Dip stick for hydraulic fluid level on Kubota L2650

[Ottb farm]

I’ve located the window to see level of hydraulic fluid, but isn’t there suppose to be a dipstick also to be accurate. It is a Kubota L2650

Not always, do you have your owners manual? Get a flashlight to help see the level. Some like to put an approved dye in the fluid...but not I.
Here for your manual. I looked and yours does not have a dipstick. Please take this opportunity to read your manual completely.

Some tractors have a sight glass while others use a dipstick. If the tractor is not level neither will be accurate. When parked level either works fine. Get your level halfway up the sight glass. You can see a difference of even a quart.
