Where do i bleed brakes JD 1140 4wd?

[Deere_Norway_2000]

I bought a John Deere 1140 4wd where I have to pump the brakes to brake properly. The level at hydraulic oil level indicator was below minimum so i'm gonna fill it up and hopefully bleed the air out of the brakes. I've only done this on cars and hope it won't be hard on the JD. Only issue is that i can't find the bleed nipple like cars have. From the brake cylinder two pipes go to each side at the rear axle. Do i have to loosen these pipes and pump the brake when bleeding? I feel like this isn't the best way to do it...
On beforehand from Norway, I'll appreciate all answers

Brake systems on those tractors are a bit different from cars. On the 1140 the bleeder screws are usually on the wheel cylinders themselves, not right at the master cylinder like you might be used to. They're smaller and can be easy to miss if you're looking for something the size of a car bleeder. Since your post got cut off I'm curious about those lines going to each side. Are you looking at the brake lines running back toward the rear wheels or are these going somewhere else. A photo of what you're seeing would help me point you in the right direction.
