According to the manufacturer, the Rapid Tach II quick-coupling system is the only such device approved to work with LaBounty mechanical attachments such as concrete pulverizers, bucket linkage shears and mobile wood shears. It also works with buckets, compactors and hammers. The coupler allows attachments to work with virtually no loss of power, compared to pin-on versions. Couplers are available for machines with a base weight of 30,000 to 100,000 pounds.
