Abstract
A tamper bar mechanism includes a drive shaft with an eccentric section on the shaft. A tamper drive member is driven by the eccentric section and drives a tamper bar between an upper position and a lower position to define a tamper stroke length. A stroke adjustment link is operatively connected to the tamper drive member and a stroke adjustment mechanism is operatively connected to the stroke adjustment link to adjust an angular orientation of the stroke adjustment link relative to the path of travel of the tamper bar and adjust a length of the tamper stroke length. A paving machine and a method of adjusting the tamper stroke length are also provided.
