Yes I think so - the screenshot is taken from the document in the manuals section, which has no explicit date, but is labelled:
"Printed in U.S.A. 1st Print MF 10 Garden Tractor 651 219 M93 (Issue 1) 11/66"
at the bottom of each page, from which I am guessing it was the first manual released in November 1966. Moreover, the pictures in that very nice colour sales brochure that FirefyterEmt uploaded a while ago, which was published when the MF12 hydra came out (1967?) shows the early MF10 with none of the later decals on it.
There is a later parts book in the GT Manuals section in which page 65 shows the "Variable Speed" "Do not tow" and "Shift only when engine is running" decals as well as those shown in Issue 1 - that page is from "Issue 2 1/71" which suggests these came in around 1971. The yellow decal, implement and hood release ones all seem to be later still.
