ABSTRACT:
A disc mower incorporates a modular disc cutterbar. The drive mechanism for the mower utilizes a V-belt drive apparatus that requires proper tensioning which is accomplished through a spring tensioning mechanism that includes an indicator to visually determine when the proper tension has been applied. The indicator includes a bracket positioned adjacent the spring and has a length substantially equal to the length of the spring required for exerting the proper spring force for tensioning the drive belt.
