ford f350

Farmall49 · Dec 20, 2017

I bought a 1970 ford f350 dulley ford 250 dollars not sure what motor it has in it I would gues a 390 or 460 it has long frame with a flatbed and crane took the crane off this idea might be a little crazy but seen done before I have a 100 bushel gran chopper on tires I want to tale axel off of it and mount it onto the pickup the chopper used to be run by tractor I have herd theses pickups have a place for a pto but don't know what speed the pick runs so how would I get it to 540 pto speed I will build a shaft than runs to below the chopper and run a belt or chain up to it I would have change the air intake for more dusty conditions and put some sort of governor on it I will also mount a singing auger that feeds the chopper that will be run off the trucks pto the reson I am doing this is so we don't have to unhook a tractor the auger will just swing out instead take 30 min to set up we chop semi loads of grain a week all will be with one machine what are your guys thoughts or suggestion's thanks

I might be wrong on all this, but i don't think the pto would work for a 540 setup. I think they're pretty light duty and turn much slower, for running a hydraulic pump for a dump bed. If it matters, a couple pictures posted of the engine would at least identify the engine family

How much power is needed to run the chopper? I assuming the truck already has a pto box on it, and the pto box at the max are only good to about 210ft lb of torque, and about 40hp.

There are bigger PTO units for truck transmissions, but that older F350
is not likely to have a transmission that would accept the bigger PTO box.

Most likely a 1970 has a 360 - possibly a 390 engine. The 390 was the biggest engine put the f Series 5th generation.

70 F-350 should have a 360 or 390 FE series engine
Should also have a Borg Warner T18 or New Process 435 4 speed trans.
The pto's available for ether trans is only rated for 40 max hp and 200 lb torque output.

One can chop with a 40 tractor but you'll be feeding it pretty slow.

The pto will cost around $1000 and not sure if one is available to give 540 rpm at proper engine speed, if not a gear reducer will be needed as well, one capable of handling 40 hp will cost a couple thousand or more.

Governor from a old Chevy powered Massey combine can be adapted to run off the Ford engine

Putting a grain chopper on a truck chassis is a nice idea but not sure if it's worth the cost just to save a few minutes hooking a tractor up.

You might want to consider mounting a old tractor engine on the back of the truck with the chopper using it as a power unit to run the chopper.

(quoted from post at 07:11:06 12/21/17) There are bigger PTO units for truck transmissions, but that older F350
is not likely to have a transmission that would accept the bigger PTO box.

It either has the Borg Warner T18, or T19 transmission, I wish I could find a 1970 F350 dually for $250. I got a old 3 yard dump bed, and that F350 would be perfect to put that dump bed on.

What trans could I put in it that could give a 100 hp pro box what to do this also so we can chop at all of are feed lots 20 miles apart which one machine found out it has a 390 how much hp dose a 390 have how will it hold up to it should I use a belt or chain to run it

Just so I fully understand is the 100 bushel grain chopper your referring to the same thing I call a grinder/mixer.
It has a hammer mill to grind/chop corn or other grains and sends it to a mixing tank to be blended with what ever other feed stuffs you want mixed together, then has a anger to unload the feed to feed bunks or bins.

I have a Gehl 95 grinder/mixer I use to grind ear corn for cattle feed.

we same choper as you

ptfarmer · Dec 22, 2017

What I would do to use the truck is find something like a Ford 300 6 cylinder, or a Ford 2.3L 4 cylinder industrial engine with a governor (you may have seen them running tree chipper/shredders), and mount it on back of the truck. Find out what the maximum rpms the governor lets the engine run. If the governor lets engine run (lets say 2000 rpms), then you can gear it down so 2000 rpm is 540 rpm. You would be gearing it down almost 4 to 1 to run the mixer, it should have more than enough power to run the mixer. It would probably be a lot cheaper than getting a transmission/pto box that can handle the power the mixer needs. Either that or find a old, beat up 60+hp tractor at an auction, or something to run the mixer.

I have a 71 F350 and the 4 sp is a np435 and the engine is a 360. Only way to tell a 360 from a 390 is the stroke.

Destroked 450 · Dec 22, 2017

Agree with ptfarmer.
Set the chopper on the truck bed with the mixing tank near the cab, then add a power unit on the back to run the chopper.
I still won't want drive it on the road with a tank full of feed, could be pretty top heavy
