Craftsman 917.256600 Help Blades & Steering

Greetings to all from the North Jersey Shore.

I recently purchased this older Craftsman Garden tractor. 15.5 Kohler & a 46" cut.
I used it to cut about 3 acres and overall its OK.

The trans on my JD LT180 is going and I needed something PDQ. Nice thing those non serviceable trannies :-/

I took the blades off to sharpen and found an odd [at least to me] configuration. The original blades are #'d 900811 and around 15" long. They have a very different shape, i.e. not straight across

My usual repair shop strongly suggested that I get a new set with just a "straight" edge...something that can be sharpened easily.

What kind of blades are these [how does someone sharpen them??] and what [if anything] could I / could I replace them with.

Oh, they have a "star" center hole.

I'll be back another time to learn about the steering wheel issues I am having.

Thanks for your input

They're very common "3 in 1" blades. A lot of riders have em. Very easily sharpened. Good all around blades if ya wanna mulch, nope changed my mind, wanna side discharge, naw, I think I'll bag. Hence the 3 in 1.

The flat blades are good for baggin or dischargin, the higher the wing, the more lift ya get.
They make a sand blade with very little lift if ya got that problem.

At any rate, be sure you keep the blade's star engaged in the spindle hub lugs when ya tighten them up. I replace several spindles each season where people failed to do that and just slammed the blade bolt home. Creates quite the mushroom effect on the spindle lugs!

Dear Mr. Fish...or do I call you Big? Thanks for the input.

My repair shop did not want to mess with these blades.

I do not [deliberately] mulch...have always had straight blades.

Cut 3 lawns [family] about 3 acres total.

My JD LT180 48" is dying a slow death with a deteriorating TuffTorq trans so I got the Craftsman in a panic.

I've been known to do a "decent" job sharpening my own blades but these mulchers had me puzzled.

Is there any downside to getting "straight" blades and if not what should I get?

Thank you.

I thought I 'splained it pretty well.
You can always google a blade comparison.












That would be the highly experienced Mr. Fish, thank you very much!



Or whatever comes to mind,right?

Sharpen what you have yourself. You'll be fine. Go to Sears to get new ones.

Though not H.F. junk except for the wheels.

Absolutely no burning with the carbide burr, and I use the right angle/cut-off wheel setup for sharpenin' dam near everything including hedge clipper blades.
One of the advantages of the cut-off wheel setup is you can't really put enough pressure on it to cause burning, but it will remove metal quickly.

Where's the Momoneymatic crowd? One set of blades will justify it for the perfect edge that will turn any lawn into a groomed fairway with just one cut.
