Abstract

A dethatcher includes a frame having front and rear ends, a cover coupled to the frame and configured to selectively move between an open position and a closed position, a handle extending from the frame, multiple wheels coupled to the frame, a cutting reel housed in the frame, and an engine for powering a drive mechanism of the shaft. The cutting reel includes a shaft having a first end and a second end, at least one cutting mechanism located between the first end and the second end of the shaft, and the drive mechanism for powering the shaft. When the cover is in the open position, a user may access the cutting reel from a top end of the frame.

Claims (43)

1. A dethatcher, comprising:

a frame;

a cover coupled to the frame and movable between an open position and a closed position;

a handle extending from the frame;

a plurality of wheels coupled to the frame;

a cutting reel housed in the frame, the cutting reel comprising:

a shaft having a first end and a second end;

at least one cutting mechanism located between the first end and the second end of the shaft; and

a drive mechanism for powering the shaft; and

an engine for powering the cutting reel via the drive mechanism,

wherein when the cover is in the open position the cutting reel is exposed for removal from the frame through an opening in a top end of the frame; and

wherein when the cover is in the closed position, the cutting reel is concealed.

2. The dethatcher of claim 1 , further comprising an intermediate shaft, the intermediate shaft located below and powered by the engine.

3. The dethatcher of claim 2 , wherein the intermediate shaft includes a rake driving pulley, wherein the drive mechanism comprises a cutting reel pulley coupled to the rake driving pulley, and wherein the engine powers the rake driving pulley through the intermediate shaft, and the rake driving pulley powers the shaft through the cutting reel pulley.

4. The dethatcher of claim 1 , wherein the cover is pivotally coupled to the frame.

5. The dethatcher of claim 1 , wherein the cutting reel is removably housed in the frame by a first plurality of bolts and collars attached to the first end of the shaft and the frame and a second plurality of bolts and collars attached to the second end of the shaft and the frame.

6. The dethatcher of claim 5 , wherein when the cover is in the open position the cutting reel is further exposed for detachment from the frame by detaching the first plurality of bolts and collars from the first end of the shaft and detaching the second plurality of bolts and collars from the second end of the shaft.

7. The dethatcher of claim 6 , wherein when the cover is in the open position the cutting reel is exposed for replacement through the opening in the top end of the frame by a second cutting reel.

8. The dethatcher of claim 7 , wherein the cutting mechanism is at least one of a flail reel, a slicing reel, and a spring tine reel, wherein the second cutting reel comprises at least one second cutting mechanism, and wherein the second cutting mechanism is at least one of a flail reel, a slicing reel, and a spring tine reel.

9. The dethatcher of claim 1 , wherein when the cover is in the closed position the cover entirely covers the opening in the top end of the frame.

10. The dethatcher of claim 9 , further comprising a bagger, the bagger removably coupled to the frame and comprising:

a bagger frame;

a material surrounding and supported by the bagger frame, the material including a material opening.

11. The dethatcher of claim 10 , wherein the cutting reel is operable to remove debris including thatch.

12. The dethatcher of claim 11 , wherein when the cover is in the open position, the material opening aligns with the frame opening, and wherein the material receives the debris during operation of the cutting reel.

13. A dethatcher, comprising:

a frame having front and rear ends;

a cover coupled to the frame and movable between an open position and a closed position;

a handle extending from the rear end of the frame;

a plurality of wheels coupled to the frame;

a cutting reel housed in the frame; and

an engine for powering the cutting reel,

wherein a bottom of the engine is below a top of the cutting reel when the cutting reel is in use and wherein the cutting reel is located entirely in a front half of the frame; and

wherein when the cover is in the open position the cutting reel is exposed for removal from the frame through an opening in a top end of the frame.

14. The dethatcher of claim 13 , further comprising an intermediate shaft, the intermediate shaft located below the bottom of the engine and powered by the engine.

15. The dethatcher of claim 14 , wherein the intermediate shaft includes a rake driving pulley, wherein the cutting reel includes a cutting reel pulley coupled to the rake driving pulley, and wherein the engine powers the rake driving pulley through the intermediate shaft, and the rake driving pulley powers the cutting reel through the cutting reel pulley.

16. The dethatcher of claim 15 , wherein the cover is pivotally coupled to the frame.

17. The dethatcher of claim 16 , wherein the opening in the top end of the frame is located near the front end of the frame.

18. The dethatcher of claim 13 , wherein the cover does not cover the opening in the top end of the frame when in the open position and entirely covers the opening in the top end of the frame when in the closed position.

19. The dethatcher of claim 18 , further comprising a bagger, the bagger removably coupled to the frame and comprising:

a bagger frame;

a material surrounding and supported by the bagger frame, the material including a material opening.

20. The dethatcher of claim 19 , wherein the cutting reel is operable to remove debris including thatch, wherein when the cover is in the open position, the material opening aligns with the frame opening, and wherein the material receives the debris during operation of the cutting reel.
