I need to add substantial weight (500+ lbs) to the rear of an International 2424 in order to have enough traction to use the front end loader to dig out a pond and move all the dirt. The tractor wheels do not have holes for mounting weights. The tractor already has a 500 lb box scraper and liquid in the tires and that is still not enough weight to give the traction to keep the rear wheels from spinning with a loader full of dirt.
Any idea on how much weight I can add to the box scraper in the form of suitcase style weights?
Can I add weights to the rear axle maybe by bolting them to the empty mounting holes on the rear axle as shown by the yellow arrows in the attached image?
