Here is an interesting video on a CK3510SE with a 12' bush hog mower.

Good discussion. I went with the ck3510se. I was quoted over $1800 more for the 4010. IMO if you need more hp you should step up at least one frame size and think about 50hp. It really only makes a difference for ground engaging work, larger implements.

I put the extra money towards a 3rd function and top & tilt, cause the SE has rear remotes already installed.

I have not found the ROPS to be in the way. Just trim stuff up higher or smash through it. A canopy probably wouldn't last long on my machine, at least until I get things cleaned up a little more.

When I bought my ck4010, my options were the CK4010 or the larger NX4510. I chose the CK4010, but I suspect that the larger NX4510 with its turbocharged engine would have been a better choic, not because of the five additional horsepower, but because the turbo should raise the entire torque curve, giving the tractor more low end grunt. Power is what sells tractors, but torque is what moves loads.

The larger chassis would better transfer the power to the ground, as you state.

I am not crazy about that video. I think it is a little deceptive. He uses it for grass and very light brush, almost like a finish mower. I think if he had some brush greater than 1" (that piece of equipment is rated to cut up to 2" brush) he would have some issues. Rhino Ag sells a 10' flex wing brush cutter that is rated for brush up to 2" that has a minimum PTO requirement of 25 hp. I would go that route well before an unmatched piece.

The turbo doesn't have anything to do with the torque curve. It will raise or lower the torque in proportion to the horsepower of the engine. The stroke as compared to the bore is what changes the tq curve. If two engines share the same displacement the one with the greater stroke and narrower bore will have a higher tq and lower hp and the one with the wider bore and shorter stroke will have a higher hp but less tq. If you look, you will see that the CK and NX share the same engine block, the NX has a turbo but the bore and stroke is the same. The turbo and it's boost rating just let more air into the combustion chamber providing more hp and tq.

Wrong. A turbo can be matched to an engine many ways. Most commonly, a wastegate or VGT turbo is used to boost low end performance and avoid overboosting at the top end.

Back in my farm tractor engine development days the turbo versions of a given engine family always had higher torque rise than the ma versions, and I doubt that has changed in the past thirty years.

Bore and stroke relationship has little to do with torque curve shaping in a modern turbocharged hpcr fuel system Diesel engine

I looked it up, you are right. I stand corrected. I have been wrong before, you can call my ex, she will vouch for that.
