Load match option- 4310

[Deere_4310]

Has anybody used the load match button on the console for extended periods of time? I had the load match engaged while I was using a 8' rear blade for leveling dirt for about 1/2 hour and then I notice that the hydro kept cutting in and out, like someone was hitting the brakes. I ended up turning it off, and everything starting working normally. I was under the impression that this option was used to keep the motor from dragging down during heavy loads, not just on the loader, but also from implements. Is it ok to turn this option on for an extended period of time, or is just used every time you go to pick up a heavy load, which would be a pain in the a$$?

4410, 388 hrs, load match never turned off. no problems used for fel , mowing, rear blade, and box scraper work.

I had a 2002 4310 with about 110 hours that was acting the same way. I always left loadmatch turned on. I know I was mowing when I noticed it. By chance I turned loadmatch off and it seemed to return to normal. I was going to call my dealer about it but I traded this past summer for a 4410. To date I have not seen the same issue with the 4410.

I was wondering if there were any computer updates for the e-hydro from 2002 to my current 2003 model. I thought I read at one time about some creeping issue that was corrected by a updated computer board but I'm not sure. I think there was also a user who had a hydro issue that required that the board be replaced.

It might not hurt to call your dealer and see if they would contact Deere tech with your issue and get there reply. My Dealer has been really good about that. They call me back and tell me they made the call and here is the answer they got. You might also want to have them ask about about possible computer board updates. Interesting concept. Updating the firmware for your compact.

35 hours with the Loadmatch on never turned off no problems.

The dealer told me not to run it for an extended period of time with Load match on, but I was under the impression that you could run it constantly. I would imagine that if JD did not want you to have it on all the time, there would be all kinds of warnings in the manual, which there is not. The 4310 that I have is an early 2002, you guys may be right about the 02 models. If anybody else shows no problems with theirs, could you please state what year model you own.
Thanks

'03 - no problems, I leave it on! You are right on about warnings in the manual, Deere would never be too shy to place a warning if one was warranted!

I say this over and over. Dealers support such a broad range of equipment, they may err (hopefully on the side of safety, and still be great friends.

Your right about safety at JD dealers. When a mower comes in with a broken chute we fix it and when I mow grass for the dealer I have to keep the safety guard in place to set a good example for customers. PTO shafts and MMMs are dangerous as well as other parts of the tractor so stay safe guys. /forums/images/graemlins/grin.gif

2003 4410 no problems. When I turn it off I tend to find the tractor bogging down and losing rpms. I prefer having it on at all times.

Your jerking with Load Match on could be an engine speed sensor problem or a throttle sensor out of calibration. Both are pretty easy fixes by a dealer technician. However, before you call the dealer, you might want to check if the throttle rod has slipped at the engine.

Remove the right side panel and find where the rod coming from the throttle connects to the swivel at the engine. With the throttle handle all the way back, start moving it slowly forward. If the handle moves much at all without moving the throttle rod, then it has slipped. To fix, loosen the hex screw at the swivel (4 mm, I think), pull the throttle handle all the way back, then apply slight tension to the rod while retightening. Tighten it good. It is easy and at least worth a quick check.

 

[Deere_4310]

Roger it's funny that you mention "calibration". I had it in the dealer last week, and they did an update for the 02' that called for some type of "calibration". I am assuming that it had something to do with the speed. I never really put a load on the tractor before I took it in, so I am not sure if this caused my problem or not. I talked to the dealer and he said bring it in, they will put a guy on it to either troubleshoot it or do the research neccessary to find out if this is a known problem and what steps need to be taken to resolve this issue. They are very busy with harvest season going on. The only problem I have is that it only seems to happen after an extended period of time when the tractor is hot and under a load, not sure they are going to be able to duplicate. I will keep you guys posted with any updated information I receive.
Thanks

Yesterday I had a project to level a large pile of dirt with my 4410. Not sure if it was me but something just didn't seem right with the FEL performance. I had the 48 BH off and had my boxblade on. I pushed into the pile of dirt and a few times it seemed like it didn't want to lift it. I backed out of the pile a bit and it would then lift it. I didn't feel I had a bucket a dirt beyond what it could lift. It was loose dirt and I was at edge of the pile. I raised the engine speed to PTO mowing speed. Seemed to help a little. I then tried turning off loadmatch and it did much better at lifting but you could see the engine lug a bit. I got the job done and didn't think much of it until my drive into work today.

Last week I was doing some work pulling some stumps with the BH and moving large piles of dirt with the FEL. I didn't recall and issues like yesterday. I even used the FEL to lift and move two very large pine stumps. I have the power beyond kit for the backhoe.

With the BH off there is a loop hose for the power beyond kit. It has a very tight bend in the hose. I was wondering if a restriction in this hose would cause a drop in hydraulic performance? With the BH on this hose is not connected. Not even sure if I have an issue as it was my seat of the pants feeling on FEL performance yesterday.

On the loadmatch. It was explained to me by my Dealer the way JD explained it to sales when it was released. They drove the compact into a pile of dirt with and without the loadmatch on. I asked if loadmatch came into play using the FEL or BH. My Dealer thought not unless I was moving. I'm not sure if that is correct. It seems to me loadmatch is watching engine speed and might limit hydraulics to keep from lugging the engine. I was not moving yesterday while trying to lift a bucket at the dirt pile. I tried it with and without loadmatch and got different results.

I spoke with my Dealer and they asked if I might have had the 3pt up very high with the boxblade and in relief. They feel this could cause low FEL performance. I do have the 3pt adjusted so it lifts the BH high enough to get the pins in. I could have had the boxblade lifted up to the max setting. Will have to check this out next time I'm using the FEL with the boxblade.

In a normal cruise at 1800 RPM, with hydro in "B" range, the speed slows (no stop--just slow) when load match is engaged. Is this normal? FEL works better, and engine doesn't lag with bucket full, etc. with it on -- only speed is reduced. /forums/images/graemlins/confused.gif thanks,

LoadMatch on my 4610 eHydro seems to work as advertised. In fact, it was the second feature I "tested" (after the cruise control!!) to see if it worked. I pushed the FEL into a pile of gravel at 2000 rpm, Range B, with LoadMatch off and the engine lugged down as the tractor came to a stop in the pile. I did it again with LoadMatch on and I went about the same distance into the pile but the tractor slowed to a stop on its own with only a slight decrease in engine rpm. It was as if I was lifting my foot off the hydro pedal to match the engine power available, but I had my foot in the same place all the time. Pretty neat. The one discovery I have made is that LoadMatch, at least on my tractor, in Range B, tends to become proportionally less effective as rpm is reduced starting at about 1800 rpm and below. At around 1200 rpm it doesn't seem to make a difference if it's on or off. In Range A, it works down to about 1000. My tractor was delivered in July. I know the computer controls this function, so maybe I have benefit of the latest software load that might address some problems ya'll may have. Oh yeh, it seems to work the same using the box blade, too.

Thanks for the info...I guess mine's working okay then too. I have a 4710, just turned 50 hrs., and I think I was running too low on the RPM scale. As I said, it works great when operating the loader, and, like you, I can see a difference when loading. The only thing (negative?) I've noticed is that the speed reduces -- no change in RPM -- when running @1700-1800 and the load match activated. When I deactivate the load match, the speed returns to normal.

In short, I think I'm okay /forums/images/graemlins/grin.gif unless of course, someone else had the same condition and had it corrected.

Again, thanks for your input...

Well, I picked up the tractor today and this is what they found. They had to download a new program into the computer and they changed out a speed sensor. I have not had a chance to load down the machine to see if this fixed the problem or not. They tested the unit for 2 hours and stated that everything should be fine. All I have to say is thank God that it has been under warranty all this time, otherwise I don't know what I would have done. I am thinking about looking into buying an extended warranty, if there is such a thing. All this electronics is very new to the service guys, they are just starting to train on this stuff, making them very "GREEN". Hopefully the techs will have better test equipment and a better understanding as more people start bringing in the newer machines.
