A 77-year-old southwest Minnesota man died Thursday afternoon after an accident at a rural Sleepy Eye farm.

KARE 11 reports Donald George Richert was operating a skid loader on his property when he got out to move something into a nearby burn pit. The machine then moved forward and pinned Richert's left leg under the front end, trapping him in the pit.

When first responders arrived around 4 p.m., Richert had suffered extensive burns on majority of his body. He was pronounced dead at the scene.

KSTP said Richert's property is in Prairieville Township, about 5 miles outside Sleepy Eye.

The Mankato Free Press reports two volunteer firefighters who had been working in the area discovered Richert.
