The “dropArea” is the same for the tedder as it is for the windrower. I think what you’re experiencing is that some maps have a <converter factor=some number larger than 1.0 for “TEDDER”. This will be in the maps_fillTypes.xml. If it’s more than 1.0 then tedding will increase the amount of hay by whatever factor is set. This can cause a giant windrow that spills out both sides as it’s dropped out of the rake. If this is the case, I can’t change anything about the rake to fix this. Sorry!
