Are you running it much?
#1. Close the valve on your sediment bowl when not running.
#2) How's your compression? Badly worn rings will allow unburned gas to run by and into the crankcase.

When you figure it out I'd really like to know how it is happening, because gas running from the gas tank into the crankcase is physically impossible without you noticing something REAL BAD.
The carburetor on this tractor is BELOW the manifold, and is not connected to the engine in any other way. For gas to be running straight from the tank into the engine:
1. The carburetor drain would have to be plugged.
2. The manifold would have to be completely flilled with gasoline.
If the manifold is full of gasoline, the tractor will flood and not start. It may even hydrolock when it sucks in that huge slug of gas. Best case scenario is you take a gasoline bath when the tractor starts as it spits that huge slug of gas out the muffler!
This is something that wouldn't go unnoticed.

You must have bad compression as that is unburnt gad. Try new hotter plugs and maybe even new wires. How are the tappets are they set on 14thous hot. Like other post said no way for gas from tank to get in crankcase. Have you just bought the tractor or have you had it for a long time and what do you use it for.

As noted below, there are two ways it can get there. One is extreme flooding, the other is excess choke, or a cylinder not firing allowing raw fuel to bypass rings.
Do the following.
Always shut off the fuel at the tank valve when stopping the tractor for even a few minutes (just get into doing it)
If it runs rough, do a tuneup including a compression check.
Change the oil and monitor the level.
It could also be hydraulic oil. (I heard you say gas, but Hydraulic oil can cause overfilling in the crankcase from a bad seal in the pump. JimN
