I've got a John Deere L110 lawn tractor that I want to replace the mower
blades on. Today I drove it up onto a set of car ramps and reached up
under it to try to remove the two blades. All I managed to accomplish
today was refill the tires with air and remove some twine that had
wrapped itself tenaciously around the hub of the blade. As for loosening
the two end caps that actually hold the blades on: forget it. I couldn't
budge any of them.

Looking in the owner's manual says they're supposed to be torqued to 42
ft-lbs. Well, even using a piece of pipe as a cheat, I got nowhere. Are
these things reversed threaded? Is there a trick I don't know? I was
using a 1/2" socket wrench with a 15mm socket. Maybe I need to move up
to a bigger wrench?

I hate to pay for something I should be able to do myself.

You may have to remove the deck so you can adequately hold the jack shaft
and blade while you torque the bolts. Try a air wrench if you have one.
They should be standard counterclockwise to unscrew. Careful you don't
round off the corners of the hex bolts, then you will be in deep poo poo.
Put some grease on the threads when before you replace them so you don't
go through that again.


what he said.

Or, of course, a shot of spray lubricant
or
Heat with torch and then wrench off.
but not both (!)

One of those bound to work.

But, by now, that penetrant worked, right?
