Sounds like either low hydraulic fluid, fluid with too high of a viscosity, an air leak in the suction hose, or clogged up hydraulic suction filters. My bet would be on the last two. Are you seeing any fluid dripping when the tractor is not running? How many suction filters does that closed center system have?

Welcome to TBN
1st thing to check after checking to be sure hyd oil level is at the full mark is the frt hyd pump drive coupler. A worn drive coupler can create some odd noises. How long since hyd oil suction screen has been checked/cleaned?

Actually there are 2 filters(trans & frt hyd pump) Rarely is filter(item 45) in frt hyd pump clogged.
This tractor doesn't have the two piece coupler and four rubber bushings.It has a solid one piece shaft. Hydraulic fluid is full, only had this tractor a month don't know when it's had anything done.

Sounds like you have this pump drive. I would check for loose fasteners at the very lease.
