Info for twenty planer

Moulding, I wonder if that gadget is one that made use of the dual PTO that I've seen in parts books - it has two shafts coming out the back and I guess could power the two controls on that planer?

Scott: Great find on your 20 Planer!! It was manufactured in 1930, there were a total of 310 manufactured.

Thanks it was found on the bb and posted by u-joint . Maybe if Im lucky I can find a parts book or early advertising for it . I think this planer is controlled by two wheels mounted on the rear of the tractor but possibly could be optioned for dual pto . Anyone know of a side seat L , PL twenty with a dual pto for me to team it up with😆 . Hopefully we can find the missing parts or match them up with something a little more common . How many sizes of planers did cat produce ?
Thank you Erick , you are a big help !

to my knowledge caterpillar only had the 20 planer which of course was pulled by a twenty!
Russell made a planer as well but when cat took over in 1928 the motor patrol and early motor grader replaced the planer.

I second that Moulding, he's an asset to the club, and I appreciate all he does to gather and share information - there are many fellows in the club that do so and it enriches us all : )

Hi Team,
I have a blue covered Twenty Planer Parts Book here (Not For Sale) :- Form No P-627 (2500-4-31) do not know what the numbers in the brackets are but may be Russell?

It covers machine numbers N-1 to N-310 Incl. The N-310 Incl. is printed with a rubber ink stamp.

Cat often allocated Serial Number blocks for machines, but often did not actually build that many.
Cheers,
Eddie B.
