Old iron. New purpose. Still getting the job done.

Out in Montana at Live Oak Belgians, LLC this classic roller is back to work—pulled the old-school way and proving that good equipment never quits.

The fix - they cut an access hatch on the side to fix an interior part that was broken and rattling, and straightened a rear frame bar.

The modification - they installed an adjustable ice/snow scraper to the front frame bar.

Whether it’s 50 years old or fresh off the lot, if it works, it works.

At Arnold’s, we keep equipment like this rolling with the parts, fabrication, to make it last another generation.

Got something old doing a new job? We’d love to see it.

Thanks Live Oak Belgians, LLC for sharing your update!
