I have this phrase and the context is the farming:
I need somebody... who, during planting time and harvest season will finish his 40-hour week by Tuesday noon and then, paining from tractor back, put in another 72 hours.
I do not understand paining from tractor back, what does it mean? Is it referred to the rear part of the tractor? Or is it referred to the back pain of the driver of the tractor due to his tough job?
