Abstract:
A hitch system comprising a hitch shaft with a forward end configured to rigidly attach to a tow vehicle and a rearward end extending rearwardly toward a trailer frame; a head unit pivotally attached to the rearward end of the hitch shaft at a first pivot point having an upper portion and a lower portion, comprising a hitch ball on the upper portion of the head unit positioned out of vertical alignment with the first pivot point creating a second pivot point between the hitch ball and a trailer attached thereto; and a slot on the lower portion of the head unit, the slot having portions in vertical alignment with the first pivot point and the second pivot point; a first moment arm with a distal end configured for slidable attachment to a first bracket on the trailer frame and a forked proximal end comprising a first tine pivotally connected to the lower portion of the head unit; and a second tine having a knob in a sliding connection with the slot; and a second moment arm with a distal end configured for slidable attachment to a second bracket on the trailer frame and a proximal end pivotally attached to the head unit; wherein the first moment arm is at a first angle relative to the member of trailer and the second moment arm is at a second angle relative to the trailer; wherein the first angle is greater than the second angle; and whereby the effective pivot point of the system is moved forward to reduce sway is disclosed.
