Yeah, I was wondering this. And now you're going to find out why I will never have a career in marketing.
I'm totally out of step with this one. I mean, I'm sure you're correct, but I think they're wrongheaded in their strategy.
The highest HP tractor will hit all 3 HP requirements. Too much power is never, itself, a problem.
Less HP is generally something you accept because you need a smaller or lighter machine -- which is fine, because a small light machine can't use huge power anyhow.
So what they are doing here, for all but the highest HP model, is building more machine than the customer needs, and dialing it back, and probably getting a bit less money for it.
For that matter, it's less cost effective to have dealers stocking more models when one would have satisfied all the needs.
It's like the computers they were selling maybe 20 or 25 years ago in which parts of the microprocessor were disabled. They didn't cost makers any less to make, but the makers sold them for less.
I don't get it.
But then, if you put me in charge of selling raisins, I'd make rabbit-shaped dispensers, and have you lift the tail to have a delicious raisin dropped in your palm.
Guess I need to stick to my day job.
