No Guts HI gear HST

[getut]

No Bob (not definitive, but based on answers I got from my dealer).

My dealer mentioned that the Kioti HST unit pop off pressures are set by the use of a tempered spring. Not an adjustable setting.

If anyone knows this to be false, please speak up.

Ok, then looking at the problem from a different point of view, what about using a stronger spring substituted for the stock spring? Again, you couldn't go crazy and seal the thing up with tension/pressure, there still needs to be the ablity to have relief in some circumstances, but an increase of even 10% might be a big help???

</font><font color="blue" class="small">( I have not even seen a gear drive in our area (northern VA). Want to check one out. Cant find pics of gear drive in brochure or website. Want to see the pedal/gear lever layout. Is it still an 'open' floor plan. I do like the operator room on the CK20H. Ease of mount/dismount is important to me. Will do lots of pulling/dragging with whatever tractor I get.)</font>

Here are a couple of photos of the CK20 GEAR platform/operator area. Hope this helps you. Gerard

thanks Gerard, looks like the only change is the small foot throttle.
only saw one photo. I did not understand a previous post about the two stage clutch/no live pto issue. No live pto means pto stops (does this mean mid and rear) when push clutch in? two stage means you have intermediate position with the pedal? when does this effect your operation?
thanks

whoops, second photo arrived while i was typing last response.

The CK20 is 20hp, yes? I have an late 80's Kubota B8200HSt. it is 19hp, and the same size as the B2710/2910. In fact, it is the great grandad of thiers.

I have seen the Kioti's, and believe the CK20 is about the same size/weight as mine(about 2250lb with loader and scraper installed)

Anyways, in Hi range, mine is GUTLESS. 19hp is just not enough to move it except over flat land.

I do have slight advantage; I have a three range unit. I have plenty of power in low range. Mid range is where I do most stuff. Hi-range is for going downhill with a strong tailwind

Calibrated springs are a bit of a black art best left to OEM situations. Not only is pressure an issue, but pressure at length, and all that would be spec'd on the HST unit. Finding a spring that works properly from a company would be nearly impossible without having specs on the spring that is currently in there.

Believe me.. I had already thought about that one.

Whenly... the live PTO/2 stage clutch issue...
A live PTO is not positively tied to the transmission. A normal PTO is. The downside is that if you push in the clutch on a tractor without live PTO that is running something such as a rotary cutter, the tractor will want to keep moving forward. The rotary cutter acts like a flywheel and keeps putting power into the transmission driving the wheels. 2 stage clutch (on a tractor with live PTO) disables the PTO only in the first stage and then both wheels AND PTO in the second stage (depressed further).
Also the gear model PTO speed is directly related to travel speed. So if you go slow to mow around something... you ***MAY*** not be turning the PTO fast enough to actually cut the grass.

Actually, it's 21 HP. Gerard

Sorry to keep responding to EVERY post from everyone.. but

RobertN... I bet your will pull a boxscrape full of material in low without stalling the HST. It will either pull it or spin the tires.

Again... this problem is most easily reproduced in high range because it takes less resistance to reproduce the problem. The problem still exists in low range. It is fully an HST problem... the mechanical transmission that comes after the fact to switch between high and low doesn't matter.
