Nope,
Euclid/Terex used an unusual alpha-numeric numbering system to identify their stuff.
For an example, a TS-14 might be listed as a type 13UOT-61SH
Broken down this means:
Model: 13
Fifteen Ton axle: U
Overhung (single axle tractor): O
Tractor: T
Model: 61
Scraper: S
Hydraulic: H
The machines shown in the photos are probably model LDT's, not TDT's or FDT's
Oh I see. Can they replace scrapers when it comes to spreading material?
