I just purchased my first Kubota a L2800 it needs a bit of tinkering but its pretty awesome. First problem is its missing the tachometer cable don't know why but it wasn't there when I bought it. How do I find one for it ? second issue is a 2 part problem 1st the hydraulics have a slow settle well its pretty quick is there a good starting point to check? and 2nd the hydraulic fluid is a milky brown I have changed it once but it remains milky is there a good way to combat that ?
