It ain't that hard driving a tractor all day.
I've heard driving a tractor too much will do that to ya.
Yeah, 8 hours on that big vibrator....
Should be more wimmins signing up to drive them things then. Especially at harvest time in E WA, them folks work from before dawn 'till way after sundown using lights. More like 13-15 hours.
Special 'attachment" on the seat pedestal and some gals might be begging for OT and mobile fueling so they don't have to shut down.
