Huerlimann H488 no connecting hose

[Daruku]

When putting the Kuhn BTF 4000 seeder and Kuhn TF 1512 tank on the Huerlimann H488 tractor, there is no hose connecting the two implements. There does appear a hose when I use them on a Massey Ferguson 5610 tractor for example, but it does not work for the Huerlimann H488.
