Description

Classen RA-21H Quiet. Compact. Relentless. The Aerator Built for Pros

1. 450 Strokes Per Minute Reciprocating Tines

  • Rapid tine motion delivers dense, consistent soil penetration over large areas.
  • Users can complete jobs faster with better turf aeration results, enhancing root growth and lawn health, ideal for commercial contractors who need efficiency without sacrificing quality.

2. Lightweight Design with Easy End-of-Row Turning

  • The lighter build makes the unit easier to maneuver around landscaping obstacles and at tight turning points.
  • Reduces operator fatigue and speeds up turnaround time, making it more efficient for all-day jobs, even in small or irregularly shaped lawns.
     

3. Rust-Resistant Two-Piece Hood with Low Noise Output

  • Durable, weather-resistant construction that also dampens operational noise and simplifies maintenance access.
  •  Longer machine life with less downtime and a quieter experience for both operators and surrounding property owners, especially important for use in residential areas or noise-sensitive zones.

The Classen RA-21H Reciprocating Aerator is engineered to create clean, precise holes in even the toughest soil without the need for extra weights. Its innovative design delivers effective aeration while maintaining ease of use, making it ideal for both professionals and rental users. Like all Classen turf care equipment, this aerator emphasizes simplicity and reliability, featuring an open, user-friendly layout that provides quick access for maintenance and adjustments. Operator controls are straightforward and intuitive, reducing the learning curve and boosting productivity. Whether for commercial jobs or residential lawn care, this machine combines performance and practicality in one powerful, easy-to-use solution.
