None. They worked fine earlier and are working now. Maybe TBN had a glitch when you were on.
BTW, my cache is emptied each time I close my browser, so I'm not looking at cached images.
More torque for my Power trac?

I noticed they are loading slowly, displaying line-by-line. They take much longer to load than most, but do come in eventually.

I was on at the same time, Moss. I am still not having any issues. Must be a network thing somewhere.

Yeah, I just loaded one that I didn't have in my cache and it took 12 seconds.

I just looked at the size of the file and it was just a tad over 1 meg in size, so that may explain it.

Stray,
Have you had one wheel off the ground to see what happens to each of the wheel motors. It would seem like, if one wheel is off the ground, all the pump fluid would go through that motor, and with little resistance, and very little pressure. Have you noticed /heard the relief valves activating in the parallel mode. Have you done some of the impossible things that you could not do before. I still don't understand how you can put 3000 psi on 4 wheel motors rated for 1500 psi. Perhaps you have not exceeded the 1500 psi yet. I am thinking that when you said you noticed some improvement, you may have been running those motors at their peak psi rating, whereby they normally would run at 1500.
I ment to ask you about the different type tires on your machine. Is the overall diameter of the lug tires and the lawn tires the same?

JJ the tires are close the same but not the same. I believe when we talk theory and forget about the reality of say wheel efficiency, wheel motor leak through, flow dynamics and even tire-ground contact creep we tend think things that should happened do not and things that should not happened do. For instance one wheel off the ground and no torque to the other three. While in theory the other wheels would have no power but in reality while it does decrease power to the other three there is enough resistance in the motor and lines at free spin (especially at full throttle) to leave some power to the other three. . And if a little pressure is put to the free spinning wheel (some contact to the ground) then much more power is put to the other three. I don稚 know what the traverse pumps psi is set on but I would be willing to bet it is closer to 2000psi than to 3000. Also when feeding 4 individual wheels there is a lot of volume to fill to reach the pumps maximum psi output. Even with that said I have at several times in full throttle pushed up against a pile of dirt, pushed as hard as the pt could with all wheels on the ground and none spinning. The pt would just grunt and bog down if I pushed it past its power limit. The PT does seem to push much harder in the 4 parallel mode than the factor mode.
Thanks JJ and others as well for keeping this discussion alive. It is bringing out a lot of points and facts about the aspects of this project that I could never cover by myself. I will keep posting my findings and experiences right down to the last blown wheel motor. If it happens that is. But I truly do not think it will. Knock on wood. LOL

Stray, if you push hard while picking up something heavy that should take some load off the rear wheels. I would think that you would get wheel spin and not be able to push as hard. Or even lift the rear wheels off the ground. Try that and give us a report.
