1) Larger tractors work faster when they are not broken perhaps. You seem to damage your equipment regularly and certainly more often than any other TBN member I've come across in almost ten years. Think about it.
In total, I've damaged three gas caps, one cab top, the front grill, two rear fender extensions, and the gas tank. I'm a believer of running what I've got, and fixing and modifying as needed. As a result, I fabbed up guards to protect stuff the first time the tractor made it back to a tinkerage. Remember, I'm the first to put an NX into the woods in North America and talk about it. The first to put on three sets of remotes when the factory said we couldn't. The first to put on a third function and make it with hard lines. The first to sound dampen the cab. The first to fab up and install belly armor, a thing that every tractor in this class should come with but doesn't. And then you must consider what kind of material I'm processing and how fast.
2) Waste not, want not. Pissing away money on gadgets and more HP than needed to do the job is simply wasting resources. If you have extra cash, send it to Oxfam or Save the Children.
Why did you get a tractor? Surely you could do some of those tasks with a spoon. Wasting your money, right down the drain.
3) You seem to think nobody could clear land before someone reprogrammed your engine to put out an extra 15 hp. All the land clearing functions your tractor provides are also present in a 45hp version of the identical tractor which is more than adequate. You could run a six ft bush hog with 33hp at PTO just fine. You might even manage to use it without breaking it. Your extra hp doesn't improve your loader functioning one iota. Using extra HP to ram things will break it however.
You're projecting. This is entirely your argument. Others have attempted to point out your factual errors, but facts fell upon def ears.
4) Don't trust my experience, ask others about their experience. Have you read any posts from others doing land clearing who felt a DK40/45 was not enough tractor to get the job done?
Never a worry that I'll trust your experience. After all, like your argument implies, given enough time, a person could clear a forest with a diner knife and a coping saw.
5) I acknowledged that some remote functions might benefit from a diverter or third fxn valve but I also pointed out that the vast majority of users here are only operating a simple grapple cylinder. No need for fancy valves to do that simple task. If you like playing Nintendo games with your joystick that's fine but don't oversell the need for something other than a basic control valve for a simple task.
Yes, nicer, more efficient setups work better and are easier to use. If a person can afford to get these nicer set-ups, then why not? After all, nicer set-ups makes tractor use and ownership all the more enjoyable and productive.
