Just curious, what dealer did you get your tractor from? Is it the factory loader? The factory system requires you to choose wether you want to use the loader, or the three point lift or the backhoe, they use the quick connects, and that rediculous tank on the rollbar for the FEL and a tank on the backhoe. It can be plumbed in series using the lift box tank as the only resevoir. Do not try to connect the extra tanks in series, I have sold a couple of hydraulic pumps to folks who had problems with this setup.
The KAMA is a good tractor but their loader arrangement leaves a bit to be desired, we use Koyker loaders.
