Upgrade NowThat's why my decks last so long!Fertilizer is the biggest problem with Decks rotting
I have the hand crank one. I’m going to have to upgrade to the hydraulic one soon. Getting old.Doug,
I bought one of those too. I had no plans to. I didn’t even know they existed, but I happened upon one for under $12, and I “took a chance”.
No, You just need to file out the nicks and make shure the edge is good... Also if you build the blade edge with weld it is really gonna make it hard to balance them again.. Just normal sharpening and your blades should last for many years...I thought you were supposed to go over edge of blade with a fine file once to get the knife edge off it. So it does not dull fast.
Any welding on mower blades will change the structure of the molecules. Blades will break at the edge of the heat zone.not trying to bust any ones ideas but...I've burned on 100s of lbs of hard surface rod on loader buckets,crane buckets ,dozer blades, etc.....I personally am not good enough to get close to a fine cutting edge without distorting the edge and when you were done it would be necessary to grind a cutting edge back on.Not to mention what the heat would do to the rest of the blade,as in change the temper.If you have ever tried to drill good quality blades you'll find they are quite hard already.(I've been known to make knife blades from them) I use a 4" grinder and move it continously to keep from burning a spot which will change the temper....If one doesn't mow rocks and sticks they hold up very well. to each his own......
[/QUOTE]When you take medium carbon steel and temper it to 35-48 rockwell you are case hardening it.. If you need a example of the process, Go to Wikipedia and look up case hardening.. [ QUOTE="gary noblit, post: 232795, member: 15311"]
trying to be better informed I chased the subject of "what are mower blades made of ?"Yep, spent an hr reading everything I could find ..The consensus of opinion is good blades are made from medium carbon steel tempered to rc from 35 to 48...cheaps are made of low carbon..none are made of high carbon because of likely breaking issue if they hit any thing....none that I found were case hardened.... don't take my word for it go looking your self...
