[QUOTE=J-Mech;271923]While all this is mostly true, the distance between the upper and lower links is the same on the super. Just taller tires. And why would he have to remove the lower hitch (drawbar)? It can stay on with the sleeve hitch.
It's all true, yes you need to remove the hitch plate (behind the hitch) to get to the rear axle housing to install lower sleeve hitch mount and should lower the mount also for equipment to run level. The upper sleeve hitch rod will hit the hitch plate if not removed.
Most equipment is designed to be operated level when attached to the draw bar (typically designed height for 23" tall tires). When installed on 26" tires (and remember they run a narrow rim on Supers so they are even taller in the center) it moves the draw bar up higher from the ground being bolted to the rear axle housing. You can relocate the draw bar height lower ( modify plate and re-drill holes) to a more level point for attachments although on anything with a fixed length lift link would throw off the lowering capabilities so it would need to be lengthened the same as the draw bar was dropped.
For instance a rear tiller on a non super is designed to go approximately 6" in the ground. Raise the draw bar height 3" to 4" and it changes the depth (yes you can adjust the lifting chain to make up for some of it). You can simulate this by placing a 4X4 under the rear tires and seeing how much it throws the attachment off when raising the draw bar height. Single bottom plows can be adjusted for the draw bar height and depth in the ground by adjusting the crank.
You also find this on front mount snow blowers such as the 450 model where they have adaptor plates and longer lift links dropping it to make up the difference in height of the Super so the blower runs level and is not pitched forward.
Operating equipment such as snow blades on trucks (and garden tractors), this pivot point is very critical as to how the blade operates and is why there are so many adjustment holes in brackets for its height adjustments on trucks (I installed Western Snow Plows for several years). Too low and the blade rides up over the snow and too high it trips easily.
