I have found these new tools to be just fantastic.
I had a great experience using the seeder. Contrary to earlier posts, my extra fuel remained in the can when I logged back on today. I didn't have to refuel as I had a sufficient amount left to do what needed to be done.
I bought a harvester for aesthetic reasons. I do not plan on using the harvester as I prefer to allow neighbors, buddies or market workers earn XP points and coins. Also, I value the additional income from my crops.
But, seeding is another issue. Since no one may seed for me, I find the Seeder to be an invaluable tool.
Thanks to the developers for bringing this online.
I have reviewed earlier posts and find some complain that they can't use their equipment on other farms. Even if it were possible, your daily allotment of fuel would not permit you to do much. At the rate of one gallon per field, half your allotment is used on your own farm. An active farmer wouldn't have enough fuel left to work many farms. Perhaps, only one! Remember, you can only refuel one time per day.
So I suggest that we should be grateful for these improvements to the Farmtown experience and enjoy them. Use whichever tool helps you the best and enjoy the rest. They all look great on anyone's farm.
