Load Match question

   / Load Match question #11  
Dan, I just looked through my manual, 08 Model 3320 and there is no mention of a function w/o the LM switch to turn it off. I went and tried my tractor using the selector switch and I could not find a way to turn it off.

So, I guess you have to have the LM switch to perform this function.
My manual (September 08 build) tells how to do it with the display switch. I don't have the book here, but you can turn it on and off that way. Your dealer can give you the steps if it is not in your book.

I am in the minority with the load match. I leave it off most of the time. The load match is always changing my ground speed faster or slower when I don't want or need it. Seems like any light load on the motor (ie small hill), will make it change speed. Too bad they did away with the switch - easy on or off.

Why do I want to lug the engine? Because max torque and hp is not at rpm speed. Most diesels will have max torque and hp near the 1800-1900 rpm. This is probably the max work efficiency. I will work my tractor at the typical higher rpms but as the work load occassionally increases I have the reserve power to get through the tough spots. With load match on all the time, it never seems to allow the engine rpm to decrease much and IMO changes to speed to much.

This is exactly how I want to run the tractor. I am use to gear drive tractors and you know how much power you have left. My dealer did tell me today that the book I got with my tractor was last years because mine got damaged. On page 35 the instructions are clear on how to shut the load match on and off. It is not as easy as pushing one switch but it can be done.

Using LoadMatch (eHydro)
LoadMatch enables the operator to prevent the engine stalling during heavy load applications such as operating with a loader. This feature is turned on and off using the display mode switch
1. Turn key switch to ON position.
2. No error codes should be displayed. If any errors are displayed, activate the display mode switch (A) to acknowledge the error.
3. Press and hold the display mode switch (A) until the display reads 途ELEAS?
4. The last edited command will display, either Coast or Load.
5. If Load is not displayed, use left or right turn signals to select the Load command.
6. Activate the display mode switch (A) to edit the LoadMatch setting.
7. The LCD (B) will display the last setting for LoadMatch, either On or Off.
8. Activate the left or right turn signals (C) to turn LoadMatch On or Off.
9. When the desired setting is displayed, activate the display mode switch (A) to store the setting.
10. The LCD (B) will flash the entered command twice and then change to the normal mode.

I think I will spring for the Automotive cruse kit because I will never remember all of this. Why couldn't they have left well enough alone.

Thanks to all that posted
Dan

OK, fair enough. Maybe I'll find the same when I really put mine to work getting my yard going this upcoming spring.

You'll enjoy the cruise. It's great for mowing, tilling, etc. The speed +/- function is great.

I think the load match is so prominent now because with a hydrastat most people when they get in trouble like bogging down under a load tend to give it more pedal/lever (instinctively) like it was an accelerator pedal on a gear machine. Of course that only bogs it down even more to the point of sometimes stalling. Ideally you let off the tranny lever to let the engine catch up or increase the rpms (load match)
I've had hydrastats for many years and know better but with so many first time buyers now, I'm sure they were getting alot of feedback, " I want to return this machine, it stalls or feels under powered under load doing everyday tasks"

The 08 tractors do not have the switch. I talked to the dealer again this morning and he THINKS I need to buy the auto cruse kit be able to switch the load match off.

This makes little sense to me. Loadmatch is not that useful of a function that it should be enabled by default, should be the other way around imho.

It came in handy for me today, I posted earlier that I don't really notice a big difference with it off or on but that's because I probably never worked it hard when I tested it off, since I just leave it on all the time.
Today I was working it hard in the snow in mid range which was fine for the majority of the work but on some runs plowing, the load got real heavy where it could have used low range. that would be pain switching back and forth between ranges, rpms were already high so I couldn't gain there.
Without load match it would have been seriously bogging down or I would have had to be extra careful feathering the pedal preventing it from stalling, which I'm capable of, having owned HST's for over 25 years, but with the load match it's easier just keeping your foot into the pedal, you don't notice it as it's really seamless.

For inexperienced users, they would be stalling and unhappy. I guess like many other things it's a dummy feature!!!
like anti lock brakes, personally I like to be able to lock up my brakes and feel less in control not being able to, but statistically it's proven to prevent accidents.
I agree it should still be an easier option to select, though I can't think of a task that I would want it off myself.
It does make it a little spongy in high range, definitely no spinning the tires or tractor drifting:(

I guess the usefulness varies with local snow conditions and how much road travel one does on their clearing runs. Up here conditions almost always require full rpm at all times so Loadmatch would not be useful, at least not for clearing snow. But I guess I could use it while loading snow into trucks with the bucket, as this does not require full throttle. But unfortunately I have Error 8 so can't use Loadmatch even if I wanted to. Too many storms up here for me to fix the error yet.

I really like Load Match for almost all situations. Example- I am preparing my new house site with my '06 3320 and 6 ft box blade. I am ripping some heavy clay with sections of decomposed sandstone and then carrying it off to push over the edge of the hill. With the scarifiers down in low range and 2500 RPMs I push the go pedal all the way down and Load Match maintains the RPMs at around 2000 by varying the gear ratio to accommodate hard and easy sections. I can do this myself without Load Match, but I would rather let the tractor handle it because I can keep my attention on the angle of the box blade and where I am going. Except for when I am just having fun driving, there are very few situations where I turn off Load Match because I have to really pay attention to do better than the computer does, even when just driving up the road.
