[AT] Gear case oil: If a little is good, a lot is better?

[Greg Hass]

Could be water in the oil but as a side item, which may or may not apply, 
many of the older Farmalls had in the owners manual that if you were using 
the tractor for a lot of stationary work you were to add a certain amount 
of extra oil to the transmission. I don't remember the exact amounts but I 
do remember reading about this for the 350 that we once had. I think this 
was to better oil the gears as at least half of them weren't turning on 
stationary work. A 2400 IH loader tractor we owned had the extra high 
capacity hydraulic pump on the side of the transmission. When that was 
installed the book said to take a hack saw and make a new line on the trans 
dipstick one and one half inches above the old full mark and fill with oil 
up to the new mark. The newer tractors such as my IH 574 don't need extra 
oil as the return oil from the power steering sprays through a tube over 
the top of the gears. My 2 cents worth.
