Homemade shovel modifications

Two times per year my father and I must dig the garden
(300 sq.m.) we keep for planting.
It reoccurs every spring and autumn. And for this we use an ordinary shovel.
For me, this process has always been boring and tedious. Those who engaged in such exercise know it creates stress on your back. I searched the Internet and found the solution. Together with my father we created 2 modifications of digging shovel, that improves the digging process and goes easy on your back.

I share with you the two versions of shovels in testing.
Huge thanks little goat for free participation in the shooting ))
