The standard duty snow pusher is a great price point snow pusher. Standard features include a rubber cutting edge and bolt-on replaceable wear shoes. Ten gauge mouldboard and 1/4” side plates make this a great value for your money attachment for quick snow removal.The extreme duty series is a brutally heavy snow pusher for the serious snow contractor. Extensive reinforcements in the back and thicker wear shoes along with heavier side plates make this snow pusher top in its class.
