The Peerless SW53 is a 53-foot hayrack platform offered in standard and heavy-duty configurations, so the same footprint covers both ordinary and demanding shortwood work. Air ride suspension with an adjustable king pin setting gives legal-length flexibility across jurisdictions, which matters for operators crossing provincial lines. This is the one forestry model where Peerless publishes real numbers: axle spreads, king pin settings and tire sizes are all specified.
