I will chime in here because I own this exact box blade. I got my L2501 tractor in may 2019 along with some quick hitch and root rake and bucket and such. I wanted a box blade, and elected to go with the cheaper TSC option over a more expensive name brand option. I have 13 acres. I use the box blade sparingly on all sorts of little jobs on the property, and I didnt want to invest a ton of money on something that will be used here and there. Ive used this box blade now for over a year and a half, and it is one of the exceptions to the county line tractor attachments. I typically wouldnt buy county line attachments for something like a mower or rototiller. They come with cheap chinese gear boxes, also things like the disc harrow when I was in the market for one of those, the county line ones are light duty, made with angle iron. Their box blade though is farily solid. Its just a lot of welded steel, so as long as the welds are good it should be ok. I looked it over good. Ive drug mine all through the woods, snagged it on roots and all sorts. Backed it into trees a few times clearing land. It has held up perfectly. Ive not had a single negative issue with it. No welds have broken or cracked. It still mostly looks like it did when I left the store with it, and I keep it right outside in the rain and weather. It is quick hitch compatible as well, so works with my QH15 just fine.
Compared to the Land Pride options, you really don't see the gap on the box blades like you do other pieces of equipment. For example the County line option here is 395lbs. Two land pride options at the same 5 foot width are the BB1260 and the BB1560, those are 346lbs, and 428lbs, respectively. Also the county line has 5 shanks on the 5 foot box blade while the land pride only has 4 shanks. When you compare the two side by side, look at the welds, the gauge of steel, the scraping blade, etc....The county line is very comparable. I would argue the Countyline may be even better than the BB1260. The BB1260 goes for about $750 or so I believe. The BB1560 is a bigger 5 foot box blade (more capacity, so the box is larger), but it goes for over $1,000 and is only 33lbs heavier. These things are nothing but steel welded together so weight is a good spec sheet judge of what you're getting. I dunno, when I done this comparison back in 2019 I chose the county line option to save money, and I feel I made the right choice. If I was going to use a box blade heavily though, I might would go with something diferent, but for the odd job here and there, and just as a general counter weight for loader work, it works great.
