NEW VINEYARD — A young boy whose leg was severed in a bucket loader accident on Monday has been removed from a ventilator that was helping him breathe, but remains in the intensive care unit at Boston Children’s Hospital, according to a family friend.

Adam Mattson, 4, of New Vineyard, had his right leg severed and left leg seriously injured when the bucket of a loader lost hydraulic pressure and came down on his legs. The accident occurred while he was with his grandfather at a family gravel pit off Anson Valley Road in New Vineyard. His grandfather Sam Kennedy did not realize that Adam had gotten partially under the bucket.

“Adam is doing great,” family friend Jessica Harris, of New Sharon, wrote on Facebook.

Adam is sedated to allow him time to heal, she wrote.

The boy has been talking with his grandmother and asking when they are going grocery shopping.

Adam lives with his grandmother Kim Mattson and Kennedy, who are his legal guardians. Adam calls them Mammy and Papa.

“His right side is healing wonderfully and the left leg’s pulse is getting stronger each day,” Harris wrote.

Adam, who attends pre-kindergarten at Mallett School in Farmington, faces more surgeries in the future.

Harris said she is grateful for the support the family has received. As of Friday morning, $4,525 in donations had been to a gofundme page Harris set up following the accident. Donation containers are also set up in The Roost on Main Street in Farmington, Our Village Market on Route 27 in New Vineyard and Bouncing Baby Boutique on Oakes Street in West Farmington.
