The 300X is self-standing, but it doesn't require any additional stand parts to get it to stand by itself. The FEL 'removes itself' and all you have to do is get off the tractor to disconnect the 4 hyd hoses.
From the seat, you flip two latches on each side of the upright columns after lowering the 'bucket' all the way and slightly lifting the front wheels. Then after the latches are flipped, you 'raise' the FEL which actually lowers the frame that was attached to the front weight bar, down to the ground, afterwhich the rear contact points lift in the air. At that point the FEL is free of the tractor. You shut the tractor off, wiggle the joy stick to remove any oil pressure in the lines, dismount the tractor and remove the hoses at the quick disconnects.
About a 20-30 second job.
