The hydraulics on my 4020 have started making a rattling noise like the pump is starving for oil but the hydraulics still seem to work fine . Any ideas
 
Mine chatters a little when you first start it but otherwise works good. In the shop right not because the front pump is leaking pretty badly. Maybe a rebuild or replaced pump will fix the chatter problem.
 
When mine started rattling I replaced the pump coupler bushings. They fell apart in my hand when I went to change them they were so worn out.
 
Only about 4 years old replaced with John Deere bushings it seems like it?s coming from under the floor board
