The easy and convenient retractability of the scarifier shanks on the MR1572 makes them highly productive and ideal for ripping, leveling, finish grading, and backfilling applications at commercial feedlots, outdoor arenas, building sites, and maintenance operations on farm and ranch lanes or roadways or constructions sites. The roll-formed moldboard keeps materials flowing which puts less drag on the Box Scraper, resulting in lower HP requirements and faster working conditions.
MR1572 is set up with a mechanical lever to raise and lower the shanks. (Always make sure the scraper is off the ground before adjusting shanks.)
To lower the shanks, pull lever towards unit to release lock pin and move lever away from unit until shank locks into desired position. To raise the shanks, pull lever towards the unit to release lock pin and move lever toward unit until shank locks into desired position.
HR2572, HR3584 and HRL3572 is set up to hydraulically raise and lower the shanks. (Always make sure the scraper is off the ground before adjusting shanks.)
To lower shanks retract hydraulic cylinder, and to raise shanks extend hydraulic cylinder.
