I have a Meteor snowblower and it is a reasonably good unit, but there are many out there that most would consider to be of higher quality. It is generally lighter weight than many of it's competitors. I have a short, paved drive, so I couldn't justify the additional cost of a higher quality unit. I preferred to have hydraulic rotation and a hydraulic chute deflector on a Meteor to a heavier unit that was all manual for more money. Just my personal choice. I would say your tractor would handle the 51 in all but the worst conditions. In those cases, you would take a smaller bite and you should be fine.
