I have the Prowler Tracks predator model that I use on a Cat 242 (look very similar to the ones you showed). I did have to add to the boom stops for clearance on the front. Main use was to be able to feed round hay bales in the winter, and they work great for that. The added 500# is nice with a brush cutter too. I haven't noticed any loss of performance, and they are great in loose material. But you sure will tear up turf with them on- no more running up in the yard for a quick task. Pretty rough on your pavement or concrete also.
And as was mentioned, no fun loading on steel ramps on my trailer either.
I'd like to find a trick to mounting them. Even with the tensioner tool, a real pain to mount.
