John Deere 7760, A Picking Reveloution

This was originally going to be a post about the process of cotton picking but as I started to write I thought it should be about the John Deere 7760, the machine that has changed the way cotton is picked in Australia.

The John Deere 7760 Round Baler is a textbook example of how a technology can be taken up and embraced by an industry, since its release for the 2008/09 cotton season  it has taken hold in the industry with nearly 100% of operators now using it over traditional methods. This uptake has not even been seen in the USA where many smaller operators (under 4000 acres) still use the traditional picking crew, the success of this machine has been so great in Australia that it has been said that the John Deere Dealership in Moree has sold 16 of these machines in the past year, not because they could only find 16 buyers but because head office capped them at that amount (I can’t confirm this as I haven’t spoken to the dealership, its just the word around town).

The main reason for their success is that they have been able to cut a eight person crew down to two or three as there is no longer the need for a boll buggy, module maker or the many tractors needed to run these machines. Before the release of the Round Baler cotton picking was a very labour intensive process, the picker would pick the cotton before dropping it into the boll buggy being pulled by a tractor similar to a header unloading grain into the chaser bin. The boll buggy would then empty the cotton into the module maker which would then compact the cotton into a module the size of a truck trailer, once the module has been built the module maker gets towed on and a large tarp is fitted across the top to protect it from the rain. The Round Baler reduces the labour required and simplifies the process by making the module on board while still picking the cotton, when the module has been completed it is wrapped in plastic by the machine to protect it from the rain and dirt and dropped out the back. If the picker is still working the row the module can be carried along on the back of the picker while it continues to make another module on board, if the picker completes the second module while still in the field the module on the back can be dropped in the field to be picked up by a loader or tractor and the new module gets the piggy back ride.

John Deere was not the first company to release a module making picker as the Case IH Module Express 625 was released a year before in 2007 but it never took off in Australia, I have only ever seen one on display at Ag-quip in 2008 and as far as I am aware only one has ever been bought in Australia. It had couple of problems that left it uncompetitive with the John Deere 7760, one was that it was never able to get a heavy enough weight in the module meaning you needed to make more modules for the same amount of weight, another issue was that it still needed to have tarps put over it unlike the round baler were it is wrapped in the making process. But the biggest problem with the Module Express was that it didn’t offer non-stop picking like the Round Baler does, it has to stop to empty the module at the end of the row when it was full and then start picking again.

The John Deere 7760 Round Baler has changed the Australian Cotton Industry to the point where in five short seasons it has totally replaced the old methods of picking, thanks to the increase in efficiency, reduced labour requirements and the enhanced protection of the module.  If you have any questions or comments feel free to leave them below, check out the last post to see some video’s of the of the John Deere 7760 in action as well as the a chain bed truck being loaded with cotton modules.

If you look carefully you can see a completed module riding along behind the picker
