I think that the 60 series had better header control options in the cab, the one piece hookup on the feederhouse and a different air distribution system on the cleaning shoe. I would think that in small grains the 9660 would be prefered to the 50 series. Don't have any idea in corn, how they would compare.
You could easily chip the motor on a 9660 to get the 20 hp.
Some of the later built 9750 combines had the 12.5 liter engine.
Power chips cost around $400-$600. Yes, fuel economy will be better. There are a number of different chips available for 9750's but there are 2 styles- '00 and '01 Tier 1, '02 and '03 Tier 2. These fuel systems are very different.
Don't ever buy a 9750 with the 12.5L unless you enjoy changing rotor belts, the "Canadian Special" has the same capacity as a 2004 9860 but the rotor drives are weaker. I have talked to guys that have them and they hang 1 or 2 rotor belt on the side of the combine cause they know they will need them. I would take a 9660 over a 9750 any day, the 50s are first generation are a little rough around the edges , the 60 series are more refined and reliable. Just chip the 9660 to make it equal to a 9760.
For those of you who have older S-680s or S 690s I have a few questions.
I put 325+ separator hours a year on a 2014 S690 and am trying to figure out an average yearly repairs/maintenance that other people have with similar machines. I'm not including header maintenance, lease/ownership...
Im returning to the farm after 20 years and Im starting to update "within the last 20 years" some equipment. Anyway I purchased a 1996 John Deere 9500 on auction that has John Deere Greenstar yield monitor. Everything except the display or a gps. Im very new to precion ag but can anyone tell me...
Hey I have a 9670 with a very sloppy turbo actuator linkage it's a simple little rod but jd seems to think it's worth 770 bucks for something I can hold in my hand . Does anyone know where i can get one alot cheaper? Any feed back is appreciated thanks.
I need to buy the tractor 9rx for seed sowing air drill N540 C.
I need to know
Fuel consumption per hour at full load.
Hydraulic oil consumption
Speed per hour how much area it can cover with the N540 C.
Consumptions and Maintenance for the N540 C
Also, what is the current...
I am going to replace the accumulators on the TLS on my 7720, both are weeping oil out the pressure caps and are no longer letting the suspension move.
I am going after market at this stage, should be 60% of JD. RE306377 AU$930
So my question is what pressure should they be pre-charged...
