Great!! The cords have worked perfectly for me for 125 hours. I'll bet their kit is more expensive!!

I informed PT of my concern about the floppy treadle on the all hydraulic PT-425 on 2/25/4.

" 9) The Treadle Pedals are too floppy and are difficult to control safely particularly on rough surfaces! (I have installed strong Neutral Position Return Springs with zero preload.) "

Last week I unlooped the cords as an experiment. The experiment lasted about 4 minutes! They were quickly reinstalled! Still using the original cords, which show little wear, and no failures!!

Do their springs install at the center, or at the ends?? Compression or extension?? Zero preload??

I highly recommend this modification, their way or mine, particularly to new owners!

Wonder if the latest batch of PTs come with these pre-installed.... /forums/images/graemlins/confused.gif

I think I may have gotten the first PT out the door with the springs. While testing their demo model, I commented that the treadles sure were touchy, and Scott told me about the springs. They put them on at no charge (which is reasonable considering they are probably a 50 cent item and take 30 seconds to install.) They told me that I probably would end up taking them back off as I got used to it, but I think they make it much more easy to operate. I got the strong impression that they feel real men don't use springs, but hey whatever makes life easier is my motto.

The springs are mounted above the treadle assembly just inboard of the removable black panels that make up the sides of the 'transmission tunnel', about six and a half inches from the outer edges of the foot pedal portions of the treadles. So when you press down on one side of the treadle, you are compressing the opposite spring. When the treadle is in the neutral position, there is no load on either spring.

They seem to work very well, although I doubt they provide as much resistance as Fourteen's solution. I have used the 425 for as much as 3 and a half hours without experiencing any fatigue to my calves and ankles. Hope this helps.

Thanks for the report!!

Like many things in life medium is best. If there is too little resistance, the weight of your foot must be held up off the pedal or constantly balanced with pressure on the other pedal! If there is too much resistance, your foot gets tired from constantly pressing down hard on the pedal! My Wal-Mart cords are a little too strong. When operating for a long time at constant speed and direction, my foot gets a little tired from pressing down. For bucket work, MiniHoe, Stump Grinder, Forks, and Brush Cutter, particularly on rough ground, they are just right!

I could search for slightly lighter cords, or make the attachment points closer to the tunnel, but since I don't mow grass or travel long distances, I'll leave well enough alone for now!!


Real men think about what works best for them, not about what 'Real Men' may think of them for not thinking like them!!!!
