What type/spec hydraulic oil to use.

Tx Jim · Oct 13, 2019

You need hyd oil that meets or exceeds JDM J20C spec's. JD hyd oil is called Hy-Gard.

Use hygard or Mobil 424 or chevron thf. Leave the store brands on the shelf. Especially if it?s a power shift or quad range . I have used harvest king premium j20c spec oil with ok results I found in my 3020 that it caused leaks . When I switched back to hygard the leaks stopped

Does anyone have any experience with Kendall Hyken 052 Lube.
