Jerry,
Maybe one more day of staying home w/the tractor fever you would feel better. /w3tcompact/icons/wink.gif

You got to admit its a different world now w/ your new tractor,for the projects are so much easier also fun.

Take care and stay safe.

<font color=blue>come off rpms 3 time for no reason. It just kind of almost died and then it would come back just as fast</font color=blue>

I'm curious. Were you accustomed to using an HST transmission before you got this tractor? When it lost rpm, did you have the pedal down pretty far? And when they came back up, had you let off the pedal a bit? In other words, I'm wondering whether you know that the pedal doesn't work like an accelerator; it works more like a gear change. When you need to push harder, I think there's a natural inclination to push farther down on the pedal, but that can only give you more speed, not more power. In fact, it gives you less power and will sometimes bog down the engine.

jfakerj,

I leave my JD48 on the tractor most of the time. Its just so danged usefull doing things. Its pretty easy to take on and off. I think the key to the process, as the manual states, is having a flat and firm surface to place the backhoe. You might have to adjust the backhoe plates to get hoe back on the tractor. I had to adjust things a time or two. I finally got it just right, or so I thought, and the dealer changed my setup when he had it in to fix the FEL setup. He thought he was doing good but I still had to adjust the plates. I hope to take the backhoe off the tractor in the next month or so and it will be interesting to see if I have to adjust the plates again. Hopefully I got 'em JUST right!

I think the rock shaft still has hydraulic pressure. I don't think the Power Beyond Kit effects the rock shaft. If it did you would not be able to get the BH off the tractor. I remove the tractor-backhoe hydraulic connections after mounting/dismounting the BH. At least that is the way I remember it!

Just don't forget to turn off your engine and bleed the pressure from the hydraulic lines before connecting/disconnnect the backhoe.

I'm glad Bird mentioned the HST pedal operation. I remember someone having the same problems a while back and it sure sounded like the same issue. But I'm not an HST driver so I don't really know for sure.

Later...

No, this is not a problem of not knowing how to use the hst pedal. The rpms were about 2200 with very little load on the engine and all of a sudden the engine almost dies and then as fast as it almost died it picks back up. Just like lack of fuel for a split second or if it were a gas engine-lack of spark for a slit second. It happened all 3 time when the tractor was leaning to one side or front to backor visa versa.
My 47 b/h uses the power beyond. You unhook the rock shaft after the b/h is in position and hook in the b/h where the rock shaft was - under the bh seat, along with a return hose. That's why you have to take the pressure off the rock shaft because it's being unhooked. At least that's how mine works. So on mine there shouldn't be any pressure to the rock shaft after the bh is hooked up.

In this forum I said my hst forward pedal was sticking. When my pedal sticks it's when the engine starts to lug and I'm releasing pressure on the pedal with my foot to allow the trans. to shift or slide or what ever it does into a lower gear for more power (proof I'm using it right). When the pedal sticks and does not come back up the way it should it lugs and kills the engine. If I'm fast enough with my foot, when I see this happening I can hit the reverse pedal and this forces the forward pedal up, the rpms come back up and I can resume what ever I was doing in a lower gear.

Jerry, I don't know what could be causing the pedal to stick; linkage too tight or lack of lubrication? At any rate, I'd have to talk to the dealer and get that corrected right away.

As I posted when I was looking at this tractor, it's used(about320 hrs now). So I guess I'll get under there and take a look myself. I looked a little today and noticed a bolt is loose on the foward pedal allowing quite a bit of play. Don't know if this could be the problem or not. I'll take care of the bolt tomorrow. I already put some lithium grease around the pivot points. I've been pretty buisy cleaning the thing up. I don't think the previous owner believed in cleaning anything. He did believe in grease though. I pressure washed most of the grease out and off of the the fel and bh and regreased the fel today. Will regrease the bh tomarrow if I have time. The build up of old grease was unbelievable. Every time I'd get on the tractor I'd get grease all over myself. Well, on to cleaning the engine compartment next. Then I'll have everything clean and can dirty it again myself.

Jerry,

It sounds like you are sure having fun with your new toy---er---tool. /w3tcompact/icons/smile.gif

On the engine dropping power, were you leaning forward or far to one side when it happened? There may be a safety switch in the seat that is trying to keep you from being injured. That happens to me with my lawn mowers. It may not be it, but it would be a simple fix. You can probably find more information about it under "Operator Presence System" or some such in your owners manual. Or a quick call to the dealer.

As a matter of fact the tractor was leaning forward and to the side each time this happened. You could very well be right. The switch under the seat may have had just enough pressure released from it for that split second that it made the tractor sort of hiccup. It only happened on very rough ground. I'll check the switch to make sure it is contacting like it should.
Thanks

Jerry

Jerry,
I posted this once before, but it might be worth repeating that my JD mechanic warned me to turn off the engine while pressure washing and keep water out of the air intake. He said that due to the high compression of these engines even a minute amount of water getting into the cylinders can bend rods. Good Luck
