What would a Oliver 1850 be worth???

I am thinking about doing a trade with a fellow. I would end up with an Oliver 1850 diesel. It has 5300 hours verified, narrow front, Good tires front and back. It has the Hydra electric valves. It does run/drive really good.

I am thinking it is worth about $6500-7000 retail. Is this high/low??

I have thought about keeping it. If I did I would want to switch it to the float/detent style hydraulic valves. To do this I would have to change the entire top housing????

Would the housing off an Oliver 1750 fit??? I know where there is a late Oliver 1750 setting with a bad engine that I can buy cheap. Are many of the parts between the 1750 and 1850 common??? The 1750 is a late one with the three speed shift.
 
You will not be able to make those valves float. A 1750 will not be able have a float either. You will have to go to a 55 series to be able to get a float valve and those units will not interchange with a 50 series. To get a true float you will have to hook up a power beyond and put on an after market valve that has a float position.
 
I have an Oliver 1655 that has the detent style hydraulic valve. I just open the internal ports to get float/single acting function for one way cylinders. I think this is the style valve that is on the 1750 I know of.

If I where to keep this tractor I would be using it on a hay rake and possibly feed wagon. I do not really need float but would need the valves to detent to run hydraulic motors without having to hold the lever all the time.

The Perkins motor is my main attraction to the 1850. I also like running my 1655 and the 1850 would be very similar.
 
JD, Yesterday at a local auction a 1650 with loader brought $3200 another 1650 brought $5100. An 1800A narrow front not running brought $2200. Two 2255 open stations brought $16500. There were 3 open station 2255?s the last one brought $14000. Big old JD 8630 with trans issue brought $8300.

At a farm auction in Bergton VA last Fall a nothing special 1850 that ran and operated seemed OK bought $3300,thought it was a good buy but not good enough for me to bid on it.
 
I think you're high on the price. It takes a pretty nice 1850 diesel wide front to bring $4500 in the real world. I bought mine about 23 years ago,one owner with 4700 hours,always housed. I gave $5700 for it. They haven't gone up any since then.
 
I think your concerns about running a hydraulic motor with it are valid. I ran that John Deere 700 grinder mixer with mine. It had a hydraulic drive auger that fed the mill. You could buy an open center speed control valve from Deere for those grinders,and I did. The oil would get pretty hot in that tractor just grinding one load of feed. You couldn't lay your bare hand on the filter housing for more than a few seconds.
 
Not trying to stir things up, just an honest question. I've had my 1850 for forty years now, and the 1655 for twenty years. All during that period if the tractors are worked for any amount of time the filter housing is hotter than I care to grab onto. So what is the normal temperature for the hydraulic oil? Just wondering.
 
My cousin got a float valve to work on his 1850. It's a late model three speed. I know because I drive it all summer pulling a double Kuhn rake. Guess I never studied what he did, but I pull up a rod he added by the levers and the rake drops on float. Push rod down and then use lever to raise rake.
 
Thank you for the information!! I will more than likely pass on the deal. I would have more in the tractor than it is worth.

I just like running some different brands of tractors. I have the 1655 on an eight foot rotary cutter most of the summer. I just like using it to keep things trimmed up. The extra HP on the 1850 would allow me to use it on more things.
 
your are to high 5range and below what I have seen, in fact go to steffes auction site they have going on right now beik farm auction bunch olivers go look,not sure if there was 1850 thou 1800 was on and several smaller units
