Backhoe NH 758C Backhoe

In my part of town we have a large body of water (Nimisilla Reservoir) that for years had trees growing all over the dam.

Then one year the Army Engineers came in and said they all had to go. They dug each one out and filled the hole with a slurry of clay to re-stabilize the dam.

There were a lot of trees and it was a lot of work. )</font>

This tree was about a 10" diameter white oak that was growing on a natural slope that makes up the side of the pond, at about the same level as the leak. Id guess the distance from the tree to the water edge was about 25 feet. The previous owners were careful to keep the man-made dam mowed, but allowed trees to grow on the natural part, some of which is up to 20 feet below water level. It is thicker than the man-made dam, but has no engineered core. Last year after I found the leak I cut all the trees I thought were a threat, but haven't removed the stumps. I'm half afraid to remove them, but it probably won't do any more damage than the rotting of the roots.

I do, and I like the one you built. In your description you mention a top link on your 757C. I know the 757C is not exactly the same as the 758C, but since they do take the same subframe it seems logical they would mount the same way. Mine has no toplink connection, and I wonder if it should. When using it sometimes I can hear a knocking noise from the rear mount, as if the backhoe is moving on the back of the tractor. This was apparently the first installation of a NH backhoe the guys at my dealer had done, and I'm depending on them to have gotten it right.

I guess my question is, in addition to the two front pins that connect the subframe to the brackets on the tractor, what, if anything, holds a 758C on?

In the center of the BH platform is a small panel that is normally held in place by a spring pin. I remove the pin & cover and attach my top link to the mounting point under the cover. I then tighten the top-link to snug up the BH to the tractor.

The top link keeps the BH frame tight in the rear carrier located beneath the PTO stub.

If this is not real clear I can take a digital picture showing the top link attachment point.

Ah, a secret compartment. Those devious rascals. I'll look tomorrow to see if mine has one. I finally found the swing pin storage hole where everyone said it was - hidden right in front of my eyes. On mine there are no holes on the left side (left if you're sitting in the BH seat) and two different sizes on the right side.

My backhoe does not have a panel or a pin under the seat, but I did find the brackets that the top link can attach to. The only problem is the only pin I have long enough to span the brackets is too long to be physically inserted in the holes (due to other obstructions. I'll have to look for a pin just slightly longer than the "standard" 3-pt hitch top pin. I'm not sure if the top link was intended to be used with the subframe - there is nothing in my manual about it. But I don't see how it could hurt anything.
