Champion windshield wiper

After dealing with a non-working windshield wiper on a rainy gravel road, I'm trying to figure out if Champion used a standard HD wiper or if I have to go with an OEM replacement?

Chances are on that old machine you just pull out the rubber blade and put in a new insert. The wiper frame itself stays on the arm.

I need to take a closer look at it to see if it just needs new rubber. Online I found it might use an HD series Trico wiper assembly.

If it's a Trico J hook wiper arm, new wiper assemblies are pretty common.

From what I can tell, it's a metal U-shaped holder with the rubber blade attached. I don't think you can swap out just the rubber part.

Not sure what you mean.

Mine looked the same as what's on my backhoe. I grabbed replacements from Napa and they had different lengths available for older equipment.

I think a Trico HD flat blade should work. I found an auto parts place that stocks them, and Napa has them too though they're not available at the stores nearby. I want to verify it's the right one before ordering though.

The grader has a double arm wiper up front and a single arm on the back. Right now I'm just focused on the front one, but I'm hoping to find a wiper blade that costs less than going through Volvo. It's 20" long.

Double arm flat glass wipers were common on buses and equipment back then. AC Delco still makes them, part number 8-7211.

Looks like the Trico HD 61 series is what I need. Most places only had 18" in stock, but I found a store with 20" at another location and they're transferring it for pickup tomorrow.
