Mounting kit can be installed using tools ordinarily
available including an overhead hoist and sling for initial
loader installation, floor jack, standard and metric

Check front tire clearances once loader is installed and
adjust tire track width as necessary.
Reference to left and right used in these instructions
refer to position when seated in the operating position
on tractor.

assembled to facilitate assembly and proper alignment.
Unless otherwise specified, tighten all hardware to
torques specified in General Torque Specifications
table included in loader operator’s manual.
1. Fasten front mounting bracket (1) to front of tractor
frame using 14mm x 40mm cap screws (5) and 9/16"
lock washers (7).
2. Fasten right mid mounting bracket (3) to right side of
tractor frame and casting using 16mm x 45mm cap
screws (4) and 5/8" lock washers (6). Fasten left mid

WARNING: To avoid injury during
installation of quick attach loader, do not
permit bystanders within ten feet of loader.
1. Loop chain under each lift cylinder and hook on
loader boom arm. Using overhead hoist to support
loader remove hardware securing loader to pallet.
Lift loader and remove pallet.
CAUTION: Do not damage grease fitting on
end of cylinder. Be sure chain does not pinch
lift cylinder.
2. Using overhead hoist, lower loader from vertical
shipping position to horizontal position leaving
enough room to install yoke (8) (use cardboard
scraps to protect painted surfaces). Install yoke (8)
using 3/4 x 2-1/2" cap screws (9) and 3/4" lock nuts
(10). Lower loader completely to the ground.
NOTE: Hardware connecting yoke to loader side
frames should be snug but do not torque completely.
After loader has been mounted to tractor and aligned
with mid mounting brackets and front mounting
brackets, torque hardware to 239-262 ft. lb.

around yoke near loader side frames at balance
point of loader.
5. Using overhead hoist, raise loader until side frame
uprights will clear front tires. Remove lock nut and
washer from loader hinge and swing each hinge
open.
6. Position loader so hinges hook over mid mounting
tubes. Lift front of loader allowing yoke tube to
contact top flange of front bracket. Slide loader
rearward until yoke tube fits inside front mounting
bracket.
7. Clamp hinges to mid mounting tubes with 3/4" flat
washers and 3/4" flex-lock nuts (supplied with
loader).
IMPORTANT: Be sure to use flex-lock nuts to clamp
hinge. Tighten flex-lock nuts against hinge securely,
but not to more than 125 ft.-lb. torque.
INSTALLING BUCKET
Refer to instruction sheet for instructions on installing
bucket.
INSTALLING BUCKET LEVEL INDICATOR
1. Attach indicator guide tube to cylinder pin. Guide
tube is positioned to outside of boom.
2. Slide bucket level indicator rod through guide tube.
Attach other end of rod with 1/8 x 1" cotter pins and
3/8" flat washers.
3. Locate tractor and loader on level surface. With
bottom of bucket resting on surface, cut off excess
rod flush with end of guide tube or paint exposed rod
a contrasting color.
FINAL ASSEMBLY
1. Torque hardware securing front yoke to side frames
to 239-262 ft. lb.
2. Adjust front wheel tread settings or steering stops, if
