Question

Do i need special tools for?
what tools can i use to sharp the blades?

Answer 1

The best way to sharpen them is to use a bench grinder. The original blades aren't the best quality and can only be sharpened a time or two. New blades can be found at tons of hardware stores and are pretty inexpensive.... sometimes it is just as easy to buy new ones.

Answer 2

You'll need a socket wrench or regular wrench. You probably might also want a pipe to slip over the end of the wrench and something to hold the blades in place. You'll need the pipe for leverage since the nut has probably been on there for a while. Take notice to make sure you are turning the nut in the correct direction. The nut may be left-hand threaded to account for the turning of the blade so it doesn't come off. An air impact wrench may make the job a lot easier if you have one.

Actually the best thing you can use to sharpen the blades is a little grinding tool to fit on the end of your drill. It only costs about $4-$5. You don't need a grinding bench. After you grind the blades, hang them on a nail to see if the two sides are balanced.

Dremel makes an attachment that fits onto the end of your Dremel tool to sharpen lawn blades. It costs about $6. Just make sure you wear protective eyewear when you sharpen the blades. And make sure you wear thick leather gloves when you take off the blades. It is very easy to reach down and grab the blade without thinking with your hand if the blade happens to come free and you don't want to cut your hand if you accidentally do that.

The first time you take the deck off may be kind of hard, but after the first time or two it gets pretty easy. Just keep track of what pin goes with what and reverse the order when putting the deck back on.

Answer 3

a wrench or a good sized socket and ratchet. a 2x4 wedged in between the blade and deck to keep blade from turning. as far as sharpening them you will need a hand held grinder you can do it with a good file but it takes a while if your blades are bad.

Answer 4

I drive mine up on a 3-ft high ramp/deck, and use an impact driver and socket. Takes less than one minute to put the mower on the deck and remove both blades.
