Flat lander? Two wheel makes sense.
Hills, I got a story to tell:
Boss and I were talking about how after 250 hours in the seat I was getting pretty good with the tractor. He says, "Don't go getting over-confident. 250 hours you are still a newb."
I was working around the barn and on level hard pavement so I had dropped Missy Ferg out of 4 wheel into 2 wheel.
Well, wasn't 3 hours later he proved that I was a newb + and idiot. We are in the mountains. 4 wheel drive is required to manage the steep hills. We needed to carry a walk behind brush cutter to an area we cannot cut with the brush hog on the back of the tractor. We loaded the cutter on the forks and had nothing on the back. We don't run loaded tires. All the old tractor guys here are going - "Uh huh. I know where this is going!"
Now I know a tractor only has rear brakes. I know when you put a load on the forks, you need ballast
. I know when you are going down hill with a load on the forks, you must be in 4 wheel or you will need to change your shorts if you survive.
Yep, shorts were changed and since I am writing you, I did survive. But it was a hell of a fun tobbagan ride with a high center of gravity machine.
Don't get over-confident. On hills use 4 wheel. Before going down.. check that the tractor will hold on a slight incline! Use ballast. Don't be an idiot like me.
