I also purchased a 4310...back in December. I have loaded R4's (Rimguard), iMatch, eHydro, 300CX loader, boxblade, and MX-5 cutter. Initally I used it to clear out some snow using the bucket...still have not purchased a blade or blower.
Over the past few days, I have been able to exercise it for what I really bought it for...grading the driveway and cutting my fields. I have to say I am very impressed with this machine. I don't feel like there is a lack of power whatsoever...in fact I find that I really need to be careful as it has plenty of power to get me in trouble fast if I'm not careful!
The cutter went through the fields like a hot knife through butter and the boxblade did a great job of collecting material and dragging it back up the driveway. At first, before really using it, I was wondering if the eHydro was the best choice. I can say without hesistation that this I'm very pleased this is what I purchased. With a rear implement, I am constantly looking rearward while feathering the implement up and down (my land nor driveway is not flat). One hand is on the wheel, one hand is on the 3 point lever, and the foot is on the hydro pedal...works great. The Loadmatch feature is real nice, particularly when using the rotary cutter and getting into thicker grass. The machine compensates nicely.
Overall - I'm pretty pleased. At this time, my 4310 is limited by the operator rather than its capabilities.
Next - a landscape rake!
