Wow. never saw this until it got bumped. Really great detective work.
TeeGate said:If you do a search here you can find more, and maybe even the photo's of the harvest that I posted. But basically here is what I found:
The Swamp Monster was manufactured by the "Unit" Crane and Shovel
Corporation of Waukesha (Milwaukee) Wisconsin, with offices or
manufacturing plants in other cities. They produced several different
models with different attachments on each one. Some were shovels, some
were cranes, and there is an attachment with a magnet to move around
scrap metal. So which particular model is ours?
In order to find that out, I took a photo of the serial number on a
recent visit there, and started asking questions. Here is what I have found.
Up until 1946, Unit used a common number system for all of their
equipment, with the last piece made that year being serial number 2663.
In 1947 they started using the last two digits of the year of completion
as the serial number prefix, which then would be followed by the
quantity number of the piece made to date. Here is the serial number of
the Monster:
Link does not work anymore. Sorry.

So given that number is 51802, we now know that it was produced in 1951.
I also learned that more than likely, it was built in November or
December of that year because the 802 is slightly less than the machines
built that year. I have not found out how many were actually built that
year.
I also learned that the two model numbers were the 514 and the 614, but
I have not learned as of yet how that is determined. But from the
photo's I have of it there is a clear consensus that it is a 614 which
has a capacity of 5/8 of a yard. I would then assume that the 514 was
the smaller one, with a capacity of 1/2 yards, and the size determines
the model.
Most of these units had the cab set a few feet above the deck gear hood
which made for good visibility.

I have a timeline on when the Swamp Monster was abandoned, and it was much later than I had thought it might have been. In April and July of 1977 there were serious fires in the pines, with one being east of Paradise Lake in the Great Swamp which burned for a week. Many of the cedars still in good condition fell over because the fires burned under the ground and destroyed the roots. Steve (Behr655) noticed the downed trees in aerial photo’s, and members of PBX visited there in our “Shiver Me Timbers and Blow Me Down” Hike in 2006 that you can read about in this thread.
The area in question.

About 120 acres were then put up for bit to have the cedars removed. The contract was won by Paul Harmanson who owned a saw mill in Mt. Holly. He hired Leon Stevens who owned Stevens Landscaping in Sickerville to harvest the trees, with the state receiving $54.320 for the wood. It was decided that because of the harsh terrain, the wood would be cut, placed on sleds, and pulled to dry ground with .......... a bulldozer. Sound familiar! Harvesting began in the fall of 1977, but complications caused them to stop. (Hmmmm) It resumed in January of 1979.
This was slow and costly, so a new plan was devised where a helicopter would remove the wood in place of driving it out. It was estimated that the vehicles could remove 60 cords a week, and the helicopter could do that in one day. The helicopter flew out of Hammonton airport each day of the operation.
All of the cedars removed were dead trees, and all the live tree’s were not touched. To insure the proper trees were removed, a blue line was painted on the tree’s at the division line between dead and live tree’s. This photo illustrates that perfectly.
It is apparent from this info the reason why there are so many downed tree’s still there, is because even though these tree’s fell in the fire because the roots were damaged, they must have still been alive and were not up for harvesting. You can see them clearly here as Steve noticed when planning the hike.

Using the helicopter caused some hazards, especially where occasionally a log would let loose. Everyone would run for cover as to not be crushed by it. One worker from the 15 man shift was injured by a chainsaw, and was airlifted by the helicopter to the lawn of Kessler Memorial Hospital in Hammonton for medical help.
They averaged about 5 acres per week, and the process was expected to be finished by the fall of 1979. Some of the wood had started to rot requiring them to get it done quickly. In the end the wood was worth over one million dollars with you and I getting $54,320 of it.

Armed with the Interstate Commerce Commission accident report, 5 of us headed down the tracks to see what if anything we could find.
