central - east central Minnesota - | jdflyer - 9/30/2013 12:22 I'm a sorry photographer but I tried to get some shots of the condition of my blades. They are about five years old now. Local welding shop says if they try to sharpen bush hog blades it takes too long and doesn't last. I know a bush hog will never cut a slick as a lawn mower but these are starting to leave a more ragged cut. And you can see that the ends are getting rounded over.
If that's a rought cut brush and ditch type grass cutter . . . . Sharpen them yourself.
I sharpen my blades at least once a day (morning, before starting) and may even hit them again if I get into rocks or dirt banks.
I've sharpened half the blade away.
Most of the time, I can sharpen them on the mower - if I really bung them up (rocks), then I have to take them off.
I've bent plenty of blades also, I take them to the fabricator/welder guy and he has a hydraulic power press. We get'tem streighten out again and away I go. I have 2 sets of blades, incase I bend a blade or two. I can change them out and go and fix / sharpen later.
I use a 4½ in angle grinder with a #40 grit flap disk to sharpen blades. The flap disk doesn't heat up the blade, like a composite disk will.

When do you replace bush hog blades?
