Stanley the Belarus 5150 appears to be a sturdy, classic-looking large-frame 4x4 50 HP ag tractor.
Jim, in order to have a FEL-mounted blower you will need a "harness". It's a PTO extension that runs underneath the frame from the rear PTO to the front of the tractor. You will find those at your blower dealership. In your case it may have to be custom-fitted.
