hydrostatic transmission experts? 3000 series

[william_wixon]

any hydraulic (hydrostatic transmission) wizards here on this group? wondering if it's insane to even THINK about messing around with the innards of the series 3000 hydrostatic transmission. wondering if it's possible to increase the forward speed by altering or making some kind of adjustments to the hydrostatic transmission.

There is an adjustment but if you increase the forward speed it will reduce the reverse speed.
There is a rob peter to pay paul effect involved.

thanks lbrown,
are you saying externally? that's been suggested a couple times in another thread i started recently. what i was wondering here in this new thread is if there are any internal adjustments that can be made. simple adjustments like maybe an adjustment screw or maybe even more complicated, involving disassembly and some simple machining of an internal part, you know, safely, without destroying the hydrostatic transmission or shortening the life of the unit by inadvertantly putting an un-designed-for stress on some part or the entire structure.

Bill, curious as to why you are running 2 separate threads on the same subject?

You will beplaying with fire if you begin to disassemble and machine internal parts to increase speed. Yoiu have to move more fluid to gain speed.

hi bob,
i thought long and hard before i started another separate thread on the same subject, well, not exactly precisely totally the same subject, pretty close though.. I was worried I may draw the ire of a tight group long time tractorbynet.com > cub cadet users if I started flooding the cub cadet board with the same question over and over again. Part of the reason I started another slightly different thread was I wondered if there might be a hydraulic specialist out there who may be scanning the subject lines of the posts and perhaps he may not have had any interest in clicking on 吐orward speed but if I used the word 塗ydrostatic maybe he壇 be interested enough in the thread to click on it. or even if there was someone who participates in discussions on the other manufacturers sub-groups might come across 塗ydrostatic in the subject lines and be curious enough to click on it. The other thread I got useful and helpful advice about adjusting the linkage and getting larger tires but I was specifically wondering if there痴 a hydraulics specialist who peruses these discussion groups may have extensive experience with this hydrostatic transmission and if he may have already *done* the modifications I知 wondering about. Either an external adjustment screw, or perhaps maybe even disassembly and machining an internal part. I thought perhaps 吐orward speed wasn稚 specific enough to perhaps draw knowledgeable individuals on the topic into the discussion. You can see by my information I致e been a member since ?6 and I hoped having only made 8 posts in that time I wasn稚 abusing my privileges here. I知 sorry to say I felt a tinge of resentment that you asked me why I started two threads. I wasn稚 hearing what I wanted to hear. Other people commented on some form of disappointment in the speed of their 3000 series and I thought it might be helpful to more than just me if I could (be persistent and) smoke out a hydraulics specialist. who already did the mod? So there.

Hey Bill,

Why doncha just put some big gnarly tires on the back a percentage greater in size to accomplish the proportionate increase in speed you're looking for?

I'm only half kidding!

Bill, one possibility is to find out what Kohler considers acceptable RPM range for the engine and set the governor for the top of that range. You would need some sort of tachometer to check the current RPM. I used to have one but it disappeared.

thanks for the tip bob.
i also adjusted the throttle lever throw (it bugged me that the throttle would start to engage the carburtor at the half-way point of the dashboard throttle lever throw). when i did that i saw there was a stop bolt on the throttle/carburetor linkage on the engine. i was glad i wasn't able to alter the top rpm by my fiddling around with the linkage. so far, as far as i can tell, it's set at the factory settings (for "full throttle"), which i assume is 3600. i don't want to mess with the max rpm.
i don't have a tach either.

b.w.

posting to both my threads. i'm completely desperate for assistance. hoping someone might be interested enough in one of my threads to click on it and offer their expertise.

(copy post from "forward travel speed")

the problem persists. am looking forward to making some progress. i've been considering increasing the engine rpm's from 3600 up to 3700 or maybe even 3800 to get the forward travel speed up to the rated 8 mph. wondering what the consensus on that action is.
