2021 LS MT2 25S
My hydraulic couplers for the backhoe/rear remote seem to be a wonky size. I've tried to fit them to 3/8" and that's too big. 1/4" is too small. Does anyone know what size these are? Tractor supply and CAL Ranch didn't have anything but SAE sizes.

Also, beware of the rear remote that has the L shaped tube. Mine snapped off and now I'm going to have to work to make something else fit.

They might not be "standard" AG couplers. See if the 7241-A 3/8" couplers might fit.

Unfortunately they don't. Took a male coupler to the stores. TSC carries 3/8 Pioneer and CAL Ranch carries Apache in 7241-A. Neither 3/8 fit as the inlet in the female side is too large.

OK. So ISO 5675 and ISO 7241-A.....the only size that is common (will fit) to both ISO's is 1/2".
A male 3/8" 5675 will not fit into a 7241-A, it will be slightly too big.
A male 1/4" 5675 will be too small.
Maybe you have a 1/2" coupler. Possible. Take a dial caliper and measure exactly what you have. If 3/8" male in 5675 and 7241 are both to small for the female coupler...then try the 1/2".

Why not just change them to the common Pioneer couplers instead of trying to 'sork' them.
I will likely have to do that. I don't know if you guys are aware, but TSC is phasing out and has on clearance 1/4" and 3/8" couplers. An associate told me they'll no lomger carry anything but 1/2".

Anyone else notice the local TSC has one small aisle of tractor parts?

I'm confused. It didn't fit and now it does?
Thanks for the help. That was the right size and I'm back in business.
Interesting.

The Apache was probably in the wrong package. It likely wasn't a 7241-A. It didn't work. I ordered a coupling set from Amazon and that 7241-A fit perfectly.

Glad you got it figured out.

Great!
Sorry Jeff B got your bizness however :p
I would love to give it to someone local but it's surprisingly harder and harder to find tractor parts. Even dealers here aren't carrying a large selection of parts.
