A self propelled concrete saw compensates for blade cutting resistance, for example by adjusting a movable drive assembly. An actuator may be used to move the drive assembly, for example through the operation of a control switch by an operator.

Track drive adjustment for a concrete saw

A pavement treatment apparatus, for example a concrete saw, includes a bias element for biasing one part of the apparatus toward another part of the apparatus. The bias element may be one or more springs extending between an engine platform and a handle assembly.

Assist for raise lower mechanism for a concrete saw

A handle support and adjustment assembly for a saw allows the handle to be adjusted in length and/or angle relative to the saw.

Concrete saw handle bars

A bladeshaft assembly for a cutting saw includes a hollow tubular housing member. A shaft member extends coaxially through the tubular housing member and has at least one end that extends outwardly of the tubular housing member. At least one bearing member is disposed in surrounding relation to a portion of the shaft member. A seal is provided for sealing around the at least one end of the shaft member. A pulley member is mounted on the at least one end of the shaft member that extends outwardly of the tubular housing member. A tapered fit is formed cooperatively between the pulley member and the end of the shaft member so as to enable a press fit relation between the pulley member and the end of the shaft member. Additionally, first and second gauge points are formed respectively between the pulley member and the at least one end of said shaft member; the first and second gauge points engaging one another so as to establish a predetermined placement of the pulley member on the end of the shaft member.
