Right, and it could come out at 12,000 fpm (135 mph). That can kill someone or an animal. Anyone doing this needs to very careful.

Totally agree with it being a safety aspect. This cutter is used away from people and livestock. Not advocating any extreme measures simply showing a problem in the thick grass we are cutting. We have always been taught to not be anywhere around a bush hog when it is mowing and it will not be used when people are around. Again, not advocating cutting the rear out; not through yet. Got to add some more material and want to try to make the original guard adjustable for outlet height.

Here are a few pictures from my BH27 84" 3" capacity
Looks like it has more clearance than the unmodified. But nothing like what the mods show little scared about that. Its much easier to take more off than to but it back especially with wood, steel is a little easier. I could see going to far seriously impeding cut quality as this will disrupt the vortex under the deck and probably let out much larger unprocessed material. I would probably bet that the opening clearance is a balancing act between too little discharge (clumping as a result) and to open resulting in little mulching

I'd venture to guess that the woods is probably not that much different behind the rubber than the others. Dumb question but Did the blades get put on upside down or did they forget to form the cutting edge? What your describing does not sound typical. I would not want to be anywhere near where that is operating. I ordered chains for mine because I've been hit by indirect (bounced) shrapnel thrown from a cutter












Good luck with your endeavors hope your buddy is successful is his quest.

Dang it, now I am now curious and need to go down to the barn tomorrow and look at mine behind the guards.
