I purchased a 2010 BR7070 twine auto wrap recently. The previous owner said that they baled 3500 bales with it. I have baled my first 35 bales now I have some questions

1. Left side bale size sensor is not visible on the auto wrap monitor. I checked the sensor and it is clean and not blocked by hay. Right side works great. So far my bales look great, except for the first 5 bales I did. Any ideas to test the electrical side of the sensor?

2. When I drive straight everything works great, but any slight turn the vibration from the pto shake my tractor enough that I’m worried my pto will break. Could this be a pto shaft that is not true or straight? Should I replace the shaft?

3. Rear door lock does not move to the locked position. I try to move it up put it won’t go high enough to move over to locked. Any ideas here?

4. How to you fix an issue when the idiot (me) baling accidentally opens the rear before the bale is completed and before the twine has been engaged? I found out closing it and continuing to bale is not a good idea.

Thank you for your responses. I do enjoy reading all of comments on other posts. Moving from a NH 316 to a BR7070 is a big jump for me. Any help would be appreciated. -Todd

2. Make sure your drawbar is set in the right position.

4. Dump it. Unroll it. Bale it again.

Welcome to HT.


1. Lock tail gate, up have someone move sensor while watching monitor. 


2. Check universals (I operated mine this year, with draw bar in the 1000 RPM position with no problem, baler is 540 RPM, BTW).  At least that's my experience, you have like 5' of shaft between universals.


3. Does door appear tweaked?


4. Same as HiTech, except you might cuss the operator out, the next time.  ;)

On the door lock.  Spray some lubricant on the shiny part of the spool visible under the valve block.  Do not try and pull up on the lever, you will just bend it.  At the first bend after the handle leaves the valve block, take the heel of your hand and bump the handle up.  Once the spool moves up, lubricate the spool on top.  Move the handle up and down so the Orings in the valve are lubricated.  If the spool now moves easily when moving the handle at the first bend, but not at the end of the handle, the handle is bent and twisted.  Remove the handle and remove the twists and straighten the bends if the handle interferes with the side shield.

My experience with the BR baler door safety locks was that they tended to get sticky if they went disused for a long time.  As mike10 said, you can lubricate the spool externally, or do what became a routine procedure for me; if I encountered a stiff safety valve I would work the spool back and forth gently for a little bit, 10 or 12 cycles would usually do the trick, until the spool moved freely from one extreme to the other.
