9. Test drive machine for straight line
travel with both levers full forward. If
travel is not in a straight line, raise the
steering lever stop on the side that is the
fastest i.e.: if machine goes to the left,
raise the right steering stop to slow
down the right transmission until travel
is straight ahead.
8. Reinstall linkage rod in control arm. If
ball stud does not reinstall into control
arm without moving the control arm, ad-
just length of linkage rod until it does to
assure neutral adjustment will be main-
tained when linkage is reconnected.
7. Repeat procedure for other side trans-
mission.
NOTE: Pivot bolt roller Is mounted off
center and works as an eccentric when
the bolt Is turned. Use special wrench
enclosed with operators manual to ed-
just.
1. Block up under tractor frame so both
drive wheels are off the ground.
2. Make sure parking brake is released.
3. Remove linkage rod (item 34) from
transmission control arm (item 23).
4. Place steering levers in the neutral
swing-out position and start engine.
5. If either of the drive wheels turn, pro-
ceed with the following adjustment.
6. Loosen locking nut (item 26) and rotate
pivot bolt (item 25) until neutral is
achieved. Tighten locking nut.
NEUTRAL ADJUSTMENT
(Refer to III.on page 22)
If drive wheels travel forward or reverse
when the steering lever is in swing-out posi-
tion (neutral), adjustment is required.
NO POSITIVE NEUTRAL POSITION
Change filters, one on each transmission,
every 300-500 hours depending on severity
of use; 500 hours under normal mowing
conditions and 300 hours if using a
grasscatcher or if temperatures are above
100 degrees F. To change oil, remove
drain plug from bottom of oil reservoir and
allow reservoir to drain completely. Re-
place plug and tighten. The transmissions
cannot be individually drained. Refill the
reservoir with 2.5 gallons of oil of the type
and viscosity as prescribed in the above
section. Run engine and check for leaks.
Stop engine and check that oil level is be-
tween the two marks on the dipstick.
Note: No air bleeding is necessary, the
system Is self bleeding.
CHANGING GEMINI TRANSMISSION OIL
AND FILTERS
Check oil level with the engine turned off.
Pull dipstick on left side of machine next to
air inlet screen. This is the oil reservoir for
both transmissions. If oil is required, add
until level is between the two marks on the
dipstick. Use Mobil DTE26 (Grasshopper
Part No. 345280 for 1 gallon container).
For severe duty, use Grasshopper Fluid
Part No. 345050 for 1 quart container.
CHECKING GEMINI TRANSMISSION OIL
LEVEL
Check the fluid level and make sure the
proper amount of fluid is in the reservoir.
The cooling fins and fan blades should be
clean and free of foreign matter.
