I think you are asking if the transmission should have a "whining" noise?
Square cut gears are inherently louder than others, but if you have a very loud pronounced whine or growl coming from the tranny you may have a repair or maintenance needed in the future.
If you have not already done so, drain the transmission fluid completely, check for the presence of a white milky appearance, if none is found, I would refill with new gear lubricant. If you do find the fluid to be white, that is an indication of water and moisture inside which can ruin bearings, fill with kerosene, drive the tractor for 15 minutes, drain out and refill.
I would recommend doing this since it sounds like you just got the Cub and plus you may not know its history.
