Severl time we have had discussions about unusual MOW equipment around these FORUMS.
I had started a Thread on the KIROW rail cranes used in the UK and other places in Europe. And recently there was a discussion about some of the equipment Herzog and some of the other Third Party Railroad Maintainance Provider field to resolve specific issues of upkeep for their customers.
While researching another topic I found this site and was intrigued by several of the items listed.
One specifically caugt my eye: A John Deere Gator off road work ATV. There are severl used by farmers in this area and they appear all over for sport and commercial as well as recreational use. The County Sheriff here uses one as a search and rescue vehicle and it is around whenever they do a parade.
This is the linked "GATOR’ that caught my eye/ A hi-rail equipped machine:
