SECTION 2 INITIAL SETUP
2.1 Assembly Instructions
Your Articulator requires a minimum amount of assembly
prior to mounting to the tractor. Follow the procedures
listed below to assemble the Articulator:
1.
Mount the pull arms onto the Articulator pull bar.
2.
Orient the arms so that they bend outward as they
extend from the tractor.
NOTE:
The pull arm gussets must be oriented as
shown below.
3.
Install the lift pins into the Articulator pull arms.
The pins locate to the outside of the arms, with the 7/8” split
lock washers and 7/8-14 hex nuts to the inside of the arms.
2.2 Mounting The Articulator To The
Tractor
DANGER!
Before attempting to mount the Articu-
lator to the tractor, ensure the PTO is disengaged,
then engine is off, the parking break set, and the
transmission is in neutral.
The Model 721/521XR Articulator can be mounted to most
tractors which have a category 1 three-point hitch. Follow
the procedures listed below to properly mount the Articula-
tor to the tractor:
1.
Park the tractor on level ground.
2.
Lower the 3-point hitch.
3.
Turn off the tractor, disengage the PTO, shift the trans-
mission into neutral, and set the parking brake.
4.
Remove the key from the ignition.
5.
Mount the Articulator pull arms to the lower arms of the
3-point hitch.
6.
Slide the Articulator lift pins into the ball swivels on the
three-point hitch arms.
7.
Secure with lynch pins.
8.
Adjust the tractor sway bars to eliminate any side-to-
side motion.
9.
Connect the hydraulic hoses to the tractor.
10.
Mount the PTO shaft to the Articulator, then to the trac-
tor.
11.
Secure the PTO guard retaining chains located at each
end of the PTO shaft to the Articulator pull bar and the
tractor.
These prevent the outer guard from turning with the PTO
shaft for safety purposes.
12.
Turn the Articulator as far as it will go in each direction,
and measure the distance between the rear tractor tire
and the Articulator.
13.
Adjust the pull bar stops (located on the front dual
wheel legs) to allow a minimum 2” clearance between
the tractor tire and the Articulator when turning.
a.
Loosen the jam nuts.
b.
Adjust the bolt to stop travel at 2" from the tractor
tire.
