What is the most common cause of injuries when operating a tractor?
rollover incidents
The most common type of tractor accident is when a tractor rolls over. Tractors are top-heavy, which makes rollover incidents more likely to happen. They can additionally be caused by poor hitching, traveling up a steep incline, holes in the road or field, excessive speed when turning, or driving too close to ditches.
What is a PTO accident?
Power Take-Off injuries are very common on a farm. According to the National Agricultural Safety Database, most PTO accidents occur when clothing and/or limbs are entangled in the rotating PTO shaft. “Power Take Off” (PTO) is a term used to describe the process of transmitting power from one point to another.
How much play should a PTO shaft have?
First, there should be at least a one-third overlap between the shaft and the tube. If you’re using a slip sleeve, the overlap should be approximately 3 inches. If the shaft is too long, it will bottom out and create a conflict between the tractor and the shaft.
Should you grease your PTO shaft?
The PTO shaft should be greased regularly to keep the universal joints from failing and to stop the shaft from seizing. Failure to grease your shaft regularly or as outlined in the PTO shaft’s maintenance schedule could result in end thrust potentially destroying the implement’s gearbox.
What are the top 5 accident types in agricultural settings?
The 5 most common farming accidents include:
- Overturning Machinery. While tractors overturning over are the most common cause of death stemming from farming accidents, almost any type of machinery can rollover over given the right topography.
- Animal Injuries.
- Asphyxiation.
- Falls.
- Entanglements.
What causes the most deaths on a farm?

What danger can arise from the power take-off shaft of a tractor?

What happens to the shaft when it is in 1000 rpm?
When operated at full recommended speed, a PTO shaft will rotate clockwise at 540 revolutions per minute (rpm), which equals 9 revolutions per second, or at 1,000 rpm (16.7 revolutions per second). As shown in the Table 1, a 540 rpm shaft travels 7.1 feet per second, while a 1,000 rpm shaft turns 13.1 feet per second.
What is the important rule of power take-off in tractor?
Disengage the PTO and shut off the tractor before dismounting to clean, repair, service, or adjust machinery. Always walk around tractors and machinery instead of stepping over a rotating shaft. Always use the driveline recommended for your machine. Never switch drivelines among different machines.
