John Deere Upper Doffer Adjustment
Housing and Sprockets Assembly

Shop by Image

Cotton-picking machines are critical to cotton harvesting. Multiple parts go with the machinery and each component. The upper doffer adjustment housing and sprocket assembly is a section that may have parts needing replacement. The chart linked here shows available parts making up the assembly. Tolerances are important when manufacturing components that function together in an assembly. Components for the upper doffer adjustment housing and sprockets assembly are no different.

Aftermarket parts are compared closely to the OEM style, and they fit the same. The only difference is the name brands are not the same. Dealers push to sell aftermarket products because they know people will buy more if it is more affordable. The farmers find they are less stressed during the peak of the harvest season because they know there will be little to no delays when waiting for parts to come in.

It takes the correct alignment on the shaft of the doffer. An efficient harvest depends on this, along with proper maintenance. When the parts go into the shop for repair, you can expect the mechanic to have all the tools necessary to put together the doffer assembly and grind the doffer’s surface. Grinding the surface allows for maximum use. The mechanics will also check the abrasiveness so that the cotton is stripped from the spindles when they flow by. All adjustments are made, and everything is double-checked. Knowing the parts that were there when needed is the most extraordinary relief.

Any machine can break at any moment and shut down the harvesting operation. It doesn’t take much to stop the components from working correctly. One tiny piece can fail and stop the component from working or break it completely. Certi-Pik, USA keeps even the most minor pieces around and can have them ready in little to no time, so the farmer or the mechanic can fix the machinery and the farmer can continue the harvest.
