Any idea what size/brand hydraulic hose quick coupler fittings would be on a 175 that has the stock (OEM) female ends on it?  I'm putting a loader on it, and trying to save myself taking it apart, and running to town with the ends. Looks like 3/8 Pioneer 4010 would fit.  The manual I have doesn't specify. Thanks!

I'm sure it uses 1/2" not 3/8".

My 170 uses the standard ISO 1/2 in. fittings as does all my other tractors.

My 175D uses Pioneer 4010-4 for 1/2 inch pipe thread hose ends, they have the pointy tip and not the ball ends, we found that the ball ends will leak more oil from the hose when uncoupled!

I agree with big guy on the poppet style couplers. They also are easier to connect.
