This is intended, you need a water source nearby:

Changed the way hoes work
If used on dirt and water is nearby, the dirt will be tilled as normal
If used on grass and no water nearby turns grass to dirt and creates a random seed
Chance of seed depends on difficulty (10-40% per try, configurable)
Can be disabled in the config with 'modifyHoeUse'

ok thanks for that
