compatible drill, the tool is built for contractor workloads and can dramatically shorten the time needed to resolve stuck components in irrigation systems.
ColourTree Sprinkler Tool Pack

This tool pack bundles essential spray rotor and hunter key tools for sprinkler maintenance. It’s a convenient option for homeowners or professionals who want a compact kit for routine adjustments, inspections, and head replacements. The pack is designed to cover common brands and head types, making it a versatile addition to any irrigation toolkit.
Buying Guide
- Head diameter compatibility: Choose tools with cutting diameters that match your sprinkler heads (2.75″, 4″, 7″ etc.) to ensure clean, precise trims.
- Build quality: Prioritize stainless or powder-coated steel shafts and rust resistance for durability in outdoor conditions.
- Leverage and ergonomics: A long handle and a sturdy step plate improve leverage and reduce strain during extended trimming tasks.
- Brand versatility: Tools like the Keyfit Wrench work across multiple brands and head types, reducing the need for multiple devices.
- Specialized tools: For golf courses or high-traffic irrigation, blade replacements (Underhill) and drill-powered extractors (SpeedQueen) can save time on tough jobs.
