TMZ-34/19
Part No. 52075
Ground Controls
TMZ-34 models manufactured in the 1998 and
1999 model years (from serial number T3498-001
to T3499-769) were originally equipped with
ground controls boxes containing three printed
circuit boards. Machine functions are activated
using push buttons on the exterior of the box.
Beginning with the 2000 model year (from serial
number T3400-001 to date), the ground control box
was changed to a two-board configuration. The
push buttons used to activate machine functions
on earlier models were replaced with a membrane
overlay decal, mounted on the exterior of the box.
