Ortolan Tillers

[Floyd1]

Hi im looking for installation instructions on how to install new tines on a 6' Ortolan tiller, i can't figure out how they go on properly. Any help will be awesome. They have to go on a particular way and i cant figure it out. Sadly removed alll the old ones without paying much attention and now the new ones aren't going on correctly, can't find a manual for these machines. Thanks
