4720 Load Match

[sunnyside360]

Call me a dummy. First I went to my manual. then I went to the barn. For sure the switch is there (its a 2005 by the way). I guess I never noticed any benefit/reaction to its use-and lump "load match", Motion Match etc into the same pot. And I have almost 900 hours on the machine-mostly mowing, snow plowing, loader work.

The Load Match switch was removed on the newer 4x20 tractors. My 2010 4320 does not have the rocker switch but my older 2007 4320 does. You can still toggle the Load Match function ON/OFF on the newer machines via the programming controls (ref the Operators Manual) and the factory default setting is ON.
Only time I notice much difference is when traveling up a steep grade in High range -- speed will decrease while engine rpm's change very little.

My 2011 4520 still has the rocker load match switch. Bought it new in August.

Hmmmm. Go to the John Deere link below and find the Operators Manual pertaining to your serial number (range) for 4x20 tractors in North America. The lower serial numbers are for older models and the higher serial numbers are for the later models but I do not know the years for each range. Also, notice each manual is for all 4x20 series for specific serial numbers. I can tell you my 2007 4320 tractor did have a Load Match switch on the console to the left of the steering wheel as pictured in OMLVU17927 Operators Manual. My 2010 4320 does not have the Load Match switch as shown in OMLVU19619 Operators Manual. In addition, my JD dealer told me the Load Match switch was discontinued on the later model 4x20 compacts.

Was the Load Match switch put back in on the very latest 2011 models and not shown in the Op Manuals? Is your new 4520 cab tractor an older model? What is the serial number?

Manual OMLVU17927 for 150101 - 650000 shows the Load Match rocker switch on the dash board on left side of steering wheel.

Manual OMLVU19619 for 650001 - current has no Load Match rocker switch.

Manual OMLVU24813 for 840001 - current has no Load Match switch.

You might not have tried using it hard enough yet to see the benefits. I find that if I'm rolling down the road towing a manure spreader or loaded hay wagon, then going up hill... Full rpm, full speed in high range that the rpm's will drop to about 2k then the tractor speed will slow down. The rpm's never drop below 2k but the speed will drop off to keep you at a higher rpm limit then if you didn't have it on. I find that using it with fel in loading situation you really have to be working the tractor hard to get the benefit. Usually with the 4x series you will find that you spin the tires before the load match will cut in.

On the 3020 and 4020 series, as mentioned by others, the intent of the LoadMatch is to act as a "governor". It's benefit though, as I understand it from conversations with my local JD rep, is that it prevents the engine from stalling while under load (and engine speed). This is especially important with a turbocharged engine, where the turbo can remain spinning long after the engine is stopped. Having the hot turbo spinning without sufficient oil lubrication due to the engine not running just isn't good for the turbo bearings. Going along with this idea suggests that the engine should be dropped to an idle and allowed to "cool down" a short while before shutting it down to maximize the life expectancy of the turbo.

The following is from the 4720 Operators Manual for later model tractors w/o the rocker switch.
