Deere Tractor Imagineer Rolls On

Deere Tractor Imagineer Rolls On TRACTORS Collectors Don Dufner Buxton N D reminisces back to 1958 when he says “I had a lot of time to think while spending 10 days on the seat of a 720 Deere pulling a four-bottom plow over 320 acres It was time-consuming and tedious and I knew I had to be more productive ” In 1960 the energetic Dufner bought a Deere D for $65 removed its front axle and built a sub-frame to hook to the drawbar of a 720 Deere He rode the front tractor while the rear tractor pushed The setup nearly doubled his plowing efficiency The coupled-together rig worked so well that a neighbor suggested “If two are better than one Don I bet three will be better than two ” With that suggestion Dufner bought two more Ds for $60 and $55 and in 1965 put all three together in a triple-hitch Again his farming efficiency improved A few years later he bought two Deere 830s took them apart bolt by bolt and then with engineering cleverness and a lot of head-scratching over three years coupled them together into an articulated four-wheel drive His sons and a neighbor helped A 1994 story in FARM SHOW Vol 18 No 6 described the build in great detail “I had both tractors and they were tired and worn out so we rebuilt them into a 180-hp 4-WD tractor that only burns 7 gal of fuel an hour It has two 75-gal fuel tanks Both tractors have six-speed transmissions so that I can work in third or fourth gear ” The first winter they reworked the engines; the second they spent designing and building the coupling mechanism and mounting the cab from a Deere 8630 They refined the cab the third winter hooking up all the controls and testing its operation Two decades later in 2004 FARM SHOW featured Dufner again Vol 28 No 1 describing his 830 Special featuring three 830s coupled in line The 6-wheel-drive masterpiece produced 300 hp “My sons and I used that for probably 1 300 hrs over the years ” Dufner says “It easily pulled a 12-bottom 3700 Deere plow which we’ve demonstrated at farm shows in the Dakotas Minnesota and Illinois ” It’s also been a favorite at tractor pulls often dragging the sled well past the finish line “I like the 830 because from 1958 to 1961 it had an excellent 7 7L 470-cu in diesel engine It was rated at 69 drawbar hp and 75 belt It was a six-bottom plow tractor that sold new for $5 774 The 830s I used for the triple had been worked hard and I bought them for just a few hundred dollars each ” The front engine of his setup is over the front wheels complete with a hood The middle engine is under the Sound Guard cab over the middle wheels and the rear engine with a hood is over the rear wheels The gear shifter for the front tractor is at the base of the steering console inside the Sound Guard cab The middle and rear shifters are at the base of the seat The three hydraulic levers in the cab are repurposed for three throttles “I can work them together or independently whatever the load requires ” Dufner says A self-taught mechanic who isn’t afraid to tackle any project Dufner was just out of high school when he worked on his first two-cylinder a beat-up old Deere B that he bought for $35 “Everything that could’ve been wrong definitely was ” he says “After I fixed it we farmed with it for several years and it ran great ” That first dip into home shop mechanics has continued for 70 years “I’ve always liked the two-cylinders because they’re easy to work on and efficient ” Dufner says “In 1982 I was visiting with a fellow from Minot who liked that I had about 30 of them He said ‘We should start a two-cylinder club ’ I told him to get it going and I’ll be the first to sign on ” Dufner did that soon after; today the organization has several thousand members worldwide Over the same time Dufner bought and refurbished or restored nearly 200 two-cylinder tractors He and his family used several of them in their farming operation matching the tractor horsepower to the respective equipment “I never bought a new tractor and never bought a 4-WD ” Dufner says “Since I could work on the two cylinders we always had plenty of power on hand ” He still owns several collectible Deeres including some very rare and one-of-a-kind models Several older Deere combines are in his sheds along with a large stock of parts for two-cylinder models purchased from dealers when Deere switched to four and six-cylinder engines In addition to farming up to 3 000 acres for many years Dufner has been a lifelong tractor-pulling enthusiast In 1964 he “pepped up” a 1935 40-hp Deere D and out pulled a new International 706 That gave him the pulling bug and he overhauled engines on several tractors for field work and pulling “A few years ago I put an Allison aircraft engine in an old two-cylinder R ” Dufner says “I had to put it in sideways and when people saw it they thought I was plum crazy Here it is a 1 500 to 1 700-hp engine in a 45-hp tractor My son Dan has it in his shop now trying to figure out why it likes to cough Maybe it’s because it uses 5 gal of fuel a minute when under load ” The pulling giant has 30 5 x 32 tires First gear is set up for 30 mph rather than the 2 5 mph on the original R Now in his eighth decade on the farm and over six decades of rebuilding restoring and maintaining tractors Dufner has turned most of the farming duties over to his sons and grandsons He enjoys maintaining his collection and attending shows and special events “I’ve been at it all my life and I’m going to keep at it as long as I can ” he says with a strong note of determination Contact: FARM SHOW Followup Don Dufner 1148 169 Ave N E Buxton N D 58218 ph 701-942-3102
