The Cat DIESEL FIFTY

Series 1E1-1E2065, 1933 - 1936

The DIESEL FIFTY was a new model in the lineup.

Like most tractors of the period, the DIESEL FIFTY was made in two versions, narrow 60 inch (see below) and wide 74 inch gauge versions. DIESEL FIFTY was made in small numbers being replaced by the RD7 which was introduced in 1935.
