The block broken out like that is really bad. The tractor side frames that support the front axle attach to those holes as well as the loader. The only way I know of to repair that to last would be to replace the block and also most likely the frame rail is damaged as well. A good machine shop may be able to salvage the block but most likely engine will need to be totally torn down. The extra loader frame braces would take some of the stress off of the frame but I think you need some solid threads in the block to have any strength at all. With bolt holes broken out like they are I don't see how that is possible.
