Welcome to the Forum. After you make your second post, you can access manuals. Upper left, click on "quick links", then "PDF manuals". The 100 is under Farmall Cub, then "Cub attachments", then "spreader, carrier, trailer". I don't think there is a manual for the 200 here. I have that manual if you have specific questions.
Edited to correct comment about 200 manual.
