16. FEATURE
The D750-LA, D850-LA-1, D950-LA (Mechanical Transmis-
sion type) and D850-LA-H, D950-LA-H (HST type) are
vertical, watercooled, 4-cycle diesel engines. They are incor-
porated KUBOTA's foremost technologies. With KUBOTA's
spherical combustion chamber, well-known Bosch K type
injection pump and well-balanced designs, they feature
greater power, low fuel consumption, little vibration and
quiet operation.
