Combines anything bigger then 75

The crystal ball holds a class 8 Gleaner. The testing seems as it will be based on the MF rotor design. The engineering thought is it will be less expensive to go this route rather than with the Gleaner design. (Dan H and I disagree) Word from those who have run the big Masseys, and we have as well, say they have tremendous rotor capacity. The biggest MF today has a smooth flowing rotor. There is one problem with these big machines of all non silver colors- terrain slope limits shoe capacity. Most farms have slopes to contend with. It doesn't matter how much one puts through the rotor, if it can't be put in the grain tank efficiently it is of no use. The cylinder in the R and N Gleaners lend themselves to the use of the accellerator rolls which overcomes the force of gravity which is the cause of most shoe loss on slopes. This can also be overcome with self leveling shoes and or combines. However in class 8 size the frame to support 400 plus bushel bins and unloaders to unload past 45' heads and 16 row corn heads yields list prices on unit and both heads of a half million bucks! Try to pencil in the harvest cost per acre and the old point of diminishing returns rears its ugly head. We have heard here of producers harvesting 3000 bushels of corn per hour with an R72. Very few farms can handle this grain flow very long. It soon becomes more practical to run two smaller than class 8 machines and reduce the amount of hours per year put on each unit plus the factor that All machines will have to be stopped for breakdowns; (I don't know of any company who has stopped producing repair parts) a producer depending on a single class 8 machine which could throw a rod during the start of harvest calls for some serious thought.

Your right and I'm with you Tbran. Nothing against the MF combine but don't paint one silver for me. I'm all for Natural Flow and know the R75 is not maxed out now even with a certain amount of so called hyperizing. If someone is ready for a so called class eight from me I will build up and sell them a R75plus and save them tens of thousands. I was going to say sell them a R75plus for price of R85 and pocket the tens of thousands extra but I couldn't do that!!! Thanks for your infinite knowledge and support Tbran. Oh yea, Good job basically doubleing capacity of the factory R75 the other day right in face of factory man. Isn't it amazing what these machines can do in the toughest conditions with just a couple tricks. I know your not amazed for you've allready been around it for a few years but how about the factory man. Sorry Tbran but you must of touched a nerve with that MF bodied Gleaner class 8 stuff. Good bye for now.

I really enjoy this board and the info is tremendous,but why doesn't the factory add a lot of the hyper mods as standard equipmentIJIs the company afraid to give credit where credit is due to the people who see and work on these machines many times a year,and are not afraid to modify them to reach more potential.Again the guys on this board are great.

Hi tbrain have you seen this new unit, have you worked with it, when will it be out. What is involved in making a 75 a plus. What was dan getting at about the factory guy. Could gleaner not make a class 8 out of the natural flow system. I now if they do change over to the massey design i will be looking at a new color. Thanks for your time. Colin

Truth of the matter is they are listening and they are making changes at there own speed. They are very very careful to do the homework before changing something to standard. Some things are quicker than others. Shocks were introduced and installed within a year of them finding out about them. Extended cylinder bars were longer but they did the right thing and made them standard. I'm confident plenty of other things are ready to come out of the pipe. Some company men are quick to give credit where it is due and some would rather cut their own tongue off. Not a whole lot different anywhere else that I have seen. I'm sorry to any company men if I got a little mouthy hear but I get a little edgy when it seems the MF is getting the RandD and Gleaner left behind. Have a good day.

I know they need to research the mods,to make sure they are practical,but just one example ,splitting chaffer adjustments,should have been standard years ago.I have talked to an engineer from Agco and he was very receptive,but some of these mods need pushed up to production level.I too hope they use the Gleaner design for a class 8,because as good as the Massey is it still has limitations.Have a good day.

One of our combines is working right beside a CR 970 with a 39ft head and it is still not worked to it's full capacity in most crops. The same as our R72, a R62 will stay with it in most conditions with our crops(no corn)so maybe these supersize babies are just overkill for 90% of the time

What is wrong with your 72 why can't you get it to capasity. How is the 970 doing.

There is nothing wrong with the R72, it's just that unless we are in irrigated or muddy conditions here we rarely use the horsepower.In irrigated sorghum (milo) we have harvested over 3000 bushels per hour but the problem is keeping the grain away for a lot of farmers. The CR970 is running a 39 ft Honey Bee and on the second Day the knife snapped as we are in unripe chickpeas. It seems to be more reliable than the CX860s'that are working there but more hours are needed on the clock to see how they will last.

i run 42 ft hb headers on mine and when i am picking up a windrow we have 60 feet going in to the machine that way we keep the speed down and keep the combine full.
