Short Final: Switching To Guns

I heard the following around my home airport:

Cessna 1234M: “Cessna N1234M, four miles northeast for landing with Echo. Full stop.”

Tower: “34M turn right base. Cleared to land 25R.”

A few moments later as the Cessna was on short final:

Tower: “34M, be aware tractor mowing between 25R and 25L.”

Cessna 1234M: “Roger. Too close for missiles. Switching to guns.”
