Friends of my dad use an electric chainsaw to part up their deer. They run vegetable oil as the chain oil and zip the deer into quarters. They have an old ice freezer as their cooler, think of the freezers sitting outside the gas stations with the 10 lb bags of ice stacked in them - not the ones with the glass in the door. By skinning and quartering the deer they can get up to 8 deer in there. They also use their Willies jeep and a tennis ball to skin the deer.
First time I saw them in action I was stunned.
