State police said a plow driver was threatened with a gun while on the job in Bolton.
Troopers arrested Stephen Arnold, 59, at his home Thursday night.
They said Arnold had an ongoing dispute with the victim and pulled out a revolver while the victim was plowing a business.
Arnold pointed the gun at the victim and stated "I'll put you in the ground," troopers said.
The accused then drove away and returned a short time later when the victim was plowing a second business. Arnold pointed the gun at victim again and fled.
At a third business, the victim said he heard what sounded like a "pop" and believed Arnold had fired. That's when state police said the victim called them.
When they arrived at Arnold's home, they said they saw him run into the house. Arnold was then taken to the floor in his kitchen and arrested, troopers said.
State police found the firearm they said was used in the incident, along with several others.
Arnold was being held on a $20,000 surety bond and was due in court Friday.
