The problem or i should say the challenge is to size the tractor to the intended uses. The flaw is that one "FINDS" new uses.
There's a whole lot of truth in that statement..
The only way to decide how much tractor you need is to lay out exactly what you want to do with it regularly. I could use a backhoe a couple times a year, and a dozer maybe once every two years. So, there's no point in me buying either a backhoe or something with enough power to act as a dozer. I'd like to have both, mind you.. I'll hire someone to do those jobs, they can pay for the extra machinery, not me.
A lot of the replies to this thread have been right on the money. The first one I'll comment on is safety. If the tractor is overwhelmed by the trailer it's hauling or the bush hog hanging off the back, it's not safe.
Never mind what they say, size counts.. if it's too big or too heavy to fit into the area you're working in, it's pick and shovel time.
I have to drive around my house to load attachments because my septic tank/line/field is in the way on the short route. Bigger tractors with AG tires are tough on lawns, I've left some nasty tracks when the ground was soft.
Will it fit into your garage? Does the ROPS fold? How much ground clearance do you need?
Can you hold enough fuel for a day's work, or are you stopping to fuel every couple hours? Mind you, I'm usually ready for a break myself after a couple hours, so it's not always a problem.
I have 10 acres, about 7 in pasture. I spent the past two afternoons mowing pasture with a 5 foot bush hog, another afternoon will see it done. A smaller tractor will mean more time, and possibly less comfort over rough ground.
We haul out firewood in the winter and remove snow from a 250 foot driveway.
Long and short of it is, almost everything we do could be done with a smaller tractor, except maybe shift small round bales. It would take longer and the machine would work harder. As it is, I was reflecting on my choice this afternoon, and I'm glad I got the size I did. It's a good match for my abilities and the chores it does.
Being able to haul it around behind a truck is a real plus if you have more than one location to use it. Nothing I have will haul the 3400, so it's limited that way.
