I have a Speeco Cat 1 QH. It is well made. It's width is on the narrow end of the CAT1 spec. I also have a Landpride RBT3584 rear blade, which might be on the wide end of the spec. When used together they are a force fit, and then usually a bit of pounding is required to get the Landpride to drop when disconnecting. Therefore I recommend measuring your implements and the QH carefully before buying. My tractor has telescoping 3 pt arms, and because of that and one other thing, I've found that the QH saves me some effort, but does not really save much (if any) time. The "other thing" is that I have a backhoe, and if I want to switch from the hoe to something like a rear-blade, in addition to reattaching the 3pt hitch, I also have to attach the QH, so that's one more thing to do and sort wipes out the time-savings. Gets better when only switching between 3 pt attachments. Some rainy day I will do some grinding on the Landpride and try to get a bit of clearance. Or at least a bit of angled lead-in.
