Assessment of Deere 4310

Love my 4310!!! Moved a load of bales today, what fun!!

I have to really think when I hear how much trouble folks have finding the keyhole. Sometimes I am glad I am not handicapped with vision!! (Its real easy to find if yer blind!)

"My fuel level gauge has never given me a correct reading" /forums/images/graemlins/confused.gif

Must be something wrong with my JD as the fuel level is very close to what is displayed on the dash indicator. I really wish Deere had provided a working oil pressure gauge and ammeter instead of those stupid warning lights.

Just curious, with all those proud 4310 owners on this forum, why has no one yet posted a review of that model?

rockyridge,
what size bales are you dealing with?i always wonder if a 4310 can move round bales easily and efficiently?

</font><font color="blue" class="small">( This is probably a dumb question, but what is a 'e-power reverser' and how does it operate compared to the hydro? What wears out on the e-reverser? )</font>

A 4310 gear tractor has four gears and a clutch with the clutch being actuated by the operator. A system used since the beginning.

A 4310 ePowerReverser has four gears and two clutches, one for forward and one for reverse. These clutches are actuated by a pair of proportional valves controlled by a electronic controller (the "e" part in ePowerReverser). The clutch choice (direction of travel) is determined by the lever on the left side of the steering wheel. Once the lever is placed in the forward position (for example) and the clutch pedal released the controller sends a signal to the forward proportional valve. The proportional valve then sends regulated hydraulic pressure to actually engage the clutch. When there is no hydraulic pressure the clutch is held in the disengaged position by a return spring.
Boiling this down, a ePowerReverser is a conventional manual transmission with a basket of electronics thrown in. When it comes to service there is potentionally two clutch packs to service instead of one. More often than not only the forward clutch needs service but seeing how you're splitting the machine it's often wise to change both while you're in there.

The 4310 eHydro also contains a couple of proportional valves but in this case they're controlled by the directional pedals. The directional pedals send a proportional signal to the controller (the "e" part again) telling the controller how to position the swash plate which determines the direction and speed of the tractor. Because the engine is "fluid coupled" to the drivetrain Deere puts MotionMatch, LoadMatch, and cruise control on the eHydro models, the "eMatch OS". The eHydro offers, in Deere's words "A wiser use of power. Superior reliability"The wiser use of power is in reference to LoadMatch which automatically slows the eHydro transmission to maximize power and virtually eliminate stalling.

With the eHydro the "creep" rate can be selected with "MotionMatch". You can select a slow decel rate for precision work or a fast decel rate to increase productivity.

dmp437...thanks for the technical stuff. I get the picture even clearer now. I think I'm going to have to test drive an eHydro soon to see the precision and feel of moving the machine with it; this isn't necessary at all times of course, but when I need it, I really need it. (Like when inching up to your pickup to dump dirt in it.) My coworker (who bought my old JD755 hydro) drove his cousin's 4310 eHydro machine, and he didn't like the lack of direct hydro pedal control; the eHydro electronics always seemed to react artificial and 'second guess' exactly what he wanted to do. MotionMatch sounds interesting, though; I can see where it would be useful, especially for beginners. I'm just a little wary of it, because once I got used to my 755, I could always move fast and smooth, and I didn't need Intel-Inside to figure it out for me. Maybe if JD would offer a third setting on 'MotionMatch' for 'exact control' these situations it would be useful.

Denali 60,
John Deere is doing just what you mention. On the new 3000 series tractors there will be improved electonics to improve substantially the vague pedal feel. There also will be a fully adjustable roll out feature to allow for subtle variations in movement. This should work really well with LoadMatch and likely directly addresses the issues you state.

jcmseven: Thanks a TON for the post! Both for the 'vague pedal feel' confirmation, and the upcoming fix. Now with this information, I can make a good decision, which would seem to be wait for the 3000 Series. Wow. I LOVE the Internet!! /forums/images/graemlins/grin.gif

Danali60,

I can offer direct, personal experience in the transition from a JD755 to the 4310 with ehydro. I too was disappointed with the pedal response. I wouldn't characterize it so much as vague. More like delayed. During operation, for instance going forward, the pedal does not feel significantly different on the ehydro vs. the 755. Pedal resistance is similar enough and changes in speed are also similar enough. Where I notice a difference the most is changing directions, or just starting off. Press either pedal and there is a slight delay. This is something you can get use to when starting off in forward or reverse but the transition is more difficult when changing directions. A couple of cases in point:

When mowing with the MMM, I make several direction changes. With the 755, the change in direction is instant and smooth. With the 4310 ehydro there is a delay. When you release pressure on the forward pedal, the tractor comes to a stop smoothly but hit the reverse pedal and there is a slight delay. Same thing going forward again. This is annoying but I'm getting used to it.

Changing directions on a slope is the worse. On the 755, I could creep down a slope and hit the reverse pedal to instantly back out at the exact point intended. I'm not talking a tire spinning reverse here, just creep in, hit the reverse pedal to stop forward motion and back out. This is impossible on the ehydro. You must use the brake to keep from rolling forward further than intended.

I had problems with my ehydro that have been corrected. When the forward pedal was pushed to the end of its travel, the tractor would come to a complete stop after several seconds. It was just as if your foot had slipped off the pedal but it was still pushed full forward. Take your foot off the pedal, wait a couple of seconds and you could resume operation. The dealer replaced a bad potentiometer. When I got the tractor back, the problem was fixed but now the forward pedal needed to be pressed about half way down before movement started. Top speed was slower. Back to the dealer for an adjustment. Everything seems to be acting "normal" now.

755inNY: Thanks for the info. I guess my plan now is to either find a used non-e hydro with loader and backhoe, or when possible, check out the 3000 series and see if they've improved this situation.

Wow, hold om! The ehydro will be improved with the 3000s but it is a huge improvement over the non e version! The biggest issue would be a bit of "getting used to it" In real life, it is awesome...
