Maybe you've watched the Mecum's auto auctions on television with shining collector cars and antique autos rolling across the auctioneer's block. A "Gone Farmin'" version of it wheeled through the Pennsylvania Farm Show Complex at Harrisburg, Pa., on Aug. 1 with 107 tractors plus collector signs and clocks.

"This was Gone Farmin's first auction in Harrisburg, and we're pleased with the results," reports Dan Mecum, president and founder of Mecum Auctions' Gone Farmin' division. "The crowd brought a lot of energy which made for an exciting auction day."

OLDIE BUT GOODIE: This 74-year-old Deere GPWT hammered out at $12,500.

Some 82 blue, red, green, gold, yellow and gray tractors and other collector items sold, generating $537,200. Top seller of the day was a 1972 John Deere 4000 Diesel that hammered at $36,000. It drew the hottest bidding because it's one of only 428 diesel powershift 4000s built.

Next came another green machine, a professionally restored 1971 John Deere 2020 pulling a top bid of $23,000. Another sale highlight, according to Gone Farmin' President Dan Mecum, was a 1953 Ford NAA Jubilee that sold for $18,000.

Oldest tractor sold on the block was a 1931 John Deere GPWT, a 10 hp, kerosene-fired two-banger going for $12,500. A 1921 Fordson had 10 years on the Deere. While it didn't bring the seller's wanted price, it went into the 'Bid Goes On', Mecum's post-sale platform where people can bid on items after the live auction.
