That took some fabricating. I wonder how that would ride? I’ve seen guys reverse the front axle, but I’ve never seen them do a modification like this. ------------- 2-8070FWA PS/8050PS/7080/7045PS/200/D15-II/2-WD45/WD/3-WC/UC/C |

| Some short-line company made those (maybe not that one) many years ago that you swapped out the center tube for a repositioned one and then used your old knees. Seems like the square tube was just ahead of the rear pivot point instead of behind it. |

| Like I say, the square tube is ahead of the rear pivot, so I think it was about a 10 inch extension of wheelbase. |

Any ideas on why this was done? As the Doc has said a company did more than just one or two. As ride quality was already mentioned, from experience a little bit makes a lot of difference. There was a good sized construction company here in California build 1000's of miles of highway. They became the go to for concrete paving for a time. But after a few years all the expansion joints became high spots. Some vehicles rode much, much better than other many times just to due with the wheel base. Many a independent trucker specked trucks the with the wheel base that gave less bucking rolling over the expansion joints. I was told just 2 inches more or less made a huge difference. The state spend a fortition planning the concrete for years. Finally in the last 20 years all has been replaced with asphalt concrete.

We had a 8070 in the early 90s that we turned the front axle around on and made it look like that. Dont remember why we did it but I think it was to get clearance for saddke tanks. Wasnt ideal but it worked ------------- 1984 80780 1957 D14 DES 300 with 25000 engine 616 tractor |

| If I'm thinking right DAKON mfg. made those kits to increase wheelbase. John Day Co. in Omaha was one of their distributors. I have the literature piece , just have to find it., Mike |

Oddly, my buddies Ford 8600’s are like that. He flips every one of his around for shorter wheelbase and a tighter turning radius. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |
