I love operating heavy machinery as long as I don't have to get out/off the heavy machinery.
If I have to get off to fix it when it breaks then I'm unhappy.
Using an airconditioned tractor for literally anything, fun. Unjamming the fucking hay bailer when it's over 100F and 95% humidity and there's dust everywhere, not fun.
For real, give me the ol' "Hey, bud?" first and then when it's clear I'm paying attention, then ask.
