Idea cooking ...
I actually have very little use for a lawn mower , what little "lawn" I
have is fairly weasily controlled with a weedeater . What I REALLY need is a bush hog , since much of what I'll be cutting will probably include small trees and such . I'm wondering if there's any reason I shouldn't fabricate a set of bush hog hubs/blades to replace the one-piece blades that I now have .. I realize there will be more load on the bearings/hubs/deck from shock loads , but they all need repair anyway and there's no reason I can't beef up the structure while I'm at it . And hey , it should still cut grass pretty well too . -- Snag |

They are free to swing back when they hit something like a stump that would tear up a single blade on a shaft. In my expierence, the heavier the better is the word on bushhogs. Deck needs to be heavy, as does the gearbox and stumpjumper |

Deck needs to be heavy, as does the gearbox and stumpjumper Exactly what I had in mind . A disc of say 1/2" steel with 2 stub blades of appropriate length to match the swing diameter of the single blade on there now (it has 3 blades) . I'm not planning on cutting anything bigger than say 3/4" diameter , and that will be stuff that I have already cut down . I recently repaired a hub that had the shield disc fatigued and cracked . That one was a 1" by 4" piece of steel about 3 feet long with a splined hub in the center . With the shield disc it weighed about 125 lbs . -- Snag |

Had about an inch and a half of the blade exposed. I did put a golf ball into orbit with it! --- Gerry :-)} London,Canada |

"I'm more curious how one hits a "buried stump" with a bush hog. If it's
buried, it's not an obstacle" Believe me, it's easy down here in La. Ant hill cover roots, partialy buried crossties and firewood chunks. Did you know that a small block Chevy head will stick up in an fireant hill to get hit by a mower blade? But it just low enough to clear the guard on the front of the mower. |
