ASSEMBLY
GENERAL INSTRUCTIONS
To assemble your new INTERSTATER and mount it to your tractor we assist you with drawings, instructions
and information, also about experiences of others and when needed just get some information or clarification
from our engineering department over the phone.
These instructions are general information and not specifically for your tractor, but in connection with our
drawings, they might offer your some valuable assistance.
This section covers the installation procedure of an Alamo Group Interstater mower kit, and includes parts lists
for framework, hoses, and miscellaneous parts to be attached to your tractor.
These instructions are for mounting the center mower, right side mower, and left side mower units. For
mounting one mower side only, disregard information concerning the opposite side. Hardware quantities
shown are for both sides.
1. The hydraulic system must be kept “SURGICALLY CLEAN” to ensure proper operation and long life of the
pumps, motors, and valves. All components have protective caps over openings connected to internal
spaces to prevent contamination. It is important that care be taken during unpacking, assembly, and other
contaminants which will damage parts.
2. After the drive belts are installed, DO NOT start the tractor unless the hydraulic system is filled with
hydraulic oil. Running without oil will damage the pumps.
3. Check the oil level in the reservoir before start-up.
4. Care should be taken when filling the reservoir to prevent contamination of the hydraulic system. Always
use new hydraulic fluid when filling the system. USE ONLY TRACTOR HYDRAULIC OIL IN THE
HYDRAULIC SYSTEM.Reference to the left or right side of the Interstater is determined while facing the
front of the tractor from the drivers seat.
Reference to the left or right side of the Interstater is determined while facing the front of the tractor from the
drivers seat.
Assemble the Interstater, step by step, as illustrated on the pages of this section. Small parts (bolts, nuts, etc.)
required are packed in numbered plastic bags which correspond to assembly procedures and illustrations in
the manual.
The part quantities listed for an illustration pertain only to that phase of assembly. The quantity given
corresponds to the number of parts needed. When assembling a single-sided model based on a dual-sided
model, the quantity furnished will usually be half the quantity listed.
Large parts are not always listed next to an illustration because they are usually easy to identify.
Whenever reference is made to parts, listed for an illustration or elsewhere in this manual, the following
abbreviations are used:
HHCS - hex head capscrew RH - right hand NF - national fine
LW - lock washer LH - left MA - mechanical assembly
PW- plain washer NC - national coarse WA - welded assembly
When installing fasteners, PW and LW (generally installed in that order) are usually on the side of the fixture or
part being fastened that the hex/lock nut is on. When only HHCS, LW and/or PW are required, they are
generally installed in that order. Some parts do not require a PW or LW. Refer to illustrations for exceptions.
Fasteners should be installed so they cause the least interference with other parts. When securing driveshaft
pulley to hub, tighten fasteners to 9 lb-ft torque.
This manual makes reference to individual component parts, some of which may have been pre assembled at
the factory.
