CAUTION!

Use 

FLASHING WARNING LIGHTS 

when traveling on public roads day or night,

unless prohibited by law.

Transport Light Kit

If the rotary cutter obscures the tractor warning or tail lights, the rotary cutter 

MUST 

be equipped with a transport

light kit.

Check local highway regulations concerning moving machinery on highways.

Installation of Lights

Secure the cutter into transport position. Mount the brackets to the center beam as shown in the illustration, using
the supplied 3/8" U-bolts. The two 4" x 4-3/4" U-bolts are needed for the TWR-180/TWR-120 kit, and the two 5" x
6" U-bolts can be discarded.

Align the outside edge of the brackets with the end caps on either side of the beam. Tighten into place. Using the
5/16" bolts, mount the lights to the brackets with the red and amber lenses facing to the rear, and the amber in the
outer-most left and right positions. When the cutter is in transport position, the light assemblies should be sitting
vertical on the center beam.

Wiring Harness

The seven pin plug and wiring harness is pre-wired with the 7' leg to attach to the left hand light assembly and the
4' leg to attach to the right hand light assembly. Left and right hand is determined by standing at the rear of the
cutter looking in the direction of normal forward travel. The wiring harness plugs are colored coded for connection
to the appropriately colored lamp.

Using the cable ties, route the harness along the hydraulic hoses to the front of the cutter Allow enough slack in
the harness for the up and down movement wings. There should be approximately 5' to 6' of harness extending
past the hitch point for connection to the tractor.

Circuit Testing

The seven pin plug is wired as follows:

The lights should operate in unison with your
tractor lights.

Terminal 1 Ground
Terminal 3 LH Turn & Flash
Terminal 5 RH Turn & Flash
Terminal 6 Tail Lamps
