I use Honeybee, they are a rigid cutterbar but float extremely well on the combine, if you run the accumulator and set the header to max float on it's limiting chains we find there is little need to raise header when going through small drains etc. The adapter fastens to feeder the same as any head but the draper is suspended on 2 sets of leaf springs giving it the float. The base header and center draper assembly is the same for all makes, but there is a sub adapter that bolts into the center assembly than can be changed out to another brand, a bit of labour but not as much as a new assembly completely. Or if you are handy with a welder and cutting torch, not that hard to convert old adapter either, may ned a couple of filler plates to match feeder opening, the other issue is depending on feeder speed of other machine the hyd pump may need to be changed as they used a couple of pump options to get desired flow of oil. All in all I am pleased with these headers.
