| lots of guys do run them manual with good success I just find once you run one with the float optimizer it becomes virtually a drop and drive header. I will try to explain what the float optimizer switch does. it should tie in to the 9500 system without any changes beside some fine tuning of some of the sensor values. I would still check with macdon to be sure. the float optimizer works like a header height control on a normal header, but since the cutting bar is always on the ground it is sensing floatation pressure. it basically monitors the relationship of the adaptor to the header. lets say that with your header just off the ground the adaptor to header value is 0 meaning the adaptor is carrying all the weight of the header and with the header on the ground with the adaptor as low as possible, almost pulling down on the header as a value of 5 meaning the adaptor is just about not carrying the header. so if the header is sitting on the ground and the float number is 1 then the adaptor springs are carrying most of the header weight which may then take about for example 50 lbs to lift the header. now if it was sitting on the ground and the number was 4 it might take 250 lbs to lift the header. so with out the float optimizer and you set it at 2 which might be 150 lbs, as you travel done the level field it will maintain that setting as long as a lot of header travel is not required. as you come up to a rise in the field the header will follow the rise up but you header value may now be 4 meaning less float until the combine climbs the rise to put everything back to the same angles. depending on how drastic the changes are it is not a problem, but it can cause the header to push dirt or as in the case of a gulley have the adaptor carry all the weight and carry it over the gulley and miss some crop. if you manually lift or lower the header it will work fine. what the float optimizer does is when the ratio is set to 2 it tries to keep it there. so as you go into the gulley and the header drops but the adaptor stay in place it senses the adaptor going to a 0 value and will lower the feeder house and when you hit the other edge of the gulley and the header goes up is see the value going to 4 and lifts the feeder house to try to maintain the value of 2. so if your gulley are very gentle you will do fine without it or will just have to run it manually. with the optimizer you will not have to do anything. it also helps prevent corner digging like when crossing a gulley at a angle. the header does have a certain amount of lateral travel before it changes the adaptor header ratio but after that is used up the it lift the feeder house. so I don't know if that makes anything clearer or not. if you watch all the videos on the macdon website I think you will be able to figure out what I mean. | |
