Pro-Lok in Detail
Pro-Lok® is a class leading, safe, mechanical quick coupler with double locking technology and built-in safety features putting operator safety at the forefront. Simple to attach, easy to operate and super low maintenance. This manual quick hitch picks up all your buckets and will outperform and outlive any spring-type equivalent many time over.
