26 Assembly
WPMAN0142 (Rev. 9/1/2004)
ASSEMBLY
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
Before working underneath, raise mower to
highest position and block securely. Blocking up
prevents mower dropping due to hydraulic leak
down, hydraulic system failures, or mechanical
component failures.
DEALER SET-UP INSTRUCTIONS
Assembly of the mower is the responsibility of the
Frontier dealer. It should be delivered to the owner
completely assembled, lubricated, and adjusted for
normal conditions.
Complete the checklists on page 30 when assembly is
complete.
IMPORTANT
Gearbox was not filled at factory. It must be ser-
viced before operating mower. Failure to service
will result in damage to the gearbox. See page 29.
The mower is shipped partially assembled. Assembly
will be easier if the components are aligned and loosely
assembled before tightening hardware. Recommended
torque values for hardware are located on page 41.
Select a suitable working area. Open parts boxes and
lay out parts and hardware to make location easy.
Refer to illustrations, accompanying text, parts lists and
exploded view drawings.
