TYM 4820c
Hello, I have a 2023 TYM 4820C.
I've removed the loader and am trying to hook up a front mount snowblower.
I'd like to use the loader hydraulic controls to control the blower.

But, I cannot seem to be able to figure out what size the quick disconnect fittings are.
Can anyone tell me what size these fittings are?

Thank you

Google these numbers and you'll find a vendor:
V77400106013/8 MALE COUPLER(BSP) (800500003)
164953010003/8 FEMALE COUPLER (800500002)


The first number is the TYM part number,

Are those a special size? The 3/8 couplers I have do not fit, they are too large. It looks like a 1/4" would be too small.
I'm wondering if they might be some metric size?

I got those out of the parts book for BL200 loader, the only other spec it shows is "PT3/8" for both fittings....

There are at least two different styles of “ag” quick disconnects that do not interchange. I think discount hydraulic hose has a chart showing the sizes difference.

It turns out, the correct answer is,3/8" NPT ISO 7241-A Quick Disconnect.

Apparently this is the "standard" for loaders, and mini excavator type equipment.
