...My tractor is 24hp, 4x4 and weighs roughly 3,000lbs. Are light duty attachments a good match for my tractor.??
I drive a YM-21010D, similar in terms of weight and power. I have a small stable of Yellow TSC implements - KK; and I believe that these are well suited to tractors like mine. I have not had any issues whatsoever, and I use this equipment extensively. With about 250+ hrs on my Box Blade, SSoiler, Finish mower, RCutter, and Carryall, the equipment has performed admirably. I believe that this line is advertised as appropriate to use for up to 30 HP. I don't know about that, but it has handled my use very well.
As has been noted, there is little in the way of standards in this line of work, and some folks appear to be comfortable labeling all of company X or Y's equipment as 'good' or 'not good', without reference to the product line, or intended use. I have investigated other manufacturers sold in the area; there is a dealer who carries Great Plains and Woods, definitely premium manufacturers with a great rep, but honestly if you are comparing apples to apples on a product to product basis, there's little justification for me to pay 1.5-2x the price for essentially the same thing. While there were apparent differences in the finish of 3pt equipment, I was not impressed with the differences in material, weight and design to justify the cost difference.
I think in general terms, 3000 lb and 24 HP would be considered 'light duty' by most implement manufacturers, or at least it's at the bottom of their matrix for the equipment they design. For the most part, with 4-5' implements, there's only a few options for Medium or 'HD' implements on most product lines. If you were gong to use specific items in adverse conditions, or commercially, going to a Med or HD version may be warranted. And of course, these definitions are highly subjective. While I use my equipment responsibly, I also push it to do what needs to get done. I live in an area with rocky, hilly, difficult ground. Frankly terrain that many would consider difficult or crazy to even use a tractor in. Still, the "regular", 'standard', or 'light'
duty KK stuff has held up well.
On the other hand there is some equipment also labelled 'light duty', that is clearly designed and priced for intermittent use with lower-powered equipment. These tend to be knock-off brands or product specifically designed for use with BXs etc, and that light duty class might work well with a BX, don't know, but I suspect it would be compromised quickly with something bigger and heavier, regardless of HP rating.
