lemme answer the question you didn't ask. I looked at both of these lightweight cutters. I even demo'd an LX6.
You can do it. But front weight still will help. You don't have to use a loader. Loading the front tires, using wheel weights, suitcase weights or fabricateing front weights of your own would help a lot.
Filling the front tires can be almost free, and may not significantly add to compaction.
Free weights (weight lifting barbell weights) can be used if you can find or make a bracket.
To me these light cutters are too light. They are too easily damaged. I would probably look at a heavier 5' cutter first. YMMV!
As you probably are already aware, I pull an MX6 with my 4310, but of course, the loader stays on!
