John Deere 457 roundbaler help

Hoping someone can give me some ideas to help with this baler.The baler has megawide pickup,best monitor and variable core ability.Twine only.

 

I recently purchased the baler from a relative who does a little buying-- selling of equipment.He purchased the baler directly from a farmer who supposedly had the dealer go thru the baler every year after harvest.It has had some bales thru it but does look super slick.

 

Anyway,the first field i baled was eastern gamagrass and everything went well.The next field was a sudan-sorghum field and i had nothing but problems.The baler did not want to start a bale with the pickup clogging up.Once it did start it made a nice bale.However,after six bales i had to shut it down as hay had wrapped around the top idler roller.This roller is the largest roller on top right above the bale forming chamber.It was primarily under the 2nd,3rd and 4th belts from the right side of the baler.This roller has the rough part of the belts against it.

 

I ended up baling the field with my old jd 510 baler and had no problem.If you have ever used a 510 they are a finnicky baler so anything it could bale the 457 should have had no problem with.I do have the compression rods off of the 510 over the intake.The 457 has its compression rods adjusted as high as possible.I thought maybe the next time i try it i could remove most or all of the compression rods ?

 

I was told by someone to check the cam bearings on the pickup which i will try to do when possible.I have never run as modern a baler as the 457 even.Newest i have ever run is a jd 435. 

 

IF anybody has any ideas i would appreciate it.I just don't understand what could cause hay to wrap up around the top idler roller besides the problem with the pickup.
