An adjustable toe board, an adjustable toe board assembly, kit and sawmill comprising the adjustable toe board are provided. The toe board comprises a baseplate having a first end, an opposed second end, and a rod extending away from the baseplate. The toe board includes a support bar pivotably coupled to the baseplate proximate the first end, spaced apart from the rod, and extending towards the second end, the support bar being configured to support a log. The toe board also includes a ratcheting arm pivotably coupled to the support bar, the ratcheting arm having a plurality of spaced-apart teeth defining notches adapted and positioned to selectively engage with the rod, wherein selective engagement of the teeth with the rod enables pivotal adjustment and releasable locking of the support bar relative to the baseplate during operation.
