Injuries and Fatalities
Even with the beneficial engineering advances leading to 
general improvement in safety and decreased fatalities, 
agriculture continues to rank in the top three most 
dangerous occupations into the 21st century.  Minnesota 
averages 31 deaths from agricultural work annually.  The 
financial impact of agricultural injuries is high, averaging 
$2,347 per farm nationally.  The leading causes of fatal 
and nonfatal injuries caused by machines include: 

     Motor vehicle accidents (farm machinery on roads)
     Tractors-roll-overs and run-overs
     Power take-off (PTO)
     Rotating shafts
     Grain augers
     Combine harvesting heads
     Balers
     Front end loaders
     Chain saws

Men are more likely to have an injury related to mechanical 
causes, while women are more likely to have animal-related 
injuries.  Animal injuries are more likely to be non-fatal. 
The major cause of mechanical fatal injuries involve tractors,
with rollovers the primary factor.  The majority of farms have 
operative older tractors without the rollover protective 
structures (ROPS), cabins, and seat belts, found on tractors built 
after the mid 1970’s.  

Severe injuries can occur from becoming entangled in moving 
parts such as power-take off (PTO) units, rotating shafts, 
corn and soybean combine harvesting heads.  These parts 
rotate at high speeds and can kill, amputate, or mangle body 
parts if they are not maintained.

PTOs operate by the tractor power. They are routinely greater than 100 hp and rotate at 540-1000 RPM (9-17 feet per second). Harvesting heads run at approximately at 7 feet per second. It takes at least a second for the reflex to travel from the brain to the hand to drop an object or withdraw. This will pull an arm or leg into a chain or wrap around a moving shaft/PTO before a person can react, leading to death or severe injury.
