WAYS TO EXECUTE INVENTION

IN 1 and 2
schematically the machine according to the invention for sawing firewood is shown.

On the frame ( 28 ) on the side of the rocker ( 29 ) a wheel with an axle is attached to the left and right. On the opposite side of the frame ( 28 ) is an extendable stand (left and right) 14 ) appropriate.

On the ascending strut of the frame ( 28 ) is at the upper end of the drive shaft ( 23 ) of the saw blades ( 21 ) with the bearing blocks ( 16 ) screwed. On the drive shaft ( 23 ) is the V-belt pulley ( 15 ) attached.

At the lower end of the ascending strut of the frame ( 28 ) is the drive motor ( 18 ) with screws. On the drive shaft of the engine ( 18 ) is the V-belt pulley ( 19 ). The power transmission from the engine ( 18 ) to the drive shaft ( 23 ) with the V-belt ( 17 ) transfer.
