If that winch has the self contained hydraulic pump then all you need to do is unbolt, remove and blank plate the PTO outlet on the tractor. If it has a separate engine driven pump you will need to remove and blank plate the pump mounting as well.
Thanks. I'm pretty sure it is self contained.
Looks like the dozer blade needs to be pitched forward so the back of the blade is straight up and down, it will dig allot better and not gouge in the ground. Extend the tilt braces out. Once you have it tilted forward then check the tilt cylinder so it tilts the same amount each way.
