Serrated blades on a Bush Hog....

I dust off a lot of mole hills with my Bush Hog 3008 mower. We have sandy/ gravelly soil, so it is abrasive. After a couple hundred hours the blades on my mower get serrations in them. I have found they cut better then. I have about 500 hours on this set and see no reason to replace them since they are cutting good....makes me wonder why they don't offer a serrated blade for these mowers?? I know a serrated sickle mower usually worked better than a smooth sickle....
 
I guess it depends on what you're cutting. If grasses, then a serrated blade will rip/tear more than a sharp straight blade will. And that last sentence contains a key word....sharp.

Bush hog blades are fairly thick. So while it may do a decent job of making tall stuff shorter, try taking a closer look some time using a magnifying glass at the cut ends of what you leave behind after a pass.

On the other hand, if nice, clean cuts help promote healthy growing, then why would you want to promote weeds/shrubs/unwanted trees into growing by using sharp blades?

My point? Don't have one. Been a long day and I'm beat, so feeling pretty pointless right now. *lol*
 
You have to remember that the whole premise of the Bushhog was to cut brush, the blades never were to be so sharp, or cut so good that they
left a sharp intact edge that would dry and harden, then stab a hole in the tire next time you mowered. They were meant to cut grass, but beat
the small bushes and trees to a shredded top that hopefully wouldn?t ruin a tire. We all, myself included tend to use them more these days to
cut fields that would been baled in the past.
 
The correct police will likely flame me on my bush hog blade sharpening procedure. I use the cutting torch to re-cut the bevel. I cut it back so the bottom of blade is flat. This also gives the serated effect. Has worked very well for me for 20 years or so...
 
I wont flame ya, I have done that myself a few times, sure beats grinding 3/4" off with a grinder especially when the blades are about shot anyway. Trick is a good clean tip and steady hand. I do knock them off a bit with a grinder afterward, just in case a brush hog blade policeman looks under it when I am not around, LOL

I like it! I have 5 or 6 old sets I could do that too. Any problems with balance?

Only when alcohol is involved. *lol*

When I had my (small) brush hog, it was used both in fields of grasses and in the woods. Was a Howse 5', and mounted some on a TO-30, other times on the Pasquali 986. Don't remember ever having anything left that would puncture a tire -- but then I used to be a LOT luckier than I am nowdays! *lol*
