856 gas

Saw a for sale ad on C-list for a IH 856 gas. Got me wondering how much that gas that would consume when working it hard. Probably a lot. Bill

Have a price ? Location ? Could be a very collectable tractor.

Nebraska Test show an 856 diesel using 6.6 gallons per hour at engine speed rating (2400 rpm). I would guess a 856 gas would be around 8 to 9 gallons per hour.

Lots of horses under the hood. If you're going to work them, they're going to have to be fed!

560 Gas routinely used 5ish gallons plowing. 2.5 for light duty use. Most people who buy that large of tractor use them because it will run very easy in the cold and is a larger tractor in feed lots, not caring how much it uses but is there when they need it. A 301 in a G gleaner would use upwards of 8 combining all the time, so I suppose about the same. Funny thing is a 401 in a Uni-system used about 5 chopping corn at full maximum capacity. Very few people use them as main tillage, just for novelty

well depends on what your going to do with it . Then the next question is where ya going to find the gas to run in it ?????? That is the biggy . The gas you burn in your car does NOT work . NO it is not about the lack of lead , it is the lack of octane . Min. octane rating on any of the gassers built from 1963 to the end of the gas era was 93 octane . when they were NEW normal PUMP regular gas was 95 octane and the Cheap stuff like sunoco 190 was 93 octane Gulftane was 93 and that stuff would make and old wore out chevy 6 cyl. pick up ping and knock . I personally ran gas tractors for years , BUT they ran on the same gas that i ran in my pick ups . Since my first F 250 4X4 in 73 was only stock for a week . I hated that 360 V 8 with a passion a gutless gas sucking pig . I happened to have a new in crate 428 Super corbra jet one of the last from the drag club days when ford got out of drag racing . With the changing of the oil pan the pick up tube dipstick and one main bearing bolt it dropped in . and with a 11 to1 compression ratio it needed more vitaems . So on Saturday mornings when i fed the truck i filled the tank to feed the tractor with the same gas and continued to do so up till we could not no longer get even the 93 . And what happens when you TRy and work a I H gasser on the Cheap stuff , well you will eat PISTONS like M&M's as a friend found out then his brother found out when his kid put reg gas in there 706 while just mowing hay , then another guy learned the hard way on his fresh engine over haul that i did not do and it ran for a whopping 30 min. when it seezed up scoring ALL 6 .I sold a lot of 706 gassers in my area to smaller dairy operations due to the ease of cold weather starting for winter work and chore tractors and as long as we had REAL 93 octane we had no engine problems and everybody loved them . The cost per year was around 350- 500 bucks more over the cheap stuff . The cost was less then the cost of keeping a diesel plugged in less then and injection pump rebuild , less then and engine over haul . The next think ya need to know about I H gassers is the fact they need a low ash oil or they like to munch exhaust valves ,another lesson learned the hard way.

Nebraska Tractor Test #859. It looks like 806 gasoline tractor used 7 1/2 gallons per hour to make 93 PTO HP at full load and 2400 RPM and factory engineers keeping it in tune. That is pretty good for a large gas tractor with a C301 engine. The 856 gas used the same engine and was not tested.

Neighbor had a gas 806 that was bored out to the max and pulled a 6x16 plow. Said he had to fill up every two hours!

I don't know about the 856 but my 806 Diesel was 4 gallon per hour plowing and that was an all day run would go on one tank and refuel for night working. It has the Rd pump not the Roosa Master pump.

Sheboygan WI c list. not mine. Bill
