Mowing What is more tippy?

[flusher]

I've seen Fords modified like that...I think they were modified. Might be a specialty built tractor.
Anyway, the PA Dept of Transportation has a bunch of them for mowing along the PA Turnpike.

Makes sense to me. I've seen similar Caltrans tractors mowing some pretty steep inclines around overpasses. Don't know if they're modifieds or special builds.
