    Default Changing Hog Blades.

    I want to change out my bush hog blades, they are chewed up pretty bad from clearing out my land (I'll post a pic soon).

    To change the blades, do i first take of the large bolt holding on the stump jumper and work on the blades while off the frame?

    Thanks! I sure wish I knew about this board before I bought my tractor, would of saved me a lot of money!

    Unfortunally, I do not have an access hole... I do have a drill....

    I assume "of" means "off", and if so, there are a number of threads on this site related to sharpening blades while still on a "brush cutter". Most use a Dremel Mototool, but that will take a (long) while if you have a heavy duty brush cutter and, therefore, thick blades. Try a higher voltage rechargeable drill with an appropriate attachment, or better yet use a "hard wired" one for higher rpm's. The salient point is to keep the blades relatively equal in weight, or your brush cutter, and tractor, will vibrate in proportion to the difference between the weights of the blades (amazing what a 1/2 ounce can mean at 7000 plus rpm on a 2.5 foot radius, my brush cutter -yup, I've messed this up, big time). Alternatively, you could take the blades off and have them commercially sharpened (no guarantee of equal weights), or you could order new blades, and sharpen them whenever they become "a little bit dull" (can easily do while still on the brush cutter, not a big deal if you are not shaving too much metal - what I do after the "learning experience"), so as to avoid a major tune up, which is when the imbalance problem could become an issue.

    RMEADOWS, I have a 6' Rhino mower. I have a hydrolic top link. If I raise the lower tractor arms and close the top link, the blades are very easy to get to for sharpening with a grinder. This method my not satisfy Osha but it works for me.

    The problem mine are torn up pretty bad. I need to replace them and I need to figure out what is the best way to get them off.

    Roger, I bought new blades for the 4' Bush Hog brand brush hog I had and was actually surprised at how cheap they were. But as far as how to remove them, it depends on what brand brush hog you have. My Bush Hog (and one Woods Brush Bull I've looked at) had an access hole in the deck, but my Howse did not and it would have been very difficult to get a wrench on the blade bolt nuts under the deck. I had to pull a very large cotter pin from the castellated nut on the output shaft of the gear box, then use a gear puller (I just used two 5" C clamps and a short, stout piece of iron - C channel) to pull the stump jumper off, then removed the blades from the stump jumper.
