MACHINE ASSEMBLY
GANG ASEMBLY
CAUTION:
Due to the size and awkward nature of the trailing discs it is important that all
components are adequately supported.
As there are a number of sizes of discs available, refer to the attached set-up sheet on the
back page in this manual. It provides approximate measurements to suit your discs.
Adjustments may need to be made to suit different ground conditions.
Both gangs are different so distinguish which is the front and which is the back prior to
assembly. The scrapers are mounted at the rear of each gang.
FRONT GANG:
Position the front gang under the main frame in the approximate position it will be secured in.
Starting with the left hand side (direction of travel), place the front “U” bolt (Pt 3375) over the
main frame side-members, with the thread pointing down. The left hand side front “U” bolt will
be located in front of the main frames’ front cross member. Bring the two frames together and
placing the clamp plate (Pt 3381) under the gang frame, secure with nuts and spring washers.
The front “U” bolt on the right hand side should be placed behind the main frames’ cross
member and the clamp plate secured with nuts and spring washers. Secure the back two “U”
bolts on the front gang in their appropriate positions, making sure that threads always point
downwards.
REAR GANG:
When attaching the rear gang, the simplest way may be to reverse the main frame and front
gang over the rear gang. Alternatively, lift the back of the main frame up and support it whilst
rolling the rear gang into position. Starting with the right hand side, place the rear “U” bolt
approximately 225mm behind the main frame cross member and using the clamp plate secure
the frames with nuts and spring washers. On the left hand side of the rear gang, the rear “U”
bolt should be 610mm from the same cross member and secure using the clamp plates and
nuts and spring washers provided.
DRAWBAR ASSEMBLY
Generally the drawbar runs in the right hand half of the pull bar. For initial set up, position the
drawbar approximately 280mm from the right hand side of the pull bar. Tighten the drawbar
plates (Pt 3388) securely with the four bolts, nuts and spring washers provided. The height
adjustment of the drawbar must be set so it is pulling fairly straight when in the ground.
Therefore the front gang is neither lifting out of the ground nor dipping into the ground. The
correct setting and adjustment may be made to the drawbar by connecting it to either the
bottom or top of the tractor connecting point. Additional height adjustment can be obtained by
turning the drawbar upside down and connecting it at either the top or bottom of the tractor
connecting point. This should only be done if the adjustment has run out on the tension
springs. Should the discs not be travelling straight it may require the drawbar to be
repositioned along the pull bar until the optimum setting is achieved. The parking jack
(optional) can be used to raise the tractor end of the drawbar. If possible allow the tractor
drawbar to float by removing bars or stabiliser chains which will allow the discs to track straight.
