CALEB CHECKING CONTROL PANEL CONNECTIONS ON ‘NEW’ WOOD PRAIRIE ‘LOCKWOOD’ POTATO HARVESTER. Sitting in the cab of our 135-horsepower ‘White 135’ Diesel tractor, Caleb troubleshoots a connection on the intricate two-row ‘Lockwood 4620 Aire Potato Harvester’ control panel.
For a late 1990s machine, this Lockwood has relatively low hours. It’s first two Aroostook County Potato farmer-owners both kept this Harvester in reserve as a backup should the Fall turn wet and nasty.
Fred, the third owner and the retiring seed farmer we bought the machine from, was a careful and meticulous grower who only grew a moderate acreage of Potatoes. So, the machine is in good shape.
In exchange for the Lockwood’s added operational complication, as compared to our much simpler one-row Finnish ‘Juko Potato Harvester,’ we receive superior mechanical separation of Potatoes from rocks and clods – that means less human labor – thanks to the powerful and ingenuous Air-head vacuum separator.
This behemoth Lockwood is 28-feet long and utilizes a color-monitoring-screen in the cab, linked to three cameras, which ascertains Potato flow at three key locations not visible to the operator in the cab.
That expanded-metal sheeting attached to the Lockwood, through which this shot was taken, prevents an overly-enthusiastic worker from crowning Caleb with an ancient glacial rock.
Caleb, Megan & Jim
