摘要:
A heavy duty drawbar features a Z-type brace which is accessible from the end of a vehicle which carries the drawbar. The Z-type brace provides significant strength for the overall drawbar while still allowing easy access to the hitch fastening bolts for easy changing. Also, the hitch can be placed very close to the vehicle when held by such a Z-type brace. Two of the Z-type braces are supported each between generally vertical frame members and the hitch of the drawbar is supported between the two Z-type braces.
