Hoes dont have breaking sound

in survival minecraft 1.7.5 no hoe has breaking sound. they only dissappear from hand but no sound is made. i tried different computer too and bug still there. all other tools weapons still have breaking sound: swords, pickaxes, axes, shovels but hoes wont. i noticed it when creating massive field in my world i was holding right button and went over 5 blocks before i noticed i did not have hoe in my hand anymore. then i tested in other field and with cheats too for all types of hoes non has sound when breaking
