Lazy Hydro Pedal

[94BULLITT]

My pedal was sticking and it was the return spring, all of the 200 series have this problem. My tractor started doing it at 50 hours.

Dealer sent me a new Dampner/Return cylinder today to try out. It has more return force but also takes more foot pressure so I will, hopefully, get it on this weekend and try it. See if I would rather have more more foot pressure or slower return. My current one works OK if at 2000 RPM or more.

I had the same problem on my CK 30. Here's a link to my thread and what was done to fix it. The short version of the story is they replaced the HST, now it's fine. I just past 105 hrs and it's still holding, although I don't think the last one started until about 40 hrs and I've only put 35 hrs on since it was done.

Just got around to install my new dampner on the control pedal today. It makes a big difference. Now even at lower RPM pedal comes back nice an solid.

I was wondering how the new pedal damper was working on every ones tractor. My tractor is on the 3rd damper now and it started doing it after a couple hours of use on the last damper. So did the damper resolve your problem? I read that thing from the bobcat call trac (my dealer sent me the same thing in a email) and saw it says use your foot or brake but in a tight area that is not good if the pedal stays stuck.

I have not seen that from Bobcat, can you post what it actually says or provide a link?

I have never had my spring replaced and mine is still lazy, the dealer lubed it up once, but it never really helped

Look at post 23.

There is a new dampner available part #7022773. It has 2 springs in it, 1 inside the other. I put it on mine and makes a huge difference. This dampner is visually different, it does not have the fluid check hole at 9:00 o'clock position on side of the housing. It still has the drain plug at the bottom.

I'll look at mine and see if it is the new one, it is supposed to be but it could have got mixed up. Is the only difference you can see the check hole?

Did they charge you for it or was it under warranty?
If they charged you how much was it?

Here are pics of the new one installed and the old one. They removed the phillips screw check plug as a visual aid to indentify.

The price can vary by dealer because they may take different mark up. Suggested price is about $215. My dealer & I split the cost because we both wanted to see if it made much difference. It does make a difference provided you are running at 2/3 throttle (1900 RPM) or higher. The HST is designed to run at higher speed and requires the flow from the charge pump to serve 3 functions. 1 - supply cooled oil to replace what was dumped through case drain, 2 - provide pilot pressure oil for the tread pedal to stroke & destroke the pump, & 3 - supply enough oil to create a back pressure on the low pressure side of the HST motor to prevent free wheel/coasting.

I found that when running around 1500 rpm when backing up to connect an implement the pedal comes to neutral but tractor may not stop immediately because of the lower charge pump flow.

According to my dealer, they've had lots of experience with this issue. They tested the pressure you're talking about and found it was lower than it should be. That was consistent with what they had seen in the past with lazy hydro pedals and their fix was replacing the HST. Kioti requested several pressure readings that my dealer had to come back out to take and Kioti provided a replacement HST under warranty, so I'm inclined to believe it's not just an over zealous dealer. I hope another fix is found, because not everybody can or will have their HST replaced, but that was the bottom line for me.

My latest dampener has a allen plug on the top of it. It was made 10-24-11.

The new one will have the allen plug on top, will not have the phillips screw on the side.

That's is what I have.

How is it working for you? Notice any difference?

I have had 2 new ones and the current one acted up after a couple of hours. I think they are going to check something on the hydrostat.
