2025 Ryan® Dethatcher & Overseeder DT20
Heavy-duty and built to perform, the Bobcat® DT20 places seeds directly into soil slits for fast germination and unmatched seed-to-soil contact, aeration, and overseeding.
- Overseeder with dethatching capabilities through a simplified transition process to exchange flail reels between the functionality.
- Cover 18,700 square feet per hour with a 19 in. working width
- Without any tools, easily change between five different reel types
- Self-propelled operation
- Overseed with confidence. Seed flow rate is easily controlled right from the operator’s station and stops automatically when the reel is raised.
- Adjust durable cutting blades down to a depth of .25 in. while seeding at variable rates for different grass varieties and applications.
- Experience maximum germination with curve-shaped discs that place seeds directly into soil slits for unmatched seed-to-soil contact.
- Finish jobs without feeling exhausted with self-propelled operation, delivering a consistent ground speed that makes for better results.
- Independent ground and reel drive with a transport lever make it easy to move around the jobsite.
Features may include:
Productive Working Width- Whether you’re working in tight areas or tackling large lawns, Bobcat dethatchers (or overseeders) cover more ground. Command 19 inches of dethatching width with every pass, depending on the model.
- A simple height adjustment lets you fine-tune your dethatcher's slicing depth. (Exact depths depend on blade type used).
- The Bobcat D20 overseeder places seed directly into the soil slits for a germination rate of over 90% for lush, rejuvenated lawns. The seed flow rate can be easily controlled from the operator's station and stops automatically when the reel is raised.
- Standard turf tires improve your traction and maneuverability while minimizing damage to turf.
- Bobcat dethatchers feature a heavy-duty frame and durable construction for years of reliable service.
- The 11 hp Honda GX390 engine provides all the power and performance you need to tackle the most challenging projects.
- All controls are conveniently located at the handlebar for convenient operation.
- The transport lever allows you to quickly engage or disengage the dethatcher (or overseeder) for an effortless transition from working mode to transport mode and back.
- With the self-driven drivetrain, you’ll get reliable, smooth performance and easy operation that minimizes fatigue.
- In addition to overseeding, the DT20 can be converted to dethatch, power rake or verticut by installing a flail reel or choice of fixed blade.
- The 40-pound seedbox provides productive seeding performance. Plus, a handy seed germination chart makes it easy to set seed application for the task.
