Opinions on a 76 F 600 with allison auto.

I have a chance to buy a nice 1976 F 600 cabover with what I think is a 391 and an allison auto. Has anyone had experience with the older allison transmissions? Figure hauling 300 bushel of corn in hilly country. Also, what would an original truck with 40k with nice sides/bed be worth in your neck of the woods?
 
Air brakes? If not ask what yer life is worth. I'd leave the damn thing for the wreckers personally.

My 1972 GMC with a 350 gas and Allison transmission hauled 300 bu of wheat out of the fields for me every year and is still doing it for my neighbor. Up hill was bad with the 350.
 
The ones I have driven had a super low that had all kinds of power. Be sure to have the engine at idle when you shift into low.
 
Guy I worked for 100 yrs ago had a 67 tandem I think it was an 800. Had the 6 speed Allison and we hauled 500 bushels with that thing. His son still has it and uses it every fall. Last time I talked to him they have never done any repairs to that trans. After you drive it awile you will get to know when it is going to shift at what rpms and we always let up on throttle to let it shift. Owner thought that would be easier on it and I do to.
 
The automatic will take some power away from the engine but I drove one for a previous employer, and I really liked it. If you can get it worth the money, I'd go for it.
 
I had a 69 f-800 tandem with a auto in it (believe it was a allison).. I hauled 300 bushels on mine (all the higher my little combine could reach over the sides.. I cut a foot off of em)

I ran to the elevator with the foot on the floor.. 54 mph loaded, 58 mph empty seemed to be the best it would do.. so I just stayed off the expressway and took county roads. It was geared really low.. would crawl its way through a lot..

I had air brakes.. and loaded they worked good.. really touchy when the truck was empty though.. if your foot was on the brake and you hit a bump that moved your foot on the pedal you'd likely eat the steering wheel.

My grandpa bought the old girl used in 79, and I bought it from him in 2002 or 2003.. The 2 of us never had a tranny problem.. I had a drip from the output seal, but sitting the better part of a year it wouldn't drip out even a pint. Driving it would drip a little more, but still nothing serious.

Wish I would have kept the old girl when I gave up tryin to farm.

We have Allisons in all of our trucks. They work really nice pulling out of fields and backing up to things. That truck better be dirt cheap as sometimes you can't give cabovers away. If it fits your needs and you like the truck, don't be afraid of the Allison.

A few years ago I sold some parts to a guy who runs dump trucks that have to go into a city and he had bought an auto for his wife and he liked it so well he said his next one would be an auto too.

The older ones don't have an overdrive but most local farm trucks don't need them often.
 
good point on the brakes. Air would be better/best for hilly roads. The auto may not work as well to "hold" the truck back, but on the other hand, and auto will always find low, finding a gear in a manual when you're already started down the hill isn't always good either.

I presume you're looking at one of the old Cab forward aka "Budd-cabbed" Fords (cab made by Budd company for Ford and Mack) Always thought those were neat looking trucks. Only the euro's and asians still make cab forwards.
 
I had a 73 F-600 with a 361 4 speed with hydro brakes.

The brakes would put you through the windshield unloaded, worked well with the 16' dump bed over loaded with rock.

The booster went out one day, I had to stand on the brake peddle with both feet and it still did very little. I was in the woods unloaded when the booster when out. Got it back home and replaced the booster.

Same good brakes on a 1979 F-600 a company I worked for had. The company also had a 1968 or 1969 F-600 and for some reason this truck never had the same braking power. Changed boosters, vacuum hoses, master cylinders, wheel cylinders. Nothing ever helped this truck.
 
You're lucky....
Most around here that had the damn things had many hair raising experiences when a line popped for no particular reason and then had the choice to ride it out or ditch. One guy I know nearly died when he decided to jump... but he felt that in the situation he was in death was more certain by not jumping...
So... every one else can have their blasted hydraulic brakes. I'll stick to air. They're more effective, more reliable and cheaper to repair/replace.
