853 with a high-flow auxiliary hydraulic pump to power attachments like planers and breakers.
A year after launching the 753, engineers took a cue from others in the industry and designed a multiple linkage lift arm structure and stretched the wheelbase a few inches. The resulting vertical lift path 7753 (later the 773) offered more capacity (1700 lb.) in a similar size loader frame. Because the bucket position remained more or less vertical throughout the lift cycle, the 773 had more lift height and reach, making it more adept at truck loading.
In 1993, the 753L (later the 763) was launched with a wheelbase five inches longer. It retained the 753’s traditional radius path lift arm but provided more lift capacity (1500 lb.) The compact radius 753 remained in the lineup for applications in tight quarters.
