I have a JD870 and want to order the manuals that will allow routine maintenance like valve adjustments etc. I have the operators manual and it does not cover engine valve adjustments. The Op manual does have an order sheet for other manuals -- there is an "engine technical manual" and several "FOS" manuals whatever that means covering topics such as engine, electrical, hydraulics, etc. What manuals should be ordered to allow reasonible maintenance. Should serious service work be needed, I would use a dealer or service shop. Thanks for any guidance. Ed

We have spun into engine technology which may be irrelavent in the tractor purchase decision, but it is fun. The vibration characteristics should be the same for diesel or gas -- the important thing is 2 vs 4 cycle. In a 4 cycle 4 cylinder engine there is a power stroke every 180 degress of rotation. This divides evenly into the 360 degrees of rotation so the power stroke impulses continue to enhance the vibration and have to somehow be compensated for. In a 3 cylinder engine there is a power stroke every 240 degrees and being it does not divide evenly into the 360 degrees of rotation it happens at a different rotational point each time and does not reinforce the vibration impulses -- it smoothes them.
All aircraft radial engines were an odd number of cylinders for this reason as vibration caused metal fatigue. Some that seem to to have an even number (like 18) were actually two "odd number radials" attached together. However, most of these Kubota's are land locked.

It was a 260 cu. inch. I can't remember to take out the trash but my head is full of meaningless factoids like that one.
I guess there were 289's also but this is the one I remember.

This is known problem with the BX 2200, just had mine replaced last week .After waiting a month for a replacement tank to come in, of course the dealer had the tractor apart when he found they had none in stock ,they were back ordered. Lucky it has not rained in a while and no grass to cut. Call you dealer ASAP and get in line. Good luck

We recently bought a JD 650 and have experienced problems with the tachometer needle going beyond the numbers on the tach face. Sometimes the tach works properly other times it almost spins around to the tach-stop. One dealer said its the cable another said it's the tach-head. Before I start taking it apart, anyone out there run into this condition before? It's my understanding that the 650 uses a mechanical tach. Thanks

If I could buy a B8200HST, loader,tiller and box scraper with 260 hrs. in good condition for near $5900.00 I'd grab it now. I'd think I was stealing it.

The Straight Dope on Draft Control on 3pt.<br>
<br>
You folks seem to have a good handle on what it is used for.<br>
<br>
Now let me give you an idea of it's effectiveness........<br>
<br>
It works on moldboard plows that are fully integral or semi-integral...........barely. I cannot find any other use.<br>
<br>
Sure there are many integral (3pt) implements it could be used on, but what's the point? Mount depth gaugeing wheels, and it is pretty much not needed. The gauge wheels will work better, maintain a consistent depth, and even though you may have a flat tire once in a while, they are still less trouble.<br>
<br>
The reason to use it on a moldboard plow is the fact that there is no really good way to mount depth gaugeing wheels on the front of the plow near the tractor. This is more of a problem on 4 bottom and larger integrel or semi integral plows because of the length of the tool. They usually have a gauge wheel on the rear. On shorter plows,(2 or 3 bottom) a gauge wheel mounted just in front of the tail wheel and to the left so it rides above the furrow (on land is the tech. term) and maintains consistent depth will work just fine.<br>
<br>
Changes in soil type, compaction and moisture levels of the soil, will give false readings to the load control shaft that senses the draft and raise or lower the 3pt hitch arms to keep draft within set paremeters.There is an adjustment on the tractor to compensate for this, but in reality, in some situations, this sensitivity needs to be adjusted several times each pass.<br>
<br>
If you are concerned with a consistent depth,( and you should be, because inconsistant depth with a moldboard plow, will leave an uneven surface)it is barely acceptable.<br>
<br>
On anything but plowing, it ain't worth a dime, and with a plow, it ain't worth much more, but you ain't got any other choices on a 4 bottom or larger plow either.<br>
<br>
I've been on tractors and plows for too many years to count..........that is my view.<br>
<br>

We are a JD Dealer. Haven't sold many of the blades, but they are well built. Don't know off hand about useing in conjucntion with mmm, but will lookinto it when I get some more free time.

The reason we sell so few of those blades here is the fact that they are 2/3 the price of an FEL, and customers usually go ahead and get the FEL, since it is so much more versital, and I know for a fact it witll work with the MMM. If yau ad the 3rd Hyd function to the tractor......More later

I have a KK Bush hog and it has worked fine. It was much cheaper than the JD and the JD dealer could not explain to me what the differences were.

I know they are built in Alabama but if I recall correctly, I think the transmission on my bush hog said "Made in China".

David Brown, who is known for making Aston-Martins, started out making tractors. I believe that both he and Lamborghini became interested in speed after years of doing well at building pull. I think Brown eventually bought Aston-Martin but I don't know how Lamborghini got into cars. David Brown is the DB in Aston-Martin model numbers it originally referred to the engines I think. Maybe my recollections need a bit of help here.

I too have watched three wheels spinning and wondered about a front diff lock. A related subject discussed awhile back is a differential between the front and rear drive trains. If I remember, during turns (the diff locks wouldn't be engaged) distances traveled by the front and back wheels are different and a differential would improve traction.

Defeating design gets tricky and creates safety issues and doing such shouldn't be recommended by anybody. A ballast box may improve balance but does little for side-hill stability. The idea of defeating the design contains an assumption that the loader frame and tractor mounts are capable of higher duty. Maybe, but few people probably know for sure.

In terms of the hydraulics, the question is whether it's a relief valve that is limiting the capacity. Many tractors have relief valves both in a system manifold and in a loader valve assembly and 3ph's. I don't know 455's and don't know if the valve replaced is the loader or other valve assembly.

On most tractors, you can hear the relief valve open when the hydraulics stall. If the valve can't be heard, then maybe something else limits the capacity. For example, pumps move less volume as the system pressure increases. A small pump with fairly low volumetric efficiency may simply not noticeably move a loader at low engine rpm, but the relief valve wouldn't open. Increase the rpm and maybe it's will move unless the load is heavy enough to develop enough pressure to open the relief valve.

If you're interested in pursuing the subject, I'd check the specs for the system hydraulic pressure and the relief pressure. A $10 valve and fittings would enable pressure testing on most tractors.

Guess I've been long on theory for awhile and it's pleasant to get practical for a change. I've never been certain how necessary PTO shaft boots are. I haven�t gotten around to buying one, and that�s been years now. I just keep the end covered with grease when a PTO shaft isn't connected and then clean it thoroughly before connecting a shaft.
