Find a level area, preferably on a concrete surface. Better if it's in the shaded area (more on that later)
There are two bolts at the bottom of the loader masts (where it mounts to the tractor frame). Loosen, but don't remove those bolts. That's the "wedge" locations.
Unhook the Latches (the levers you refer to) by raising them up, pulling toward you, then locking them down in the unlatched position. You'll see the two narrower sections of the latch rods. If fact, before you unlatch, note how they are located in a key shaped hole in the loader frame.
Once unlatched, pull your joystick back. The loader will rise out of the frame. DO THIS SLOWLY AT LOW RPM!!! You want to just clear the height of the front tires.
Once the loader frame is clear, back out SLOWLY! Just enough to disconnect the four hydraulic connections.
Stop the tractor and turn the engine OFF. Jiggle the joystick sideways to relieve the hydraulic pressure. Get off the tractor and disconnect the hoses by sliding the FEMALE quick disconnect fitting away from the male fitting. BEFORE YOU DO THIS, make sure the color coded plastic rings are on both the tractor side of the hose AND the loader side. That's the only way to identify which hose goes where. Your loader manual will also describe this. If those color coded rings are not there, use those multi-colored wire ties or something of that nature.
Once everything is disconnected, back the tractor away from the loader and operate as you need to.
The first time you do this, it'll take 10-15 minutes because you're nervous. After a few times, it's be a 2 minute operation.
IF YOU DO NOT FEEL COMFORTABLE FOLLOWING THESE INSTRUCTIONS, LEAVE THE LOADER ON UNTIL YOU GET THOSE MANUALS. Operating the tractor while mowing isn't that difficult...just must watch where the loader front end is.
I normally remove my loader for mowing, but I have mowed with it installed.
Now, about the shade... If the (uninstalled) loader is setting in the sun, the heat (from the sun) may cause the hydraulic fluid to expand. This can make it a bit more difficult to reconnect those quick disconnect hoses.
Hope this helps you...
