</font><font color="blueclass=small">( In defense of the
BX1500, the ENTIRE BX series has more power than their lightweight chassis and small tires can put to the ground. But if all you are doing is mowing, light to moderate FEL work, and using non-PTO powered or low PTO power implements, you don't really NEED the extra HP. It's easy to get "Tim Taylor Syndrome"... MORE POWER! ARH ARH ARHHHHH!!! )</font>
On flat ground, I might be willing to agree with you (assuming we agree on what "light" FEL work is).
On hills, I don't think that's true. With my BX 2230, there have been several times when I have been pulling a heavy load in my utility cart (full of dirt and rocks) up my hill (don't know the grade, but not so steep its dangerous), and I have had to crank the throttle all the way up to keep going. Also, I have been using my FEL to dig into a hillside to create a more level walking path. There have been more than a few times that I've needed all the juice I could get to push the FEL to the limit--get it to push, curl and lift just a little bit more. So, to tell you the truth, I've already managed to reach the limit of my 2230 and I don't have any PTO implements in the back (although I will be attaching a 60" MMM in a few weeks).
Lastly, I don't think anyone is pushing him to get something bigger than the 1830. We are just warning him not to get less than what he needs, so he doesn't regret it later (like I have myself). Also, I don't think anyone has suggested he go get a 30 HP CUT. He wants a SubCUT, and the only question is whether 18 HP is enough, or if he'd be better off with a bit more (22/23). You are probably right that 18 HP is plenty, but if it doesn't cost much more for a fairly significant jump in power capacity, it might just be worth it.
