OPTIONAL ACCESSORY
1° CHECK CHAIN KIT (No. 108 6530) (photo 25)
These chains may be recommended when operating with certain tractors with older style hydraulics which would
not allow a steady swivel head ground clearance to be maintained during work. They also help prevent the PTO
shaft from bottoming out should the lift linkage be lowered accidentally.
To install chains proceed as follows :
- Connect the tractor lower link arms to the hitch brackets (C) (see section Attachment of the machine).
- Raise the tractor hydraulic linkage until the swivel head lower links clear the ground by approx. 800 mm / 31".
- Attach one end of chains to hitch brackets (C) with D-hangers (H) and their other end to the tractor top link pin.
- Completely lower the tractor linkage. Height adjustment is correct when :
. lower link arms (T) are level,
. chains are tight,
. distance (A) between hitch pins and ground is 750 mm / 30" .
