We have a hangar full of airplanes including a Cirrus and a C182 RG at our local airport.  All are moved quickly with an old recycled ride-on lawnmower.  The  secret: a VERY long tow bar (think 10 feet plus) made of 3/4 inch square steel tubing with a yoke that is pulled apart to engage the nose wheel, and then released to close into position.  The tow bar is then connected to the lawnmower. 

 

The long tow bar makes backing the aircraft into  position very easy because the reaction to any misalignment is slow enough to be easy to correct.  With a little practice I have watched as they wheel an airplane out, then the second one, then put the first one back including a sharp turn to angle it against the side wall.  It is a thing of beauty.  But it takes a LONG  tow bar.
