No idea on the Howse brand (well do have idea but not facts) but ask around if you live in farming area. You may find a true farm single row one for very low price. In some parts of the world they were popular but have gone the way of other single row implements. Just be sure you can still get the wear parts for it or modify to fit. Then others will tell you to buy lower price new and save gas money for look...ok...but the old farm subsoiler will be better built. Check and see if your State Dept of Agriculture does not have a sales site for used farm equipment. Many do and can be great source person to person on such. I don't think you will find the low price ones out there today have any shear bolt protection to it. If you go that way really would not put full size pin in the top link. Do check the max working depth on any brand you look to buy built today.
