I have a BX2200 and use a Woods LR106 72" medium duty rake.
It has a fold down grader blade and guide wheels.
This rake is for a larger tractor, but I wanted a contractor grade vs. a homeowner model. Your BX should have no problem picking a rake up. I use the rake or Woods GB48 box scraper as counter weight for loader work. I add 400 lbs. of weight to the box scraper, for an estimated 800lb. rear load. The tractor has been picking this up since April 2000 without any problem. Remember that weight equals traction, especially with a compact tractor.
My tractor has had no problem pulling the rake or plowing snow with the folddown blade. The wider blade does a better job leveling and grading.
One issue with the BX model is lift height with some implements. After a short time, I fabricated a jig that raises the lift height from the lower lift arms by 6". Before the jig, I could not raise the rake high enough to load it on my trailer.
I'll take a picture and try posting it.
Also, as the BX does not have position control, get the gauge wheels when buying the rake. The wheels will keep the rake a consistant depth in relation to the ground. It is practically impossible to try to keep a level grade using the 3 point lift control only.
I have 900 hrs. on my BX and after 5 years, I am still amazed at the work I have done, and what it can do. When the BX came out, many snickered at it as a baby tractor. You may have to take a smaller bite or pass, but the job gets done.
