1.) Lay Moldboard on its face with ribbing up. To prevent paint damage place cardboard under top bend.
2.) If assembling a 5' to 7' Moldboard skip to Step #3. If assembling a 7-1/2' or 8' Moldboard, locate four Mold-
board Spring Mount Brackets, two left (1TBP133L) and two right (1TBP133R). Refer to Figure 1.
Moldboard Spring Mount Brackets must be installed with Spring Mounting Tab pointing towards the outside of
Moldboard. Refer to Figure 3.
Mount each Moldboard Spring Mount Bracket using three 3/8"-16 x 1-1/4" Gr.8 Bolts (1TBP25), six Flat
Washers (supplied) and three Nylon Locknuts (1TBP36). Torque all Bolts to 30 ft./lbs.
3.) Assemble Trip Frame (1TBP22B) to Moldboard using four 1" x 4" Clevis Pins (1TBP23) and secure each with
a 3/16" Cotter Pin (1TBP24). Refer to Figure 4.
When installing Clevis Pins, work from Left to Right. Refer to Figure 4 for correct orientation of Clevis Pins
before installing. All Clevis Pins should be installed pointing towards the A-Frame. Tap with Hammer or Mallet
if needed to ease installation.
4.) The F.E.L.B. has been designed with adjustable trip performance. Two Trip Spring mounting holes are
located on all three Trip Frame Spring Mounting Tabs, one Upper and one Lower. Refer to Figure 6.
The Upper Spring mounting holes will give a lighter trip when encountering an obstacle.
The Lower Spring mounting holes will give a heavier trip when encountering an obstacle.
4a. Thread one 5/8"-11 Jam Nut (SN-MK1307) half way onto each of the four Spring Eyebolts (1TBP34).
4b. Insert Trip Spring (1TBP33) end into hole on Spring Eyebolt, then insert each Spring Eyebolt into hole in
Moldboard Spring Mounting Bracket (orient Trip Springs as shown in Figure 5). Thread one 5/8" Nylon
Locknut (1TBP36) onto each of the Spring Eye Bolts.
4c. Tighten the Nylon Locknuts until Trip Springs are taught. Do not overtighten Trip Springs when installing.
Fully tighten Jam Nuts.
4d. Install supplied orange plastic End Caps to Spring Eyebolt ends to prevent corrosion.
5.) Install Blade Markers (1TBP37) to Moldboard ends using supplied 5/16" Hardware. Refer to Figure 7.

7.) Locate both 10" Angle Cylinders (1TBP27) and mount one to each side of the A-Frame. The Angle Cylinders
will be inserted into the A-Frame at the front through the slots, with the Hydraulic Port facing up and visible
through the opening at the top of the A-Frame. Mount each Angle Cylinder to the A-Frame with a 1" x 3" Clevis
Pin (1TBP73) and secure each Clevis Pin with a 3/16" x 1-1/2" Cotter Pin (1TBP24). Refer to Figure 8.
8.) Lift the A-Frame above the Trip Frame, and insert the A-frame and Angle Cylinders into the Trip Frame.
Apply grease to the 1"-8 x 6" Gr.5 Center Bolt (1TBP25) and insert through the Trip Frame and A-Frame.
Secure the Center Bolt with a 1" Nylon Lock Nut (1TBP26). Refer to Figure 9.
Do not over tighten the Nylon Lock Nut, the A-Frame must pivot freely.
9.) Swing A-Frame to Left or Right and align hole in Angle Cylinder Ram with the corresponding hole in Trip
Frame. Install (1) 1" x 4" Clevis Pin (1TBP23) through Trip Frame and Angle Cylinder Ram.
Secure Clevis Pin with (1) 3/16" x 1-1/2" Cotter Pin (1TBP24). Swing A-Frame to opposite side and
repeat alignment and pinning procedure. Swing A-Frame back to the center.
It may be necessary to extend the Angle Cylinder Piston Rod 1-2" to make
the connection to the Trip Frame. To do this, insert a long pin or ratchet handle
through the Piston Rod and work the piston Rod side to side while pushing downward.
10.) Return the A-Frame to the center position after the Angle Cylinders are secured to the Moldboard.
Using the A-Frame as a lever, grasp the A-Frame by the cross-brace and pull back, raising the Moldboard
to a vertical position.

11.) Locate and install the two Hydraulic Hoses (1TBP72) to each side of the By-Pass Relief Valve and to the
corresponding Ports on the Left and Right Angle Cylinders.
Do not use Teon Tape on the Hydraulic Fittings as it may contaminate the Hydraulic
System causing a malfunction. Use a high quality paste type thread sealant on all N.P.T.
ttings.
Due to the large number of variations in tractor hydraulic systems and ttings, two hoses
with 1/4" male NPT threads have been provided to connect between the tractor and
By-Pass Valve, but ttings and quick connectors have not. Most skid steer loaders
have extra lines which can be tied into. Some tractors have an auxillary valve that can be
used, or an optional valve kit can be purchased from Curtis. The last option is to connect
the lines from the loader tilt cylinders and tie them into the bypass block. Be sure to
connect before the T-Fitting that connects the left and right tilt cylinders. If using this
option the loader blade will need to be supported with Lift Chain provided. See Step 12
below.
12.) Attach Lift Chain (1TBP30A) to A-Frame assembly with 5/16" Anchor Shackle (1TBP31).

Mounting F.E.L.B. with Loader Attachment Brackets
1.) Center A-Frame (1TBP29A) in front of the Tractor. Position one or both Loader Brackets (1TBP170) to align
with each of the Tractor Loader Arms, depending on width. Refer to Figure 12.
2.) Fully seat the tongue and groove cutouts of the L & R Loader Brackets into A-Frame Rear Cross Brace.
Position L & R Loader Brackets so that the outboard bracket bolt holes line up with
slots in Rear A-Frame Cross-Brace. This may result in two of the same bracket on each
Loader Arm depending on Loader Arm width.
3.) Verify 1/8" clearance on either side of Tractor Loader Arms. Attach the outboard L& R Loader Brackets
to A-Frame Rear Cross Brace by bolting through the slots in the A-Frame. Use 1/2" x 1-3/4" Bolts in top of
A-Frame (2 per bracket). Use 1-1/2" length Bolts in all other holes (3 per Bracket).
Install 1-1/2" Bolt through front of A-Frame Cross Brace rst.
4.) Position inboard Brackets with a 1/8" clearance and clamp in place. Drill 9/16" holes into the A-Frame Cross-
Brace using the holes in the Loader Brackets as guides. Bolt inboard Brackets to A-Frame Rear Cross Brace
with 1/2" x 1-3/4" Bolts in the top of the A-Frame (2 per Bracket) and 1-1/2" length Bolts in all other holes.
Torque all Loader Bracket Bolts to 98 ft./lbs.
• Loader Brackets L & R are to be bolted to the A-Frame in accordance with the I.D. and
O.D. of Loader Arms. Tongue and Groove design allows installer to slide Brackets into
position. Leave 1/8" clearance for Easy On/Easy Off.
• Due to Tractor Loader Arm variations, Dealer/Customer is to supply Attachment Pins.
Curtis recommends a Grade 8 Bolt and Nylon Locknut of the proper length and diameter.
After 2 hours of use, all bolted assemblies on the F.E.L.B. should be rechecked for
proper torque specications and tightened as needed.
