I have used a 6' york rake on my BX 2200 for a variety of jobs. Depending on the material you are working, a full rake may cause turf tires to lose traction.
If you buy a rake, consider the guide wheels, as the BX does not have position control. The wheels (adjustable)allow the rake to "float", following the ground contour, resulting in a smooth & level grade.
Grading topsoil, sand, gravel driveways etc., a 6' rake is a good investment for the BX.
