getting blade off

My Snapper LT-200 42" blades are brutal to remove because the pulley spindle turns (crankily) with the blade bolt. Yes I'm using a wood block to stop the blade. Only solution (still near-impossible) is two extra long socket wrenches, clumsy and painful with the deck on edge between my legs. There must be an easier way. Am I missing something?

Any chance of using an impact wrench, like the ones used to remove lug nuts.

Are you using a Breaker Bar? Extended with a piece of pipe ?

Is there Lock-Tite on the threads? Maybe a little heat from a torch would help. I just removed the impeller from a snow blower using a little help from a propane torch when my Gear Puller alone couldn't do it alone.

Make sure you only use 6 Point Sockets; 12 Points will begin to round off the blots and make it even harder next time . . . . if there is a next time.

If they are beginning to round off, you may want to consider replacing them with a higher grade . . . . like a Grade 5 or Grade 8 if they're available.

Like Larry, I usually use an impact wrench. Have you tried using a breaker bar/socket for extra leverage?

So, you're spindle is turning even though you have the blade blocked? I wonder if your bolt is corroding/rusting in the spindle. Maybe coat the bolt threads with grease when you re-install the blade to make it easier to remove next time.

I agree with the impact suggestion. Even just an electric impact.

Blade is blocked With wood. Not trying to remove spindle nut. No pipe but using two long (18"?) 1/2" socket wrenches. Problem is that the spindle turns before I get enough torque to loosen the blade nut. Spindle nut is recessed in pulley so I can't just hang a vise-grip there to hold spindle nut.

Took deck to shop, came off easily with impact wrench with just fingers holding spindle pulley. I'm buying one for sure.

How would I determine safe load and necessary hardware to hoist from ceiling of my garage with 2x4 joists 24" OC?

Your garage ceiling isn't made for lifting if it is trusses as I suspect with 2x4 bottom chord. Second best would be an engine lift or a floor jack to get it high enough to work on.

Block blade and use a 6 point box end wrench. 1 sharp blow with a hammer will take it off.

Try 20-30 blows after PB Blaster Penetrating Catalyst on overnight. No go. Reaching the torque of the spindle foiled me every time. She's good now.

That was a heck of a 30 minute quickie task - try a good part of two days including the trip to the shop today. Probably didn't help that the blades hadn't been changed in 3 years . . .

Goin with the air tool next time.

As Larry said, you can't use a truss that way. I have a doubled up 2x12 in my barn that I occasionally use for lifting. If it's a single car garage you could double up 2xs in the ceiling joist bay provided you can adequately support them on both ends. The size of the 2xs and length of unsupported span determine how much load they can support. I've known guys that have beefed up old swing sets to use as engine pullers, one even made one out of wood

When I helped my son work on his riding mower we just stood it up on the rear tires and then used notched 2x4s to supported the front.

That's what I like about my Kubota ZTR. There is an internal jack that rotates the front axle to vertical allowing safe maintenance beneath. Not as nifty as an Indy car jack set up, but it works.

Sister a 2x8 to one of your trusses then put a temporary post under each end of it this should lift any mower.
