I have refrained from posting "hearsay"- especially negative stuff about a brand that I don't own. But in light of this post, I will pass along what I was told by a trusted friend who owns several NH tractors.
Again, take this for what it is... a second-hand story.
The guy who cuts & bales our land owns an '04 TC40D. He came a few days ago to pick up the bales. Last year he used the NH but this year he brought his old MF ag tractor. Knowing how much he loves his TC40, I asked why he didn't bring it to load the hay.
He said that he was at the NH dealer picking up some baler parts and they told him to NOT use the TC40 to load bales. According to him, they had 6 TCs in their shop that had split in half after the loader bracket (sub-frame?) broke and all the stress was transferred to the engine/tranny coupling.
The supposed fix is to strengthen the current bracket and add a second attachment point to the frame. He said he would not be using the loader to move bales until he could get this enhancement done--- after hay season.
Obviously not what happened here, but still might be worth noting.
