Sharpening blades

Hi all,
What do the mower shops use to sharpen their mower blades? Do they just use a bench grinder? I have a professional 10" bench grinder but I cant seem to sharpen them as nice as the pro's do. Do I just need practice or is there a special tool? Thanks!

Alpine - there's no special tool - but experience and a steady hand helps. The shop gets them sharpened by using a dedicated rotary blade grinder. It's a lot like a bench grinder BUT the wheel RPM are lower. Thus, the metal does heat up and lose temper as easy when you sharpen. These grinders are about $300 for the basic model - but well worth it. We purchased one last year (after using a bench grinder for years) - what a difference!! The blades stay sharper much longer - up to 2-3 times longer!

My local JD dealer uses a large hand held grinder. I bought a dedicated blade grinder last year that does a great job. - RBG #218

dremel sharp?

Does anyone know if a Dremel tool will do a good job with blades? I have a bench grinder but am not happy with the results.

I'd stick to the bench grinder before I'd use a Dremel.

I came up with a unique idea with sharpening blades. I bought a converter that converts your dc battery power into ac power. I have a small grinder and I just take the blade off and plug in my grinder to the converter and sharpen my blades right on the job sight. Saves money and gas and time.

I have used a dremel for sharping gas hedge trimmer blades and it has worked very well for me. Right now thinking of a MAGNA-MATIC ,and getting away from the bench grinder for lawn mower blades, Trying to justify the cost. Any openions on this sharpener would be appricated, I know of other machines at less cost, Just needed some openions. Thank you ,Scott.

fireball

i bought a fireball grinder 5 yrs ago.....500 buck including shipping.....well worth it, heavy duty motor, reverse directions and a snap to use, just shove the blade in and out 5 or so times and its done.....btw we sharpen blades every day or atleast change them every day. we have more than one set.......sharp blades are ESSENTIAL!!!!!!!! for the grass and the mower.

I have a multi use sharpening system. It is a Tormek( not sure of spelling) It is designed to sharpen about anything(knives, chisels, axes etc. I has a 10" inch grinding stone that revolves in a bath of water and a fixed arm that you use jigs on to hold proper angle. I removes Very little metal at a time so would be good for touch ups or final sharpening only. I used it to cure a badly nicked blade once and it took a long time and since the grinding wheel is sacrificial you probably would want something else for rough work. It puts a SUPER edge on. I am sure that a grinder for lawn mower blades would be more practical for commercial use But it is a GREAAAAT tool for the shop if you like toys. It runs about $300.
