I just bought a td25da at an auction. I feel stupid to have to ask this, but I can't find a dipstick for the hyd oil level. I'm getting a manual but was wanting to use it this weekend. Thanks
You might try to look for a "sight glass" on the side of the transmission. It is a clear lens, usually about the size of a quarter. There may be two lines on it for "high/low" levels.
It is usually near the floorboard on the driver's side (left side).
Look right behind the top of the PTO shield to the right of the center of the tractor. It is a little black knob that pulls out. It will have a single line which is the full mark.
