[TheForge] Lawn Mower Blade

[David E. Smucker]

I have had a Gravely for about 15 years now -- still has the original blade 
on it.  I don't use it near as much as I use to but it had a least 10 years 
of heavy use.  Blades are 5160, and heavy like a Bush Hog blade.  You can 
forge out the cutting edge and then grind, no need to heat treat.  This is 
done all of the time with Bush Hog blades.  After working on you blade you 
should balance.  Only problem I have had on the Gravely is breaking some 
teeth of the bevel gear set that drive the blade out of the main gear box. 
I haven't replaced them yet but know I should so it is on my to do list. 
Gravely keeps parts for units that go back many many years -- but of course 
they are never cheap.  (All of this is based on the assumption that you 
Gravely is of the type with the cutting deck out front of the gear box, 
wheels and engine.  This is the original type of Gravely, they also make 
other designs too.)
