Hello, I got a problem with my 1998 Bigboss 6×6.

Chain coming from the trans to the middle axle broke and snaped on my transmition case. I repaired the case and put on a new chain.

Now the problem or not ? is that when the 4 rear wheel are above the ground only the rear one turn with the chain. The one in the middle move freely. They dont engage with the rear one.

I was wondering if they are supposed to follow the rear one when I turn it by hand or with the power of the engine. I also saw that the middle sprocket assembly seems loose. But again I dont know if its normal or not, I just want to make sure before I put everything back together.

Thank you very much , I need this ATV to plow my driveway !
