Backhoe New Holland 758C backhoe noises

[Dave1953]

I recently purchased a NH TC34DA with 14LA loader and 758C backhoe. I notice when using the backhoe that some metal wrenching sounds seem to be coming from the undercarriage possibly where the hoe is mounted to the tractor. It occurs only when the bucket is in the ground and being moved. My neighbor who has a bunch of heavy equipt. says dont pay and att. to it. Could it be the dealer did not get all the bolts tight and something is moving when digging is going on? Also, I have not taken it off yet. How long does it take to take off with some experience? Thanks for all input.

The bolts are not tight enough where the backhoe and subframe come together and its moving slightly making the noise.
Tighten the bolts more.
