Cheap 1850 or Nice 1855?

Store by me has a 1966 1850 for sale, straight, weathered, hoses tired, 21-34's that need replacing. Over/under. Shows 6600 hours. Everything works but the oil smells way too much like diesel. $3850 asking (probably would go $3400 or so).

There is a keyway'd shaft sticking rearward from the injector pump. It looks like whatever was there was removed recently. What belongs there?

A man near my dad has an 1855, 18-34's, duals, weights, nice shape, less than 3000 hours. I have not eyeballed the tractor but non-tractor people who have seen it say the paint looks original and decent, nice looking tractor. The man wants $6800, would almost certainly take $6000.

My dad has about 40 acres that we work, but all of us kids are off farm employed and have maybe 4 days a month to farm. We're doing hay with a 1355 (Fiat) and an Allis B (rakes and hauls wagons) right now, but we are looking at doing tillage (chisel / disk) next spring and want to go quick. Soils are sand, clay loam, and muck (which we don't drive on unless it's dry).

Oh, did I mention that whichever one we get will be the last tractor we get for at least 5 years?

Which one do you think? How big a chisel and disk can these things pull?

As always, I appreciate the guidance.

What engine and transmission does the 1800 have? also, which is newer the 1850 or 1855? If the 1855 is newer then why does it have the "old "oliver engine. What is the rated HP of these three tractors?

The 1800 (A)had a Waukesha 265 engine if it was gas or l.p. or it had a 283 waukesha if it was a Diesel.Three different versions were made(A,B,C)with the first refered to as the checkerboard do to the 1800 name on the side incased in what appeares to be a check/grid design.This tractor was rated at a corrected pto hp of 77.23.Drawbar was at 66.53,as for the diesel they were reated at 73.19 pto or 64.02 on the drawbar.
The tranny in the 1800 is a helical cut and uses the same pattern as the rest,improvements were made in the "B" and "C" versions with the rearend becoming powered lubed instead of a splash lube but to be honest with you I do not know if the trannys were improved on or not.
As for your next question the oliver line goes as follows double digits (77,or 88)then supers(super 77 etc)then the triple digits(770,880)then in 1960 came the 1800 and 1900 or what are called the 100 series,then came the 50 series (1650,1850)then came the 55 series (1855,1955).
Not counting the utilty tractors that were built for Oliver (1450 etc)most of the Olivers used a Oliver designed Waukesha engine with different version from the 77,88 up to the 1755,1855,1955( all of these use a 310 waukesha).The big exception to this is the 1850 which used a 354 Perkins diesel engine or the 1900,and 1950 which used a Detroit 4-53 engine and the 2255 which used a 3150 and 3208 cat engine.
The rated hp for the three is as follows (all diesel)1800 --73,1850 --92hp,and the 1855 --98 hp.But most of the 1850 around here pulled over 100hp and they had a longer stroke and were alot longer life engine than the 310 waukesh that was in the 1855.The 1855 had a bunch of engines produced with bad/poor main bearing caps and also mistake of not haveing a aftercooler,also Waukesha engine was having money problems and rumors were out that they would not cover the engines all these factors did not help in making a very good name for the 1855.hope this helps some

My father, an Oliver freak, claimed the Ollie's were usually rated at about 75-80% of the horse-
power each was actually capable of. His last was a stock 1755 that actually churned out low 90's,
so there might be some truth to his claim. That or he had a long string of unusually good tractors.

Your father is correct,we all need to remember that the numbers Oliver gave out were the guaranteed Hp that tractor would run.

I have ran both,family has owned both at one time or another with the present being a 1850 again.I would take the 1850 it is hard to beat that perkins when it comes to fuel and with what crops are worth you need every bonus you can get.
Also my Dad(early 60s beat up farmer)likes the hydraulic controls on the 50 series bettor claims that they are easier to use/move.
I would also have a hard time finding a waukesha that starts bettor than the 354 perkins that is in the 1850.
As far as the three speed in the 1855(over/under)you can always put one in the 1850 down the road( in 1968 Oliver started putting them in so 1968 year 1850 had over/unders too)

I have both an 1850 and an 1855 (although my 1855 had the engine changed out and replaced with a 1955 turbocharged engine ). I agree with Larry's comments and would add two . my 1855 starts better in cold weather than the 1850 although this may be because of the turbocharger . The 1855 has a tighter gearbox and is more difficult to shift than the 1850 . If you are going to be using the tractor in a way which involves changing the gears a lot or changing directions frequently the 1850 may be better . Finally , my 1850 has a hydradrive shifter which allows you the option of two speeds without changing gears while the 1855 has an over under shifter which gives you the option of three speeds without changing gears . If this is important to you you might check the ones you are looking at to see what they have . When these units fail people sometimes completely remove them rather than repair them .

On the 1850 nothing goes on that extra drive shaft. On some MF. tractors there is a small pump. I like the 1850's best because of the perkins engine. The 1855's have the old oliver engine that had lots of problems. On the plus side everything on the 1855 is power operated,brakes,pto. The 1855 also has a closed center hydrolic system which is hard on pumps. I use a 5-18" plow and 19' disk on a 1850,both tractors are nearly equal in pulling.
