Interesting. I had a similar problem with a 500 lb stove. I used my tractor to set it on the deck, and two inch PVC pipe for rollers. When the stove came off a roller, I just picked it up and moved it to the front again. The PVC pipe is non marring (just bevel the ends a little) and spreads the weight out so the hardwood floor was fine. Rolled it right up to the hearth. I used a piece of 2x4 as a lever to lift one side of the stove at at time, move the roller and set the stove on blocks. To lift the stove onto the 14 inch high hearth I called my friend Jack. He just picked it up all by himself and I just sort of guided it into position. I already had a roller on top of the hearth and when Jack set it down about half the stove was on the hearth, the rest was hanging out in thin air. I steadied the stove and just rolled it on back, then used the lever to remove the roller. Since I already had the scrap pipe and 2x4 it cost nothing and went very quick.
Oh, if you want to try this method yourself and want Jack's help his full name is Hydraulic Jack. Some call him by his nickname, Trolley Jack. I'll include a link with his contact info.
Another trick for rollers is a bucket of golf balls. The nice thing about using the balls is the heavy object will move in any direction. http://www.northerntool.com/shop/tools/ ... 4Aod_38A3w
