A sprung drawbar improves the ride of the trailer and reduces the stress on the tractor
pick-up hitch. It is particularly suitable for large capacity trailers which are
used for hauling loads long distances on the road.
The multi-leaf spring is mounted onto the 20mm thick drawbar base plate using 3 U-bolts.
The top of the drawbar is further strengthened at the pivot at the front of the chassis
by an additional saddle. The front pivot tube complete with phosphor bronze bushes
is set into the top of the drawbar with an easily accessible grease point.
