    Just wondering about scraping away grass clumps so it doesn’t rust. Also if I need to sharpen blades. I was thinking lifting up one side with the forks but I think there’s a danger to keeping your forks up with the tractor off

    I hang mine over a bank and crawl under it to grind blades.

    Lift mine high as it will go and 2 car jacks; 1 under each side sharpen blades while under

    I have taken my bush hog blades off to sharpen but the last couple of times the air wrench wouldn’t budge the large nuts so raised up, supported with jacks and crawled under with a cordless grinder. Not my favorite thing to do but it works :emb:

    Edit: I haven’t found it necessary to clean out the underside as it stays pretty clean, however I try never to mow when fields are wet.

    I tried keeping them sharp but then realized that they are a blunt instrument like a weed wacker string. No more sharpening. To clean under the deck I would brush hog something woody.

    I miss the tractor days. I sold the whole mess a few years ago.

    Highbeam That’s actually more accurate. I don’t sharpen as much as dress the cutting edge in the event that there was a ding from a rock or something. Just clean them up a bit.

    Cleaning is not as important as getting it dried out as quickly as possible. Don't park it in the weeds, keep it up on blocks ect.

    My bush hog is over 50 years old, the underside has NEVER been cleaned to my knowledge but has always been stored up on cement blocks for air flow and on a surface with no grass growing under it. It has never been kept inside a building. It was owned either by my dad, my brother, or myself for it's whole lifetime.

    I know the blades have been sharpened or "touched up" maybe four or five times over it's whole life and never been replaced.

    It was never really abused, but never pampered either. It gets less use now that I got a finish mower 4 years ago but it still does the "rough" stuff around the farm. The tail wheel has really been the only trouble spot... It's been welded back on and braced several times over the years. A few cracks in the body have been welded as well after some wicked rock strikes...
