OPERATION________________________________________________________________________________________
1. The vertical mowers operate in forward rotation allowing
each blade tip to break (cut) new turf and therefore
requires more power than normal mowing.
a. Do not operate the vertical mowers when the
hydraulic reel motors are loaded to a point where
they stall or slow down.
b. The operator must adjust the ground speed to
accommodate for the cutting conditions and power
requirements.
c. If the mower slows down under load, it is an
indication that the cut may be too deep.
2. The vertical mowers were designed to mow at depths of
1/8 to 1/4” (3.2 - 6.4 mm) above the roller, depending on
turf conditions and operations being performed. A greater
cutting depth may damage the root structure and
increase power requirements. It is recommended to begin
with a higher setting and gradually lower blades until
desired results are obtained.
a. Grain control (light and frequent operation) - half of
normal cutting height.
d. Thatch removal (every 60 to 90 days) - 1/8” to 1/4”
setting.
e. Renovation (heavy thatch removal) - not
recommended with Tri-King vertical mowers.
3. Vertical mowing is an operation that can create a lot of
dust and debris. Special care must be taken to clean the
air intake system on the Tri-King at regular intervals.
Check the air intake system if the water temperature
gauge (Diesel Units) indicates an elevated temperature
level.
ROLLERS __________________________________________________________________________________________
1. When replacing the bearing (A) the cup and cone should
be replaced in sets. Hand pack each bearing cone with a
good grade of multi purpose Moly 2 EP grease.
2. To remove the bearing cup use a blind hole bearing
puller.
3. When installing the seals (B and C) be sure the lip is
towards the center of the roller.
4. After complete reassembly of the roller tighten locknut (D)
to 10 - 30 ft./lbs. to seat bearings. Readjust locknut to
develop 3 to 7 in./lb. rotational torque resistance on shaft.
Check torque resistance of roller after 25 - 50 hours of
operation and every 250 hours after that.
5. If lubricant inside of roller has been flushed during
disassembly, apply 15 - 20 pumps of multi purpose Moly
2 EP grease with a hand gun into fitting after roller has
been reassembled.
Figure 6
CUTTING DEPTH ADJUSTMENT _______________________________________________________________________
1. To achieve the desired depth of cut, place an adjusting
gauge at either end of the cutting unit across the two
rollers as shown. [Figure 3]
2. Adjust the cutting depth of the blade with the rear
adjusting nuts. For most applications front adjusters
should be positioned with the top bolt passing through the
second hole from bottom as shown. [Figure 7]
a. Turn the end blade so that one tooth of the blade is at
90 degrees to the top of the gauge as shown.
b. The blades should be adjusted to be at the same
depth at both ends of the cutting unit. [within 1/64”
(.4mm) inch]
3. The ground line should be close to parallel with the
bottom of the mower frame to assure proper cutting and
discharge angle. As the blade wears the front adjuster
can be repositioned to allow proper cutting angle and
depth.
Figure 7
CAUTION
To prevent contamination of the engine compartment, do
not operate the mowers in reverse rotation.

ADDING, REMOVING OR REPLACING BLADES ________________________________________________________
1. Blades may be replaced without removing the cutting unit
from the frame.
2. Loosen blade nut (B) from 1/4” to 3/8” (6.3 to 9.5 mm)
towards the frame.
a. Pull spacer (C) next to the blade (D) to be removed
toward the nut to disengage it from the locking lugs
on the spacer.
b. Remove blade from the shaft. Install replacement
blade with the slot in blade in same position as blade
that was removed and retighten nut (B) securely.
(Torque nut to 12-15 ft. lb. (16-20 N.m)
3. Blade spacing can be adjusted for different modes of
operation, from 1/2” (13 mm) to 1-1/2” (32 mm) in 1/4”
increments (6 mm).
a. 1” (25 mm) spacing between blades is the standard
factory setting.
b. 3/4” (19 mm) to 1-1/2” (38 mm) spacing is
recommended for fairways, greens surrounds and
sport fields.
c. 3/4” (19 mm) to 1” (25 m) spacing is recommended
for tee tops.
