this film is on a wd-45, as i could not find a good film on the wd.
but well worth the watch, they were great old tractors,
i had a D-14 that was Suppose to replace the wd-45, but it would not do it.
just understand the old AC tractors did not have a (live clutch) they had a hand clutch to run the roto baler and combine,
but, for a bush hog the pto must be stopped for you to change gears forward to reverse and back.
with a bush hog, it take the hog a while to stop turning the pto shaft, and the tractor can be hard or not be able to shift until the pto shaft stops turning.
this is the only problem i ever had with the old D-14, otherwise i liked it.
however it worked better with snap couple equip.
