I had the same problem. An injector was bad, replaced, and it went away.

The black tar substance is nothing more than unburnt diesel fuel. You need to work the tractor a little harder. Get it warmed up good every so often and that black goo should go away. If you need to, take it out on the road and run the engine wide open for a couple of miles.

2 miles @ top speed represents just about 8 minutes - barely enough time to burn the deposits out of the exhaust but not enough to prevent the bores glazing, with loss of compression, more blow-by and worsening symptoms. The engine needs some genuine hard work on a regular basis. Also check it is running at thermostat temperature, not below. If you continue to run in this manner, you can expect a big overhaul bill for compared with the amount of work the tractor has done.
