Need a Hydraulic Adapter

RedLeaf · May 19, 2020

I have owned a JD4700 for quite some time and have a number of attachments requiring hydraulics. I recently bought a Kubota MX5800 and would like to buy some hydraulic adapters so that various attachments an be used off the back of both tractors.

Because of COVID-19 lockdowns here in Ontario, my Kubota dealership only takes phone orders for parts and has curb-side pickup. I have been unable to get them to work out what adapters I need. The Kubota has four Pioneer ports off the back, and on the 4700, I have the "Power Beyond" system.

I am hoping that someone can identify the male fittings used by my attachments (e.g., log splitter, dump wagon), so I took a couple of pictures for someone more knowledgeable to tell me what the male fitting is and suggest a specific adapter. Hopefully, I can order these adapters from my dealer, Princess Auto, or Amazon.

Thank you.

Your tidiest, cheapest option is to replace one set to standardize what you have. IMO of course.

Your pics look like ISO 7241B

ISO 5675 "AG couplers" are the most common on CUTs. They can be ball or poppet valve, they mostly interchange. 1/2" can flow up to 12 gpm, so that's the most common size used for remotes on CUTS.

My concern is cross contamination of hydraulic fluids.

I wouldn't be worried about contaminating the fluid between JD and Kubota. the last 5 gallon pail of Kubota fluid I bought said it met the j20d spec so they must be similar. other tractor brands maybe especially older stuff

Probably a toss up. An adapter would be made with a QC coupler of each type with a pipe coupling in between. A forged steel coupling may cost more than a QC. The adapters will need to be on only one machine. Just for simplicity; I agree with you Big Barn. Just save the removed one in case you sell the odd one out.
