Mine might be slight overkill for what I do as there is a smaller model, but here was my situation....I used to try to sharpen them with a grinder, but to be honest they came out terrible. So being that when I started out I only had a few blades and I only cut a few lawns, it was relatively inexpensive to have them sharpened at my mower dealer. Well after getting a few more sets of blades for each mower and a couple new mowers, I was spending a ridiculous amount of money getting them sharpened in addition to the hassle of dropping them off and picking them up as well as gas and waiting for them to be done on their schedule. So I cannot say enough about how much money, time, and energy this thing has saved me as well as peace of mind that there will be less wear on my machine because I know they are balanced correctly as well as being perfectly sharpened. My suggestion-as soon as the cost is justified, get one of these!

Yepper!! And MY plan is to be able to justify the cost NEXT SEASON!!
And it is a hassle. I'm using a grinder now and it's a pain in the butt. I'd love to have a fresh set just ready and waiting. I'll have to look into the less expensive model.

Hey All! Grassman's Dad here...
I ordered a new Magna-Matic at the GIE Expo this year. The 8000 model to be exact.
They had a show special on part of it, so I got the stand, light, rolling wheel kit, extra wheels, balancer and of course the main unit. I assembled it yesterday. It's pretty quiet compared to the RBG. My RBG has served us quite well, and still works great, but I wanted to upgrade. The RBG is now for sale locally, too heavy to ship.
The Magna-Matic has an outlet for a vac attachment. My vac hose and the outlet are definitely no the same size. Does anyone here know a good place to find a rubber boot?? I am not sure what to look for, but it would be much like a PVC reducer, only rubber so I can put a hose clamp on it to secure it.
Thanks!

Hello All,
Ok in this post I'm going to go through and answer all of DLAWNS questions.

1. The first question you asked talked about the "end of the blade." My
guess is you are talking about the TIP or cutting tooth of the blade. The end or pointed part of the blade is the primary cutting area on the blade, this is evident when you look at a used blade the tip has become rounded, and metal has actually worn away and the dimension of the blade has changed. Lawn mower blades are measured diagonally because the TIPS actually stick out and make-up the full diameter of the blade. The TIPS of the blade (and the first 1-2 inches) do 95% of the cutting work. A dull lawn mower blade is defined as a blade that has rounded TIPS. So when sharpening a blade you want to grind back the face of the cutting edge to bring the TIP out again, or grind back until the TIP is “square-looking.” When you are going back and forth against the grinding wheel, take care to back-off your pressure into the grinding wheel so you don’t slip across the face of the wheel and ruin the TIP you just ground.

2. The second question was about a rough edge, this is the burr that is created when you have to grind back so much material. This rough edge or burr is just a by-product of grinding a lot of material – you have done nothing wrong. Simply take a hand file and with one or two passes with the file take the burr off. This is mainly done for safety so you don’t cut yourself.

3. Where should you start sharpening? This is preferential; you can start any place on the blade you like. I recommend that when servicing a blade to first clean it – inspect for fractures and see if it is worth re-sharpening (bent etc). Next sharpen both tips of the blade so they are square again. Next check the balance, if one side is out-of-balance use more of the interior of the cutting edge for the balance correct, and stay away from the nice TIPS you just ground.

4. How do I know when a blade is worn out? When looking at a new blade, look at the “underside” or “land-side” of the blade. Note the distance from the tip to where the bend of the lift begins. This width of material is your “LIFE-of-the-blade.” This is why you should try and remove as little steel as possible near the TIP – this will prolong the life of the blade.

5. When should I change my grinding wheel? The simple answer is when it is all gone. Unlike some of our competitors we allow adjustment to use the grinding wheel up to the blotter (circle paper label). Some people like to flip the wheel around on the MAG-9000 due to the self-dressed angle – which is perfectly fine to do if you want use every last bit of the wheel up.

Well let me know if I covered everything

Hello All,

Ok above there was some mention of using face masks so as not to breath in any grinding dust.

This is always a good idea to wear while grinding. While a shop-vac will get a great majority of the dust and debris there will still be a bit of dust in the air.

We're currently working on our own vac/air cleaner design for our sharpeners to provide a 3 stage filtering system to shoot for a 95% air cleaning level so that you would not absolutely wear a mask.

The last post from br549oicu8 - just for your information - Magna-Matic sharpeners are designed for a 2.5" diameter hose - if you bought a 5 HP or greater shop-vac that should be the hose size, and it should fit right in. If you have a Craftsman vac or a smaller HP vac then your hose will be too small. The connection for the sharpener is a 2.5" inside diameter of the grit guard - so 2.5" outside diameter for the hose you'll use..

Thank you,

You covered everything.......Thank you so much for all of the great information! The first question though was the "end of the blade" I meant the farthest end of the blade from the center hole. I'll take a picture one of these days as it is very hard to explain what I mean. I appreciate all the time and effort helping me out. Do I order new wheels and a new table right from the website? Also I would love some info on the vac system that you guys are working on once it becomes available. Thanks again Gerd!

good answers, sorry i forgot about this thread, should have subscribed.

anyways, i am a bit confused to the whole squaring the tip of the blade every time.

is a way to reduce the amount of curving at the tip of the blade? got a pic to demonstrate the method of sharpening you described.
