Car ramps should work. Just something to make it easier to get under the mower. May need to find something to keep the blades from turning when loosening them. 2 by 4 or something to jam the blade, if you can't hold it for removal.

Car ramps get in the way.
The deck takes less then 2 mins to remove.
I just take my deck off saves so much time and don't have to lay on the ground.
I have used a come along from a rafter or tree.
When I have the deck off I spray some lube on all moving parts on the deck and mower.
