The dl120 and its replacement are both u.s. made. Like the dl95 the dl120 replacement is fully u.s. manufactured.
You said " dl120 loader on my 1643 is American made...and is seemingly better than the new loader that replaced it."
Could you be specific how it is better than its replacement. The more soecific the better. Welds, gussets, weight handling, hydro line protection and positioning, bucket pins and connections to tractor etc. Etc..
I understand the new loaders are American made, too. I was simply pointing out that the new loaders aren't somehow an upgrade because they are made here, because the previous loaders were, too.
As far as the specifics, if you look at the mounts, they don't look as rugged or robust. In fact, I was struck by how much lighter they looked. Strike #1.
Strike #2 was the loader arms themselves. They just don't look as strong. The arms on my DL120 appear to be more rugged than the arms on the DL125.
Strike #3 was the bucket. This was the most obvious difference between the two loaders. The new buckets on the 1700 series tractors are smaller, with less depth (volume), and are constructed out of thinner steel than the previous buckets.
This is my second Massey compact tractor (my first was a 1540 with loader), so I can see the progression of loaders/buckets over the last ten years or so.
The one part of the new loaders that look as good or better than the previous model is the hydraulics. I don't know if they ARE better, but they look more stout. Having said that, more hydraulic power on chintzier loaders isn't exactly a good thing.
Personally, I'm glad I bought this 1643 when I did. I just wish I was able to buy a 1660 before they were discontinued, too.
