I just purchased a new RBG-121 blade grinder,they have bigger models. unfortunatly J.Thomas the place i purchased it from doesnt carry any other bg models right now. I wanted to know if this blade grinder will accomidate my needs throughout the years or is it the upgrade after two years model? I want to buy just one that will be good enough for any job. I have four mowers a two 60" one 52" and one 21". No bush mowers and dont plan on it. Would like to find our where i could order one and which model is the one to get. Thanks in advance for the replies.

bdemir: Its a little to late to decide if its right or not. I don't recall that modle from when I was looking but as long as it works for what you need it should be fine.With a bigger motor you can lean a little harder on each pass as compared to a small motor unit. Get your self a Ruby wheel or one of the new Blue wheels that reduce burning as you grind. Happy grinding..

bdemir:
The biggest difference between yours and the larger framed grinders are that you can sharpen a blade with a longer cutting edge. For instance yours may sharpen a blade with a six inch cutting edge and the medium frame will sharpen an eight inch edge and the large frame will sharpen 12" edge or something like that. Remember the first inch of the blade does 90% of the cutting.

Gene,
Thansk for the response. I was asking becuse i can take it back to where i purchased it from and buy the bigger model but the bigger model happens to be $600 and there is no medium models in stock so i thought that i could get it from somewhere else.

Mine is a 2181P I've had it about 5 years and it does a great job. Get you a shop vac or some kind of dust collection system, makes a world of difference. They also have a blue wheel out now that is supposed to be better than the ruby wheel. I'll try it next go round.

South Side, a blade grinder is a bench type grinder that is designed for sharpening blades. I use a 10" hand held for the rough cut of the blade and a 4.5" for the finish.

I'm not sure which brand you guys are talking about, but I assume the RBG stands for Rotary Blade Grinder. I went to the Lesco open house today and looked at their model and wasn't very impressed. I got a card from Brandlein Machine Co. in Indianapolis today that has one called a Fireball that does look like a good one. Does anyone have any experiance with them and know how much? If so, which model did you get? I emailed them for a dealer in my area so I can check them out. I noticed their website has no prices or dealers.

Eric: I have the Fireball 128,its rugged,works great. I wish it had an electric brake on it to stop faster when switching grinding directions.I got mine two years ago, around $630.00..They only sell from the factory direct

I've seen that lesco thing and it's junk. I looked at the fireballs as well they looked pretty nice but the RBG were the best in my opinion. Yes, RBG stands for rotory blade grinder which is manufactured by Wall Enterprises Inc. 1-800-354-5888

bdemir, I just ordered the 2181P RBG. It will sharpen 9 1/2 inches of the blade where yours will do 6 1/2 inches. The biggest model does 10 1/2 inches, so I figured the 218 was big enough. I ordered it out of AM Leonard in Ohio, free shipping and no tax and was $404.22 so that wasn't to bad compared to some of the others I saw.

Thanks for the good info guys. I broke my shoulder when I broke my back the second time and it has no cartilidge left in it and gets very painful operating that 10" hand grinder. I hope this helps me out.

PLS, I noticed you mentioned the blue wheel, that is a Ceramic Wheel and is supposed to be better. The one I ordered has it on it, so I will let you know how it does. About how long does the Ruby Wheel last. I see you can keep adjusting them until it is almost all gone, so it looks like we can get our moneys worth out of them. The Ceramic Wheel that comes with it, lists for $43.54, about $8 more than the Ruby Wheel. I appreciate your suggestions in the above posts. I just wanted to let you know what I had found out. Thanks again guys.

Eric, I don't know how long they last, I'm still on my first one, and I've had it about four or five years. You will like that grinder, make sure you get a grit box for it, and that wheel dresser is kinda pricey but it works great and is probably worth the money. You can really tell a difference after you dress it off. Also hook you up some kind of dust collection system, I use a 4 hp shop vac with a fine dust filter bag. I also found that it's alot easier on the back if you put it on a tall stand, mine is about elbow high. Good Luck!

One thing that I learned about blade grinders is that it is very difficult to keep adjusting the angle for each blade.

I finally bit the bullet, and ground all my blades to the same angle, and now sharpenings only take a few passes.

I will now sharpen a new blade before I ever mount it on a mower. I like having the sonsistency that I now have.

I have the new Lesco model. It is very similar to a regular bench grinder, but has a much better table, and also rotates in the opposite direction.

Once you get the hang of it, and get all your blades christened to your angle, it works fine. It took me some time to learn the machine.

Strange thing about my Lesco dealer is, they don't use a Lesco blade sharpener for sharpening blades. They have a RBG blade sharpener for that and it's only $50 more. My question is, I wonder why they don't stock the better sharpener if they won't even use the one they sell.

For you guys that are wondering about the RBG or Fireball sharpeners, the whole motor and wheel raises and lowers with a crank to set the blade angle adjustment and the blade lays on a flat table. Once you get your angle set, you can tighten it down in that spot to have consistant angles. The motor will run both directions for left or right hand blades. The link to see it is <a href="http://www.amleo.com/help-desk/item.php?bg218">Blade Sharpener.</a>
