It depends on the tractor.
Hi Mine uses 134a Dave
There is no parking brake. You hold the tractor in place by putting it in park like a car with auto trans.
Diesel will hold 12 quarts and Gas will hold 8 quarts
8qts
7 qts
As much as the fuel tank can hold
Crank tractor set tractor throttle at 1500 rpm turn steering wheel all the way to the right hold it for about 10 seconds then turn it to the left and hold it for about 10 seconds repeat several times and the air should be gone
there are 2 bolts at the front that hold down the front plate with hood latch remove those bolts and the whole front plate with latch comes off.
Depends...by "diesel tractor" do you mean "farm tractor" or "semi tractor"? You're SUPPOSED only to put off road diesel in a farm tractor. That's why they make it. If you have put it in a semi tractor, get hold of your dispatch/brief/lawyer right away for advice on what to do. If you have a pre-2007 engine your trouble is almost exclusively legal. If your engine is 2007 or 2010 compliant, you're probably going to screw up your EGR and diesel particulate filter, which will break your engine.
It varies from tractor to tractor based on size of the hydraulic pump and lift needs. Please give more info for a specific ammount before trying anything on your tractor.
