I've never removed my entire deck for any reason but I've though about removing my deck (4 bolts) to change blades and check bearings and pulleys on the deck itself. I just wondered how long it takes and if it would make blade changes easier.

Dude get a cordless impact and a small floor jack. You have a 5 minute or less job that you are talking about making an hour or more job out of. We change blades on Tiger Cats some times 2 and 3 times a day when we are running them flat out in Bahia Grass. It is literally a 5 minute job done that way.
bertsmobile,
The bolts are 5/8 x 11 x 9 1/2" long. They pass thru the a washer, blade, spacer, the spindle and are held in place with a nut on top torqued to 75 FTLBs.
The machine has to be jacked up enough to allow the bolts to drop out of the spindles.
jekjr does this several times a day times three machines, I think that he has the procedure down pat!:laughing:
I use an impact gun to remove the blades and reinstall them.
I also added a hoist in my garage and just let the hook down, with the aid of a nylon strap or two on the front and lift it up in the air. I added hooks to the rear and lift the rear end up with the chains on the back half. I could lift it high enough that you could work underneath sitting on a low stool.
I try and work smarter now as I get older. Car jacks and hand tools are too much work.
I recently had a hydo belt issue so I will get it up on the rear instead of me getting under. I'm getting old and somewhat inflexible.
When I do the blades I don't have a trailer to get it up so I use a pair of straps and lift the front 30 inches off the ground. Then I work on my knees reaching underneath. Only the center blade is hard to reach, that's why I lift it like I do. It took me 5 minutes to do the blade swap. More time to pressurize the air compressor than to do the job.
The impact gun and hoist are extremely fast to use, my body is slow to crawl around. :laughing:

I've already done it just inspect all the pulleys and bearings not for ease of blade change. I do think it should be done occasionally just to keep things tip top but all the other times i just use a breaker bar but I may invest in a 1/2 drive cordless impact in the near future.
Hydro belts are a pain. I have changed several in the field. ;P They are about like putting a cat in a quart jar.
It's weird 3 weeks ago I had a branch flip up and remove my hydro belt. That was a million to 1 chance of ever doing that.
I seen the 3/4" branch laying in the field, I said screw it as I need to pull these blades and get ready for leave season anyway, so I just went over it slow. The machine lost all power to the wheels. I shut it down and seen the belt underneath.
I towed it back with the tractor and positioned it under the hook. I lifted it up expecting to see a bad belt or bad pulley. Nothing. Everything looked in good condition. I reinstalled the belt and its been fine since. Weird, a million to one chance to flip that off by a branch. Lol
Heck that belt is tucked up there a good foot or more!
I bought one of those cheap Harbor Freight hoists and it hangs from the trusses in my garage. I use a nylon strap and it lifts my commercial TORO Z plenty high. I have several sets of blades so I just swap them out and when I have enough I sharpen the whole stack.
A couple of weeks ago I bought the Ferris IS 3200 and it weighs 1,500 pounds, a good 500 pounds more than my TORO. I don't know if my trusses will take more abuse.:laughing:
Mine is a 1300 LB harbor freight hoist. (I think). It's rated for more than the machine weighs so I should be fine. What I didn't like was it really winds the cable quick, so I hooked the hook to it's self and now it pulls on 2 cables. It's cable is stronger this way with an added bonus of winding a little slower.
In CT lately we get a lot of snow. If anyone knows about snow it gets quite heavy. I figure there are perhaps thousands of pounds on my garage roof in the winter. It should lift a zero turn safely without fear of bringing the building down.
I did reinforce all the rafters with wood and bolts, plus I added a 2" bar going end to end that the hoist is connected too. I'm sure I could double the weigh I pick up without any fear of the roof giving out.
One thing for sure, I love these hoists! It sure beats using floor jacks.
