Can someone tell me what the size of the nut that secure sthe blades on a John Deere LA 165 Lawn Tractor.

[Dave Riley]

Having trouble removing the blades of my lawn tractor at my summer place. Want to buy a socket but don't know the size

[Ed Pawlowski]

Use an adjustable, but make sure it is a metric one.

[Dean Hoffman]

Entering the part number GX21694 brought up this page: Use the chart on the left: A 5/8" nut generally means a 15/16" socket will fit. Note that it's a fine thread lock nut. Those aren't all that common in my little world. Why not get a full socket/wrench set?

[Ralph Mowery]

Does anyone take time to look in the manual or if they do not have one, to search for one ?

Installing Mower Blades

1. Position mower blade (C) with the cutting edge towards the ground.
2. Align the splined center hole in the blade with the splined spindle shaft (D) and put the blade onto the mower spindle shaft.
3. Install washer, with cupped side towards blade, and install nut to secure blade onto splined spindle shaft.
4. Block mower blade with a piece of wood to prevent spinning and tighten nut: ? Using 15/16 in. socket, tighten 5/8 in. blade nut to 88 N?m (65 lb- ft).

If you can not read letters and only see numbers:

16/16 inch socket.

Are you sure, my inch crescent wrench fits? Maybe that's the difference between an adjustable wrench and a crescent wrench.

[Gordon Shumway]

A tape measure would be a good place to start.

Crescent is manufacture name.

I know. It was a joke.

Woooooooosh.

After wrestling with stubborn blade bolts for years, I finally bought a 3/4 drive 6-point impact socket and a 38" breaker bar.

[Retired]

Amen on the breaker bar. We use a 30" piece of pipe on a 1/2" drive

15MM socket. That and lots of PB Blaster !! John Deere L111 mower deck has 2 bolts (not nuts) per blade

[Ralph Mowery]

Too much trouble. Just use an impact wrench on them.

I do not even have to block the blades to keep them from turning.

[Suna Muhnitch]

Yup, one of these days I'm goona get me one. ;-)

[Ed Pawlowski]

Everything is going metric. I recently added some new tools, like a metric hammer and saw.

Curious... If it's adjustable, why does it need to be metric? Or are you just kidding?

Oh, I can see the need for a metric hammer. How else would one hammer a metric nail?
