Mwahahaha
Just got back in from using the brush hog for the first time. What a cool attachment. /w3tcompact/icons/grin.gif Mowed about 5 acres of 3-4' tall grass, and any bush/small tree that got in my way.
At any rate, the chain guards worked great. The rear one still looks new except for the grass all over it. I didn't see a stick or anything fly more than 5 feet. The front didn't fare so well - turns out the chain near the center was too long, despite making it shorter than the rest. The blades hacked off a lot of the chain, but in the process it bent the angle iron down a little (not too much). 5 minutes with a BFH fixed that, and I trimmed any chain left that was still too long. None of the loctited bolts came loose.
So, thumbs up except for me making the front chain too long. I think if I were to build them over, I would of used some thicker, wider angle iron to move the front guard away from the blades more.. But I think the pre-punched stuff I used will hold up.
BTW John, thanks for the other brush hog tutorial thread.. This is the first time I've used a brush hog and your tips made it a no-sweat process.
