Scale Bracket and Load Cell Mounting Installation

SCALE BRACKET AND LOAD CELL MOUNTING INSTALLATION

1. With the planter wings folded in, lift one side of the hopper and remove the rear leg support.
Important: The lifting chains, bucket attachment, loader/skid steer or winch must be capable of lifting
and controlling 1000 lbs.

Scale Bracket and Load Cell Mounting Installation

Figure 2. Completed Rear Mount

2. Assemble both the left/right hand rear leg assembly.
Place the CT Load Cell between the top and bottom legs.
Use the 5/8” x 2” bolts on the outside two holes of the
security plates. On the center holes of the security plates,
use the clevis pins to secure the plate. Tighten 5/8” bolts
until the bolt is snug. See Detail C.

3. Replace the rear two legs with the new leg assembly.
Install the new leg assembly with the scissor plates to the
outside of the machine. Reuse the original 5/8-11 bolts,
nuts and U-bolt for installing the top and bottom load cell
weldments. After installing the new leg, loosen the lock
nut on the bolts that hold the security plates together, so
the bolts themselves can be turned by hand. Figure 2
shows a completed Rear Mount.

4. Front Mount Assembly: Remove the bolts to the front load cell bracket and frame. Lift front leg up 3/4” and
install the weigh bar into the sleeve of the front leg. Use the 3/4” x 4” bolt and locknut.

NOTE:

It is important that the load cell arrow, located on the end of the load cell, must be pointed up.
Install the front load cell mount bracket by using the 3/4” x 4” bolt and locknuts.
Let the hopper down and use the existing bolts to hold the end bracket to the frame. Make sure you have

clearance between the main bracket and the frame. The holes are slotted on the end bracket. You may
need to adjust the bracket before tightening bolts.
