Videos of New PT425 Arriving/Unloading

[Clumber]

Folks,

On the You Tube docclumber channel, I loaded 3 videos of the new PT425 being unloaded by the delivery person. I think there is an example of PT pucker in the second video.

Yep. That's the PT pucker! :laughing:

Best thing for you to do as a new operator is to go out and get used to it. Find something heavy and see how the center of gravity changes as you turn the machine. Don't lift things too high. Never travel with something lifted high. This is true of all front end loaders, not just the PT. Only lift a load as high as necessary and be very wary of lifting loads on cross slopes.

Did you notice the guy duck and look when he came trough your door? That is kind of funny. The PT425 canopy is not that tall. If I stand next to my machine, I can rest my nose on top of the canopy and I am only 6' tall. These are mighty little brutes and they feel larger than they really are.

Enjoy those toys, ah, err, I mean tools. It looked like Christmas!

Thanks for the advice. I have not ad much seat time sinced it arrived, due to work and wind chill below 15 degrees for several days. I have used it to rearrange the attachments in the garage with priority for winter use. I did get a little experience moving the huge snow blower in a tight space -- keep it low, keep it slow.

The articulated stearing and treadle design takes a little getting use to. I am used to the single foot -front/back usage. Does anyone know why the treadle is designed that way?

The treadle has been discussed extensively before; I am a fan of the two big toe method. One big toe on each pedal, always. It keeps you from accidentally lurching when you hit a bump.

All the best,

Peter

Don't know why they did it that way except that it is brutally simple and keeps the footwells small. I have a lot of experience on hydraulic drive machines from small tractors to really really large forklifts. I have had several direction pedal configurations and I like this one. The other one I liked had both direction pedals on the left foot and the brakes on the right. That was really good for positioning in tight quarters and on slopes. Since the PT425 has no brakes, I think this arrangement is best for it. You can use the opposite pedal as a quasi-brake on slopes. If it had a one foot treadle and no brakes with the opposite foot, you can get into situations on slopes where the unit will want to roll due to gravity. That transition of your foot from forward to neutral to reverse makes for jerky movement. Whereas the two foot method of the Pt425 setup on the single direction valve allows for much smoother transition in my opinion.

Not sure if that's the reason, but their mining equipment has the same treadle arrangement -- with the operator sitting sideways in the front 1/2 of the machine...

I agree on the "both feet" approach -- do NOT remove either foot from the treadle, and the opposite foot will help control sudden speed changes, whether those are operator-induced or caused by bumps or whatever. I've found that using both feet also makes it much easier to hold the machine in a fixed position on a slope.

I agree completely. Once you master the treadle, it is truly awesome. Best drive design I have ever used.

wow! ... great videos! ... thanks!

I remember the "taking delivery" event. ... Great moments!

Merry Christmas.

Thanks guys, I will try the both feet approach. I had experienced the sudden speed change thing.

So, the treadle is really a single direction flow valve. Pressing the right foot causes flow in foward direction, pressing harder increases the flow to the wheel motors which move the tractor forward faster. likewise for the left foot opposite direction... Using both feet to hold posistion on a slope or slow foward decent, pressing left foot more than the right seems to infer hydraulic flow in both directions, more so to the reverse direction providing a breaking action. Or is the left foot pedal also forcing the right pedal up causing reverse flow only to slow the effect of gravity on the tractor?

Also, Kent, I don;t understand the concept of the operator sitting sideways on the mining tractor. What is the advantage?

Thanks, Yes, nice event -- PT pucker and all. Santa came through this year. Hard to imagine better holidays.

Happy Holidays to all.
