                  Power to weight ratio, output shaft thrust load capacity and power density are all generally higher within the HSM line vs. the Dodge TXT line.  The writer expresses that their is a clear advantage to using the HSM over competitive products like it.  The HSM has roller bearings fitted throughout its entire inner workings were as the Dodge TXT has roller bearings only on the output shaft.  By having roller bearings throughout, the HSM has axial load capacity on the output shaft ideal for screw conveyor applications.  The Dodge TXT has ball bearings everywhere else within its internal structure maker is weaker.  From a mounting perspective, the author highlights that the HSM reducer already has a machined flange were as the Dodge TXT does not.  The HSM allows the end user the ability to mount a turnbuckle torque arm easily and correctly onto the gearbox without having to loosen the casing bolts.  This eliminates disruption of the case half sealing.  The article goes into detail in regards to the accurate realism the that Dodge product line does not offer this feature.
                The Dodge TXT requires the end user to select a right or left side mounting configuration during the ordering process were as the HSM does not.  The HSM input shaft can easily be adjusted from the left side to right side or vice versa.  This is explained, in detail, very well by the writer.  There are a multitude of accessories available with the HSM including: backstops, taconite seals, vertical mounting modifications, motor mounts and finally specially designed hydraulic inputs.  One leaves from reading the article that he writer has taken the proper time to do their research on the specifics of the product.  Some of the HSM offerings mentioned by the author are also available within the Dodge TXT product line.  Probably the biggest advantage pointed out in the summary that the HSM has over the Dodge TXT is it's taper grip bushing. The Dodge TXT product line comes with a taper bushing that has a fixed bore size.  This requires both ends of the shaft to be accessible.  For all the described reasons, the HSM is a superior purchasing decision vs. the Dodge TXT.
