Brush cutter questions

[jbc28]

I just bought a new 60" brush monster for my T190. What's a safe hydraulic temp while operating? I'm seeing about 90 - 100 deg above ambient. Also what rates are most people getting for cutting/land clearing? Thanks.

In school, I was taught to design for 180°F max operating temperature. In practice, it is not unusual to hit 200°F - 210°F. Much over this for prolonged periods, and you could run into oil breakdown issues.
I am assuming that the 90-100° over ambient that you are hitting is in °F, correct? If so, and you do not live in the desert (why would you need a brush cutter?? LOL), you should be okay.

On a hot (90°) day my T250 std flow hydraulic oil temp is around 153° when clearing/moving trees with a hydraulic powered tree saw and about the same when just using a root rake w/double grapples when cleaning up and stacking logs.
