My NH TC33D (with filled 15-19.5 R4 rear tires) is similar size and weight to your Kubota
L3301. I needed more traction to get up and down a hill in my gravel driveway which was proving impossible when things got icy or in hard-packed snow. I started out with 4-link, Ladder Style chains with v-bar studs. My thought was that they were less expensive and lighter than the 2 link v-bar ladder chains. I'd give them a try, and if the ride proved too rough, I could add cross links, converting them to 2-link ladder chains. They were very easy to put on, once I learned the trick - just a couple minutes per chain. They provided the traction I needed to drive up and down the hill while pushing snow with my loader or boxblade (I don't own a snowplow or rear blade that angles). Surprisingly, the 4 link chains were smooth enough to drive on hard surfaces at high speeds. Their shortcoming was lateral traction: driving on side hills in my woods was a problem. The v-bars help a fair amount over the bare tires, and I suspect over ladder chains without studs, but it was just not enough to be comfortable in the woods.
My next try was DuoGrip chains with v-bars. These provided both good forward and lateral traction, and worked well in my woods. They also had plenty of traction for getting up and down my icy driveway when removing snow. My issue with them was driving at even medium speeds on hard surfaces. I thought I was going to shake myself or my tractor to death. Just going down my +/- 1/4 mile driveway at anything more than snow removal speed was out of the question. Since I need to drive my tractor 5 miles between two properties over the road from time to time, these were out of the question. They were on my tractor less than one winter season. Had it just been driving through my woods (where the combination of moderate speeds and softer ground were just fine) or the relatively lower speed of snow removals, they would have been perfect for my needs. I still have them, in like new condition, but have not used them since that first winter. (they are for sale, if anyone in my area is interested)
I finally went with what I should have gotten all along, but originally thought were overkill or too expensive for my needs: the "European style" studded chains. I got the Ofa Eko 8 chains for about $500. Great forward and lateral traction, while still giving a very smooth ride on hard surfaces. There are other brands with similar styles which are also good. In my opinion, you can't beat this style chain for excellent traction and smooth ride. The studs may be an issue on pavement, but that's not a concern for me. Even if I do eventually pave the loop in my driveway near the house, I'll still use these chains, and just try to be careful to minimize spinning the tires.
