Re: PT-425 PROS & cons??

I think he's out mowing every lawn in the state with his Hustler; partialy becaus he thinks it's that much fun to mow with and partially to prove me wrong that the next size up with pumps/wheel motors [somewhat like a PT!! /forums/images/graemlins/cool.gif ] is a more durable configuration. /forums/images/graemlins/grin.gif

Ok, made my guess; where have you been hiding Fourteen?

</font><font color="blue" class="small">( Hey, where you been lately? )</font>



<font color="red"> Same old place! Just busy with other things (cardiac surgery, new car, new ATV, selling old car, etc)!

It seems that most of the improvements, changes, and upgrades have been completed on my PT-425. No Kohler engine problems, of course. At over 275 hours, everything, including the reversed wheels, reversed Stump Grinder, and Grapple Bucket, has been completely trouble free!

I'll try to provide some input, but, after reviewing the last few months of postings, I don't see much new - mostly questions which have been already answered, some extensively, before!!

<font color="red"> Stop considering! Just do it! REVERSE YOUR WHEELS!! You'll never want to go back!!! </font>

How do you feel about undue stress being put on motors or shafts?

<font color="red"> Visualize that the footprint at the wide wheel setting overlaps the footprint of the narrow wheel setting by 67%, since the inner 7" of the wide setting sits on the same ground as the outer 7" of the narrow setting.
When sitting on a flat hard surface, there would be little, if any, added stress because the wide stiff tire would resist any slight leverage effect, and the position of the hub/wheel interface has not been changed.
Now visualize the tire riding lengthwise along a 1" diameter pipe. In this unique situation the wheel can rotate radially.
If the pipe was positioned under the shared 65% of the footprints, the hub would experience the same radial torque at either setting.
If the pipe was positioned somewhere under the outer 3.5" of the wide setting, there would be a slight increase in radial torque, but I doubt that it would be a significant amount, or that it would exceed the design limits of the motor.
This is a scenario that would seldom be duplicated in the real world, except, perhaps, riding over a small stone or root near the outer edge of the tire where the entire load was supported at that point, a condition which seldom occurs, and if it does, it does so for a very short duration.

There are many factors which can increase the wear on, or reduce the service life of, a Power Trac, or any vehicle. Liquid filled tires, for example, greatly increase stress on wheel motor shafts due to the large reduction in tire compliance.
I believe that the benefits of reversing wheels for SOME owners, in SOME situations, may far exceed any slight, if any, detrimental effects!! However, this is a decision, like many others regarding the use and care of a PT-425, which must ultimately be addressed by the OWNER for HIS machine being used by HIM in HIS situation!!

Or being more exposure for sticks to puncture hydraulic hose’s and such?

<font color="red"> No such exposure! See #519768 - 10/27/04 at PT-425 PROS & cons?? </font>


<font color="red"> PS: I have used my PT-425 with reversed wheels for over 275 hours with NO ill effects! These were nearly all 'high stress' hours - many spent lifting and carrying heavy loads over rugged forest floor for long distances with complete confidence, not mowing grass!!

If I ever do develop a wheel motor problem, I will consider it a tiny price to pay for the superior stability and safely of having a 'Wide Track' Power Trac!!


PPS: Tire pressures should be 11# front and 7# rear! </font>
