His job was spraying powerline right of ways for TVA. His sprayer was a Unimog with big tires and big winch on the front. I thought it was one of the coolest vehicles I'd ever seen.
I enjoy seeing tactical vehicles outfitted for utility or other special civ jobs as well .. That mog sounds cool.
In the mid-1980's I recall an area tree company with a jimmy M211 (hydramatic deuce) carrying a custom boom with interchangeable attachments (cherrypicker, manbucket, and hyd saw) .. Everything had quick-pins and hyd quick-couplers...
It was the first time i had seen something that slick..
The manbucket attachment for it did not have controls up top.. The entire rig including the remote saw was run from the operator's seat down below via manual hyd valve levers... No electrics.. The speed of the saw and boom movements had individual dial-control knobs.. .. I don't recall the name of the manufacturer and never saw another one like it...
They also had a jimmy M215 dump with a shopvan-looking homemade cover mounted to box-steel stakes set in the pockets of the original bed.. The cover was rather tall thus the front was boxed in above the headache rack... It towed a chipper which could dispense into the M215's dump bed or directly over the bank ..
No camera on me at the time, but hoped i would catch them again some day.. Didn't happen ..
The first 5-ton I tried to purchase was a M52 gasser (tractor), 1955 IHC.. Priced unreasonable for its condition and unsuccessful in getting it below $9k.. That was in 1985 or 86.. So it sat there for years until it disappeared.. Anyway, a power high-line maint company used it to haul power poles in a log-bunk trailer off-road ... They had taken the front winch and mounted it behind the cab like a M123 .. They said the trailer had sheaves at different heights at the front of the trailer for "skidding" old poles up onto it without needing help from a dozer or whatever... It was a cool setup for a 5T.. I have a pic of it somewhere.
Good luck in your search !!
