The Trouble with Tractors
If you have a small rural town, a ranch or a farm I suggest taking a look at the KraftWork Hayride PG offering out this weekend. There is an A version available also and apparently animations in the "hay" part of the build. The set is mod and while I haven't tried it, it seems like the tractor can be separated from the wagon. 30 land impact.
The best thing for ME (other than the price of course) is the really good LODs. Most (actually all I have found) tractors have very marginal LODS and so not all that great other than for photos. You can see both versions by going to the demo area.
