Chiropractor's Tractor

I get paid driving a farm tractor with sideline job as chiropractor; I massage, soothe muscular pains, move circulation through your veins; though never trained in orthopedics, I've got some real skills like the medics; strained tendons or twisted ligaments, come, just suit yourselves, my compliments; I rub and press, and even squeeze your bodies, limbs, extremities; be yours the size of whales or eels, your aches, your ills this masseur heals; the contours of your anatomy are easy topographies for me; I've learned skills of a land surveyor from years of driving a farm tractor.
