View Full Version : 1480 vs 1680

Double ll, since nobody replied, I'll give you some insight on this. As far as differences, here are some specs. between the 2. A 1979 model 1480 would have a 190HP DT-436 engine, if its still original, the 1680 would have a 225HP DTI-466 engine. Grain tank, rotor size would be the same on both(either could be a standard rotor or specialty rotor, although the specialty wasn't really offered much until the 1600 Series), cleaning system would be about the same as well. The 1480 would have mechanical hydraulic control instead of electric-over-hydraulics on the 1680. EOH units have the controls arranged a little nicer,easier, in my opinion. The 1600 would have a feeder house reverser(not many 14s have them) which comes in handy; the 1600 have a concave extension, allowing more concave area. The 16s also have a better shaft monitoring system than the early 14s did, also probably has a grain loss monitor that the 14 don't have. 16s have better cab lighting.

There were several changes to the 16 series that corrected shortcomings on the 14 series, but I think you should compare 80's to 80's and not 1480's to 1660's. Also the older IH combines can all be updated with most of the improvements and fixes that have come along over the years. So on these older combines you pretty much have to go on an individual combine by combine basis as too how much fixing they will need or how they are configured.

Personally I think a 1480 would cut more than a 1660. We have a lot of 1670s in our country which are basicly a 1660 combine with a leveler and a 1680 motor and they are comparable to a 1480 in wheat and barley. The problem is you really have to take it on a machine by machine basis a 1480 could have either a 466 motor or a 436 motor which is going to make a diffrence along with a 1680 could have a 466 or a CDC along with being either a short shoe machine or a long shoe machine. They changed quite a few things on the run so its important to know the trade-offs

1480 will run circles around 1660, if both are set-up correctly.

The clean grain elevator on the 1680 will give you more capacity. Not sure about the long sieves We run out of elevator in tough milo with the 1480. We need the horsepower the most in heavy, tough wheat and mud. I installed the scroll fan kit several years ago and that solved most of the cleaning problems........well worth it. I'm running an air foil chaffer too. We can run 4.5 to 5 mph in good (125) corn here. About the same in good milo, if it's not over 17 moisture. Seems like the only good beans I ever cut really pulled the guts out of it. I cut so few beans, so that isn't a big deal. Just bought a 2388 last month and cut some really good milo (115) in mud............that machine never even whimpered! Can't wait to see how it does in good wheat.

Here is info from the www.hoober.com Axial Flow history page on the differences between the 14 and 16 series machines. "1986 Introduction of 1600 Series Axial-Flow Combines 1620 124 H.P. 358 Cu.In. 125 Bu. Grain Tank 1640 150 H.P. 466 Cu.In. 145 Bu. Grain Tank 1660 180 H.P. 466 Cu.In. 180 Bu. Grain Tank 1680 225 H.P. 466 Cu.In. 210 Bu. Grain Tank Capacity increases of 70% on 1640 and 1660 and 25% on 1680 Increased concave area by 15.5% on 1640 and 1660 and 16% on 1680 Increased separating area by 24% on 1620, 32% on 1640 and 1660, and 41% on 1680 Cage vanes adjustable without removing bolts or concaves and grates Clean grain augers increased in diameter (7" on 1640 and 1660 and 8" on 1680) Deeper clean grain elevator cross section (11.1 x 6" on 1640 and 1660 and 11.1 x 8" on 1680) Tear drop clean grain elevator lower boot Tapered entry design into clean grain elevator boot Inclined delivery auger standard on all 1680s and 1660 rice models Shaft speed monitor standard (monitors 9 areas, two more, feeder and spreader) Improved lighting package (6-60 watt halogen lights including one long distance light) Optional feeder reverser all 1600 (field kits for certain 1400 series) Introduction of 1020 Flexible Cutterbar Header 1.5" knife system standard on 1020 Flx. Optional on 1010 Cross auger lifts with reel lift for reversing" I would hold out for a 1688 if I were you.

got all the information from the web site, am looking for real world info from someone that has had both of them. thanks. but i am thinking of waiting for a 1688

We are basically in the same situation as you are. We are currently running a 5500 hr 1480. There are some who would say the DT466 is actually a better engine than the early Cummins. I've never run the Cummins, so I can't say. HP between a 1480 and a 1680 is the same. You don't say how good the corn is, but we can run about 4.0 MPH in 160 bu corn. 200 bu corn this year was 3.5 MPH pulling down to about 2580. Beans is totally dependant on the beans. Varies from 2.5 to 5.2 MPH with a 24ft head. We put in a Hillco fan Kit(available from Marvin Gordon) in the middle of the season last year. It made a noticable difference in grain loss in Milo, and cleaned up the sample a lot in Soybeans. I Wasn't very happy with capacity in Milo this year, about 3.0, untill I was final figuring yields last night, and realized the whole field averaged 155 bu. A test plot had yields of 180 bu. You don't get a HP bump untill you hit the 88's. And you could actually get it out of your 466. A local tech and I were Bullnnnnn the other day about our combinse. He's running an 84 1480. He already has the crossflow fan, and is thinking about putting in the long sieves. The cage and concaves from a 2388 will fit right in. I need concaves for next year, and the whole cage and grates is only $2200. Clean grain elevator wouldn't be that hard to change up. I guess I'm just rambling now, but the basic point is, you could update your machine a whole bunch(if you're mechanically inclined) for what it would cost to trade. Personally, we decided to keep our 1480, and keep it running, untill we can step to at least a 2188. Chads
Have an 84 1480 and have leased 1688s. There is a big difference in capacity. You would be amazed at the difference. 1688 is a great machine. I don't think you would see much difference between 1480 and early 1680.
I have a 91 long shoe 1680 w_cummins (high rpm model). Previously I had a 1987 1660 and there is no comparison - the 80 series made harvest much easier for us. I help a friend out and he has a 1480 with special rasp bars, air foil chaffer, disrupters and a new 466 engine. Generally my 1680 is more machine than his and with the longer cleaning system is not as difficult to set. However, he has had his 1480 forever and really knows how to get the most out of it, so the difference between machines is more about comfort and fewer worn out parts than it is capacity (ie: it's really not good to go 6mph w_ a 25ft head in beans even if it will take it). I'd say hold out for a 2388 - they seem to be the best CIH as made for a long time and maybe they will get cheaper someday. Pat
Watch out for the 1680 engine fires here in Montana I can't even count how many fires they have started mostly due to air flow across engine compartment . 88 series is twice the machine. I have 2 of them for sale 93 and 94 only ever had small grain allways shedded one owner like new 2000hr if interested e-mail they come with 1010 30' and a pickup header either one for 55ooo
