4300 hst v 3010 hst

[MJB]

There is a way to operate the rear PTO without an operator in the seat. I don't recall the specific order of events but I saw the procedure in the manual and verified that it works on my 4300. The procedure will not work for the mid-PTO however.

I would be interested in the steps necessary to run the rear PTO without being in the seat. I have a Kubota on which this is not an issue, but my curiosity has been peaked!!! [img]/w3tcompact/icons/smile.gif[/img] I must say too, that I have heard of this, and used lawn tractors with such a safety feature but they were really just lawn mowers. It makes sense to shut down a mower if the driver leaves the seat (most of the time). Not sure why from the compact size up that would still be considered useful/necessary???

Thanks,
Kevin

On the 790 you raise the seat, lift up the operator presence switch plunger and rotate a rod to keep the seat off the switch. I can't remember if you do this with engine off or on, PTO off or on? I've never actually done it [img]/w3tcompact/icons/smile.gif[/img]

Oil is being pumped.. just because the output shaft is not turning does not mean there is no drag on the engine. This is true even on a gear drive transmission. (Known as parasitic drag). You can test this yourself. Start any tractor (with a clutch) on a chilly day - below 10 degrees F.... engage the clutch while you are in neutral and watch the RPM's drop...

That's why I truly enjoy this board... great back and forth...

<font color=blue>I just hope I made the right decision with the 4600...</font color=blue>

Your Great grandkids will be still enjoying it...

with that nice direct injection Yanmar!

Farmer to be,

You absolutely made the right choice, because you liked the tractor best, and there were no bad choices mentioned. Enjoy your 4600 and be safe! Sounds like it will be easier to do with that operator presence system.


Regarding all the other comments. Now that you've made your choice, who cares if the engine is direct or indirect injection. At the displacement and rpms we're talking about, they both have good and bad points. Kubota and Yanmar both make great engines. Clearly JD has the more elegant clutch system for the pto's, and better ergonomics. Clearly Kubota has an awsome hydro system. Clearly green is the prettiest color for a tractor. Clearly orange or yellow are the safest. Clearly I'm glad that JD doesn't have anything that fits my needs as well as my 2710, so I didn't have to go throught the process you did.

You're gonna love the tractor!

Kevin,

[[[It makes sense to shut down a mower if the driver leaves the seat (most of the time). Not sure why from the compact size up that would still be considered useful/necessary???]]]

Coincidentally, it was just yesterday that my rancher/tractor-operator neighbor told me of someone who was killed when he lost both legs to a sickle-bar mower after he was bounced/thrown from the seat.

Not all "leaving the seat" is intentional.

I'm guessing that there are many stories of this nature to support a driver absent shut-off, ... if leaving the seat intentionally, and wishing to keep equipment operating, the override can be utilized.

I'm sure there is more that could be said about this (maybe it will be, on TBN) but I'm not unhappy to have this feature on my JD4700 [img]/w3tcompact/icons/smile.gif[/img] !

PS: And just today I watched another neighbor driving back and forth in his field STANDING UP (!) on his tractor,. He had a spray rig mounted, and I guessed he was looking for tansy or some other weeds. Looked pretty scary to me, considering these stories we keep reading on TBN. He would probably say his field is smooth, or he wasn't going really fast, or something. Maybe so, but if I'm going to be standing up looking for weeds, I'll be in the back of a truck (the springs/shocks are so much better), holding on to a roofrack, or I'll be WALKING!

I looked at my 4300 operators manual last night. The steps necessary to operatate the rear PTO (only) without an operator in the seat:
1. Start engine
2. Place gear shifter and range shifter in neutral
3. Lock parking brake
4. Get out of operators seat
5. Engage PTO clutch
6. Set engine RPMs to desired level.

If the PTO clutch is engaged while the operator is in the seat, the engine will shut down when the operator stands up. Hope this helps.

<font color=blue> just because the output shaft is not turning does not mean there is no drag on the engine. </font color=blue> I agree with that to an extent. There would be a certain amount of additional inertia to overcome due to the starter having to turn the input shaft of the transmission. I also agree that the RPMs will drop momentarily when the clutch is released. This would be expected due to the load placed on the engine to bring the clutch disk, input shaft, and cluster gears on a gear model up to engine speed from a dead stop. I don't agree, however, that oil is being pumped with the hydrostatic controls in neutral. My tractor, like every other hydrostatic I have ever seen, has a certain amount of hydro noise that is present whenever the controls are moved out of the neutral position. I don't hear any additional noise with the hydro in neutral. If the pump were moving oil in neutral where would it go? There would have to be a relief valve opening to relieve the oil pressure if the pump were to deliver oil to the hydro motor and the motor was not allowed to turn. The parasitic losses would be much higher for a gear transmission if started with the clutch engaged and the transmission in neutral due to the cluster gear having to turn in the transmission oil whenever the input shaft turns. Isn't this board great?[img]/w3tcompact/icons/smile.gif[/img]

Larry,

<font color=blue>Not all "leaving the seat" is intentional.</font color=blue> Certainly true in some cases. For me...well....I plan on making VERY good use of the seatbelt on my tractor. Thus planning that the only time I leave the seat is when I intend to.

I guess the main point here is safety first though, and obviously John Deere has a very valid safety feature. And as long as there is an intentional override mechanism then their mission has been accomplished. Good for them.
