Here's some large Cletrac crawlers. The largest crawlers in their day. Years are approx. 1929 and 1930. Interesting the the 1929 is a very early model. 75 was originally cast in the rad. support but Cletrac discovered it actually had 100 HP so ground the 75 off and screwed 100 numbers on. These both run very well. The rads. are in perfect condition and were like that when the current owner acquired them. The engines are made by Wisconsin. The same Wisconsin famous for their air cooled engines. They are thirsty though. 250 gallons of gas won't last an 8 hour shift.
