Posted by Brian Decatur co. Ia on March 07, 2007 at 17:23:11 from (12.216.134.244):

Some time ago the live pto question was brought up. I read in Herb Morrell's book that the first 300 Oliver 88's were on the dealer's lots before Cockshutt had a live pto tractor available. Here's what I found by nosing through my copy of Nebraska Tractor tests. The Cockshutt 30 was test 382 tested May 21 to June 3 '47 and says nothing about having a live pto. The Oliver 88 row crop with the old "Streamline" tin like the 60 and 70 tractors is test 388. Herb Morrell says the first run of 300 were developed and built this way to draw less attention from spies for the competition. The pictures in the book are very clear. 88 numbers on the old style tin. No mention is made about the live pto that all 88's have. Test 442 is the Cockshutt 40 tested June 12 to the 17th 1950. It is noted as the first tractor tested at Nebraska with live pto. Test 440 is the WD Allis. It has a variant of live pto since all WD's had a trans clutch. Since the 66 and 77 Oliver's were tested before the Cockshutt 40, it's a fair statement that the 40 wasn't the first live pto tractor tested. So my question is, does the Cockshutt 30 have a live pto? I've never seen one so I don't know. I do know that according to Herb Morrell who claims to have designed the live pto on the 88 tractor Nebraska tested did have live pto. I know there is a Hart-Parr that had a pto that was an add on that just happened to be a live type. The other question is when were the 30 and 88 produced? Morrell says the 88 was available first. So....?

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o ... [Read Article]
