I enjoy farming, but I do not really think that spending more money to buy similar machinery would increase my enjoyment factor significantly. 

All the mud/track talk a while back resulted in me having a telecon with another member of this forum not far away on Halloween day.....he pointed out that he had done all the modifying, changing, mounting, dismounting, breaking, fixing stuff I am doing now in the past....and then he advised that I should look into golf clubs or airplanes.   At the end of the day, after a particularly fun day in the mud with several bits of collateral damage, I called him back and asked him to tell me more about the airplanes!
