Rotary hoes are a useful cultivation tool for your garden. They are great for removing weeds and loosening compacted soil. They encourage crop emergence and reduce soil crusting without causing soil compaction.
A rotary hoe can help turn a tedious task into a not so tedious task by mechanising the job and reducing time and effort.
A rotary hoe can turn and loosen the soil better than a shovel and fork, much like mixing a cake in a bowl with an electric whisk is better than a spoon by hand.
