Precise Blade Adjustment
A simple height adjustment lets you fine-tune your dethatcher's slicing depth. (Exact depths depend on blade type used).
Slit Seeding Disc Delivery System
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.
Turf Tires
Standard turf tires improve your traction and maneuverability while minimizing damage to turf.
