Endcap Assembly
Assemble endcap at the ground level. Attach the endplate to the endcap using 1/4” x 1/2”serrated ange hex
bolts and 1/4” serrated ange hex nuts. Tighten the hardware once nished.

NOTE: If you are installing the optional Electric Roll Tarp skip to Tightening Lip on pg. 5.
NOTE: All Leaner models have (2) hanger brackets. Center the hanger brackets with the rear runners and place the bracket as low as possible on the rear wall.

Drag Cart Series
Place the hanger bracket with the four hole pattern, positioned at the top, in the center of the rear wall on the cart. Keep the hanger bracket as low as
possible on the rear wall. Mark the four holes then drill with a 7/16” bit. See gure bellow for specic model. For 1312, 1326, and 1522 models, the spring
return in the rear of the cart will obstruct where the hanger brackets are supposed to be installed. Instead use a bent hanger bracket (JM0048492 ) and
install directly under the sideboard at the top of the angled shell.

Hanger Bracket
Standard Grain Carts
Install the roll tarp hanger bracket. Use (4) 3/8”-16 x 1”Gr5 Z serrated ange hex bolts and (4) 3/8”-16 Gr5 Z serrated ange hex
nuts to attach the hanger bracket to the rear end panel brace. Tighten the hardware once installed.
Next install the hanger bracket hook and the rubber ap. Use a 1/2”-13 x 1-1/4” Gr5 Z hex bolt and a 1/2”-13 x 1-1/4”Gr5 Z centerlock
hex nut to attach the hook and ap to the hanger bracket. Tighten the hardware once installed.
Note: Make sure that hanger bracket hook is facing towards the cart when installed.
International Grain Carts
Install the roll tarp hanger bracket. Use (4) M10-1.5 x 25 Gr8.8 YZ serrated ange hex bolts and (4) M10-1.5 Gr8.8 YZ serrated ange
hex nuts to attach the hanger bracket to the rear end panel brace. Tighten the hardware once installed.
Next install the hanger bracket hook and the rubber ap. Use a M12-1.75 x 50 Gr8.8 YZ hex bolt and a M12-1.75 Gr8.8 YZ nylon lock-
ing hex nut to attach the hook and ap to the hanger bracket. Tighten the hardware once installed.
Note: Make sure that hanger bracket hook is facing towards the cart when installed.
Center the tightening lip from the front to the rear of the cart on the opposite auger side of the grain cart. Depending on the
length of your grain cart, there maybe a total of two tightening lips. If there is two, position the inside edge of each tightening lip
to the center of the grain cart. Make sure that the tightening lip is ush to the inside of the sideboard. The holes may already be
pre-drilled for installation or they may need to be drilled out with a 1/4” drill bit. Use a pair of C-clamp vise grips to temporarily
hold the tightening lip in place. Bolts will be installed in a later step.

Installing the Rear Endcap
Place the Rear Endcap Assembly onto the back of the grain cart. Slide the endcap to the right until it makes contact with the corner
bracket.
Using a 1/4” drill bit, drill through the hole closest to the corner bracket. Once drilled, fasten with a 1/4” x 1/2” serrated ange hex
bolt and nut. Now drill the opposite side and fasten with a 1/4”x 1/2” hex bolt and serrated ange nut.
Now drill the remaining holes for the rear endcap. All the holes that need drilled run horizontally with the hole that was just
drilled.
NOTE: While drilling, pull up on the front of the endcap
so the faceplate will lie parallel with the rear grain cart
wall.
Sideboard Corner
Note: While drilling, pull up on the front of the endcap so the faceplate will lie parallel with the rear grain cart
wall.
Place 1/4”x 1/2” hex bolts and serrated ange nuts in the remaining holes and tighten the hardware once nished.

Rear Endcap Support Brace
Install the endcap brace. The purpose of the endcap brace is to hold the inside of the endcap up approximately 1” higher than the
outside of the endcap. Drill a hole using a 1/4”drill bit rst followed by a 7/16” drill bit. The hole should be placed onto the nearest
crossbrace which is welded to the shell body. The hole should be located somewhere between the middle of the endcap and the
inside of the endcap. To accomodate for height adjustment, two braces will be used to support the endcap. Use the combination
that raises the inside lip of the endcap 1”above the outside edge of the endcap. Use 3/8” x 1” serrated ange hex bolts and nuts to
attach the braces to the grain cart.

Tightening Rear Endcap
Pull the tightening lip tight against the opposite auger side of the grain cart. Using a 1/4” bit, drill through the hole on the top of
the endcap. Fasten the endcap by using a 1/4” x 1-1/2” bolt and 1/4” serrated ange nut. Tighten the bolt. Now go to the other end
of the endcap and repeat the same procedure.
Now place (3) 3/8”J-bolts into the three holes closest to the auger side in the rear endcap. Fasten the J-bolts with (3)
3/8” locknuts. Use the plastic 3/8” ribbed push in rivet to plug the remaining hole. Leaner carts use four J-bolts and
wont require a ribbed push in rivet.

Installing the Front Endcap
Install the front endcap assembly using the same procedure used to install the rear endcap assembly. Do not forget the endcap
brace. (See pages 6-8) On the front faceplate, use the plastic 3/8” ribbed push in rivets to ll the four 3/8” holes.
NOTE: If your tightening lip is centered and there are no holes visible through your lip lock and sideboard, holes
will need to be drilled wherever there are slots in the lip lock. Use a 1/4” drill bit to accomplish this. Now make sure that
all of the tarp bows are perpendicular to the auger side of the cart and drill 1/4” holes through the sideboards. This should
only be the case on later model grain carts.
Installing Tarp Bows
Install all of the tarp bows. Use (4) 1/4”x 3” hex bolts and (4) 1/4” serrated ange nuts for each bow.
10
Installing Cable Clamps
NOTE: Make sure that the base of the clip bears on the live end of the rope and the “U” of the
bolt bears on the dead end.
Now thread all three cables through the front endcap pulling the end without the cable clamps through rst.
NOTE: Make sure to pull from front to back.
Next guide the cables over the arched bows and thread them through the existing holes on the rear endcap. Now feed the
cables through the cable clamps.
NOTE: Make sure that the base of the clip bears on the live end of the rope and the “U” of the
bolt bears on the dead end.
Place the loop into the J-bolt. Use a vise grip to pull on the cable. Pull the cable tight. To remove all slack from the cable, aggres-
sively tap the cable while applying tension with the vise grips. Then tighten the cable clamp. Once the clamps are tightened,
tighten the J-bolts. Insert a wrench into the hook of the J-bolt and tighten the nut.
Live End
Dead End
Use wrench or bolt to hold the J-bolt while tightening.
Using a cable clamp, feed one end of the cable through the cable clamp, make a small loop, then tighten the cable. Do this with all three cables.
