Question:
Am I allowed to use a leaf blower and mulcher on Chol Hamoed? I am aware that I am not allowed to mow or hedge trim.
Answer:
Taking care of a lawn is not tzorech hamoed, (a Yom Tov need) and therefore should not be done on Chol Hamoed. If there may be a monetary loss involved, then resubmit the question with the details.
Have a good Yom Tov
