INTRODUCTION
DESCRIPTION
The sturdy CB420 cab is carefully designed to fit the model 420 and 430 tractor equipped with a
ROPS rollbar. It is extremely useful in cold weather when operating a snowblower, V-blade, or a power
angle blade. Exceptional features include ease of entry from either side, full glass windshield and back
window, and lightweight removable doors. Supported by the ROPS rollbar and equipped with a seat belt,
the operator has added comfort and safety protection. There are a few limitations, however, with the cab
installed. Overall visibility is good, but portions of the cab create blind spots.
A windshield wiper is standard equipment. Additional lights and safety lights may be added as desired by
the owner.
NOTE: The CB420 cab cannot be used with the front end loader, vertical auger or boom mower
attachments when the mounting shaft is in place.

5/16 X 1" bolts through the frame and
treadplate. Next, bolt the top of the front panel
to the front of the roof panel as shown.
8. Bolt the four hinges to the rear panel with (8)
5/16 X 3/4" bolts as shown in Photo 3.

time. Install weatherstrip around the door
opening along the top and front sides as shown
in Photo 3.

ASSEMBLY INSTRUCTIONS
11. From the left side of the tractor, install the “S”
hook on the top edge of the pump mount plate
as shown in Drawing C.
12. Stretch each top elastic cord from the fabric
panel across the front panel to the extended
bolts. Pull the middle elastic cord through the
tractor above the drive shaft. Loop the elastic
cord over the “S” hook to prevent rubbing the
driveshaft. Take the bottom elastic cord through
to the other side in front of the frame pivot as
shown Photo 4.
13. Mount the wiper above the windshield according
to the wiper instructions. Mount the wiper blade
on the wiper arm with the short end of the blade
away from the wiper motor. Check the wiper
blade path so that it does not contact the rubber
moulding. Fasten the inline fuse to the auxiliary
side of the circuit breaker and route the wire to
the wiper.
14. On Kubota engine models, install the air intake
tube guard on the left rear of the black side
panel. The guard bolts to the same holes that
the side panel does and uses the existing
hardware. The guard is to prevent the cab
fabric from plugging the air intake tube and
stalling the engine.

WWF WINDSHIELD WIPER INSTALLATION
(Except 1000 Series)
1. Locate mounting position of wiper assembly.
2. Determine whether adequate space is
available.
3. Locate approximate stud position on header.
See that blade will wipe the desired area of
windshield.
4. Should a change of wiping angle be needed:
a. Remove gear case cover.
b. Remove spring clip on pivot shaft arm.
c. Lift link and install in desired degrees on
gear.
d. Reverse the above procedure to
reassemble.
Wiping angles available are 85, 100, 110, and 120
degrees.
5. Distance between stud hole and bracket hole
should be 6.25 inches.
6. Drill tower stud hole first using a 5/8" drill.
7. Drill mounting bracket hole for a No. 10 screw.
8. Place the wiper in position and install the
mounting stud attaching nut and washers.
Tighten to 30-50 in. lbs.
9. Wiring - See diagram. On applications where
mounting is of wood, fiber, glass etc., a separate
ground wire must be attached to the motor and
connected to a battery ground point. A no.14
wire is recommended.
NOTE: Blade and arm should be mounted
approximately 1" minimum away from windshield
molding. Make certain the wiper blade does not
strike at either end of the wiping stroke. If blade
strikes at both ends, it will be necessary to shorten
the arm and blade length or reduce the wiping angle
of the wiper. (Refer to Step 4.)
