And you said they have a stouter loader?
Yes, but it seems loader specs are sometimes suspect, so take them with a grain of salt. The LS loader for the 4041 and 4047 is spec'd at 2,634lbs to full height, at the pins according to the loader manual (the website still shows 2,500lbs from a previous version. The NH 250TL is listed at 1,940lbs to full height, at the pins. The NH does have 10" more lift height, so that should account for some of the difference. The inference in breakout force was somewhat larger in favor of the LS. 700lbs may not matter as much as the 10" to some folks....just depends.
I'd like to have an extra 10-12" of lift height, but it's really not limiting what I can do. I have run out of lift capacity many times, so I wouldn't want less than what I've got.
Aside from that, the operator's station isn't as big as some people like (fine for me) and I'd like more room between the fender and brake pedals....maybe a bigger fuel tank (it can still run about two days on a tank) would be nice. I haven't found a perfect tractor yet, but I think the things I'd change on my LS are really insignificant in the big scheme.
With all that said, take a look at a Kioti DK if you can....very nice machines, and just slightly more expensive....and their loader is a bit more powerful than the LS. I haven't got any experience with the Massey 1600 series, but the reports here all sound positive so far.
