The newer front mount version L4479 is listed as an option for the L3560. It is 74".
I just picked one up from my dealer with a couple dozen hours on it... so got it for almost 1/2 price. Was looking for a plow blade and rear blower, but my dealer offered a great deal on a front mount blower (which is what I have always had for the last 25 years). I have not had a chance to use it yet this year because of a light winter so far this year. I did ask the Kubota rep also, and he said with the HST the worse case is you slow down if it bogs down in wet stuff. Would be more of a problem with a GST. I would think if you are dealing with cold light snow, then you would be OK but your power is on the small end of the requirement. If you could afford more power it would likely be helpful to make it go faster.
The upside with the front mount is it is so much easier in the neck and back than turning around. The main down sides is the frame and blower combo is huge and takes a lot a lot of space to store; and it is a bit of a pain to mount and dismount... my last blower (BX2750D) would take 5 minutes... This one takes 30 minutes, and it is a different alignment issue each time (I need to find a loose bolt somewhere I think).
Also, the L4479 is really heavy (and heavy duty) which I am concerned it will dig in to much while the ground is still unfrozen.
Good luck on your choice... unfortunately, I do not yet have enough personal experience with mine to help you much.
