Changing/Sharpening Blades on 48 Exmark Metro

Its about time for me to sharpen/change the blades on my Exmark Metro 48 mower. I propped it up, was able to get to it, but I just could not get the damn things off. I must say, though, I am not the best with my hands. Do I need a special tool? Is it just really hard to do? Any advice would be appreciated.

The first time this season (spring, summer, fall) ?

I heard if you use sharpening fluid in the spindles though, you don't have to sharpen them at all.

Sorry Pizpoppa.......couldn't resist. Seriously....

I do it the old fashioned way...I have a 2 foot breaker bar so my hands stay clear of the sharp parts and a crescent on top.

It is a rather simple process you loosen the bolts on the top and bottem of the spindle simultaneosly. Blades should be sharpened once a week at the very least, unless you only mow a lawn or two a week.. Hope this isn't the first time this year.

Two solutions buy impact wrench or goto your friendly neighborhood gas station and ask the mecanic to pop them of when you fill up your tank. I got a used mower with siezed up bolts and that was the only way to get them off.

I also own a 48 inch Metro, to get the blades off you need a rather large wrench to get enough torque to loosen them, once you got them loose, the bolt just spins off. Put a little muscle into it along with a good long handle. Good luck.

If a wrench, breaker bar or impact wrench won't do it use a torch and heat up the top nut then wrench it of, that should work. I've had to do that a couple times when someones hit something and bent a blade and the bolt got tightened up so bad I couldn't even get it of with a impact wrench.

I had the same problem on my Exmark Viing hydro until I bought an air compressor and impact wrench. I did it the hard way for a yr or so and then cut my thumb pretty bad. That was enough for me. It's a piece of cake now. When you sharpen everyday, I can't imagine removing blades the old manual way.

AIR TOOLS

an air impact wrench is a landscpers best friend, makes scraped knuckles and breaker bars a thing of the past. I wouldnt trade my air set-up for anything, it has saved me so much time on equipment maintnace. Deffinatly worth the investment.
