Glasgow MT | OK so ive heard the argument about powershifts why is there so many people mixed about them what are yalls thoughts |
|
| |
|
West Central Indiana | Which one? Are ou talking about the 8 speed, the 15 speed, or the 16 speed? |
|
| |
|
Glasgow MT | well my 4020 has the 8 speed and my 8300 has the 16 speed |
|
| |
|
| There is no comparison from the eight-speed to the 16 speed powershift in a John Deere. |
|
| |
|
| 16 and 18 are nearly bulletproof, 8 and 15 were solid transmissions but very rough imo. Of course the 15 was a big improvement from the 8. |
|
| |
|
West Central Iowa | Here is why I am no fan of the 15 speeds, this is a 4955. It has issues everywhere from the rear of the engine on back. 8072 hours.

Glasgow MT | i really want a 4440 with a 15 i just really like powershifts for planting and plowing but ive heard a lot of argument that powershifts are horrible and these are people with quad range transmission so i dont understand why they would like those so much we had a 4440 with a quad range and i never really liked it |
|

|
Glasgow MT | clutches or what |
|

|
Geuda Springs, Kansas | 4450s had. 4440 were 8. |

|
Geuda Springs, Kansas | It's kind of like buying an ultra shift in a semi. Most truck drivers will not like it because it makes them feel like a man to shift and jam gears. |
|
| |
|
Schlegel Farms, Hagerstown Indiana | That looks expensive. |
|
| |
|
Glasgow MT | oh yea thats right 50 series had 15 speed and oh ok its a ego thing vs comfortably |
|
| |
|
South Ga | If I had to choose between an 8 speed power shift and a quad-range I would take the quad every day. 8 sped always seems to be a little too fast or a little too slow. I would rather have the 15 speed power shift over the quad though without a second thought.
I go through Covington a few times a year going to Lawrenceville, there's not much room for farming in that neighborhood. I bet it's a pain going down the highway with equipment around there. |
|
| |
|
Mount Vernon, WA | That output planetary pack looks VERY expensive. BTDT. |

clutches or what
Lots of issues in a lot of different places, clutches wouldn't be so bad, but this one needs lots of expensive hard parts. See the burnt spot in the B2 section of the planetary pack? That is what happens when the B2 ring gear breaks into 2 or 3 pieces. This thing had problems with the C1 & C2 clutch, the input planetary, the rear planetary pack, the PTO clutch, the PTO brake, the MFWD clutch, the reduction gear train, brakes are shot, and a bearing out of the trans pump, ruining it. My first estimate using all new OEM parts put the total repair bill at well over $30,000. We are doing it with some rebuilt parts, some very good used parts, some new OEN parts and some new aftermarket parts. Still going to be way too expensive, but the owner insisted on fixing it. It is getting every bearing and race replaced also. |

Yep, I hobby farm a little, NO way did I want any green one with the 15 speed PS......I now own a 7120 MFWD. |

Freeburg IL | I have worked on far more 15sp deeres than 8sp deeres in my shop. 15s just dont seem to be as tough. |
|
| |
|
Geuda Springs, Kansas | Big deal! It's an old tractor. What do you expect? |
|

| before you buy any new tractor just say DIRT Pan and warranty see what they say-------------------------dave |

Camp Douglas Wi. 40miles nw of wi. dells | Have 3-8410Ts, 1-8110 FWD with 16 speed power shift, old 4840 with 8 speed power shift that runs the grain cart feeding cattle year around, not a penny spent on transmissions.
9400T with quad range that come apart last spring under full load, when they had it apart put both dampnerers and inner cooler $25,000 fix. Wished it had power shift.

central Indiana | that 4955 did not come from SC Indiana did it? there was one that was advertised with 8000 hours that had 15000 on it |
|

Northeastern Pa. | I have driven the 8 spd and was taught how to shift it. The worst thing Deere did was put the big handled shifter on it. I always wrap my hand around the rail and shifted the 3020's etc. with my thumb. Smooth shifts. The 4250 15spd. basically did the same. Our 4250 had 10,000 plus hours on it before it need a clutch pack replaced. A manual trans would have needed at least one clutch job by then. So like anything if they are treated right they are good. I do remember when a factory rep. was at our local Deere day when the 50's 15spd came out he said just shift anyway you want without the clutch. Reverse to forward and back whatever. That's a crazy statement. Depends on load and rpms to me. |

SE MN Still in Pothole Country | Never had a 3020 or 4020 Powershift. Had 4640PS and now a 4440PS. 4440 now for planting, small grain cart, and used to spray with it. Now spray with 4440 Quad because it has the narrow tires on it. 14.9 x 46. R-E-A-L-L-Y prefer Powershift the way I use now. Considering dualling up the 14.9x46 and putting on the Powershift Tractor. Also have 7140 Boxcar Magnum. Even with 18 speeds could use one more between 4.3 and 5. But not the country's biggest problem.
Around yard with the 8 speed PS you learn to go right to 3 or 4 at low throttle and no clutch. If you try 1 or 2 and think you are going to 3 or 4 you get the old stop and go like an 806 with dump valve on TA adjusted wrong! |

No, the present owners dad bought it new. |

Northeast Iowa | I'm sure with tractor having a blade on it, it also sees more forward and reverse than a normal tractor out in the field working |

You forgot the 18 speed. |

Eastern North Carolina | I like the power shift cause I only have one leg. Guy that used to bale my hay liked the power shift cause he didn't have any legs and only one arm (the left). He ran a 4250 and traded up to a 7700.

Northern California | Do you want to do mine next?? 4560 8,000 hrs., New JD reman engine. Toast 15sp PS. |

Southern Nevada desert | My neighbor has a 4560 with a 15 speed, they have called me down twice to troubleshoot it when it quit, both times no oil. Never had the trans oil changed in the first 10,000 hours, about 3000 hrs on filter changes, decent maintenance the last 5000 hrs or so. Its over 16,000 hours with no problems at all as long as it had oil in it, my other neighbor has a 7730 power quad that quit at 8.000 hrs, about $10,000 to fix. I would take a 15 speed any day over the 7800 19 speed, that has been a money pit on mine.

Glasgow MT | depends on which side of the county you go through |
|
| |
|
| 8000 hours is a lot. How many hours would you expect to get out of a 30 year old tranny? How tractor is used also makes a huge difference in life expectancy. The 16 speed power shifts if taken care of seem to go a lot further than 8000 hoursvthough. |

Manitoba, Canada | We have had good luck with powerquads. Our 4250 PQ has around 14000 hours on it and the clutch and transmission have never been touched. Yet. No sign of any issue but I've learned that doesn't mean it will last the day. I wouldn't want to count the number of times the clutch has been pushed and the transmission shifted. I have never driven a 15 so power shift so I can't comment on it at all. I do like the PQ though.
Your last few comments describes part of the reasons we hear horror stories. Not always, but sometimes. Just because a person can shift like that doesn't mean we should. Some people can drive equipment with known weaknesses and never have an issue and the next person can drive a bulletproof design into pieces long before it should be. Common sense goes a long way. |

depends on which side of the county you go through 36/81 Last year there were a couple of fields of soybeans between Jackson and Covington, they laid out this year and there was about 4-5 acre patch of corn around Walnut Grove is all the row crops I've seen going that way. Lots of pasture and hay though. |

West Manchester Ohio | We have a 15 in a 4455, do you think it's hard on it to pull it into neutral without clutching from say like 8th or 9th gear? |
|
| |
|
SE MT | Have two 4630s. One is quad range, one 8speed powershift. The quad range is hands down a better farming tractor. More speeds, less hp loss in the trans. The p.s. is better at everything else. Have around 15,000 to 16,000 hours on the p.s. tractor, trans never opened. Engine only overhauled a year ago. If I could have only one it's the powershift easily just for ease of use, and anyone can drive. Good trans to start the wife or kids on
Also have a PS in a 2520 nd that is also still original with around 7000 hours on it. Those transmissions while sometimes rough or a little crude get the job done and will probably outlast a couple deere IVT transmissions

If you're not careful, you can get a pretty good jerk doing that. If you can do it without getting a good jerk, go ahead. It's probably easiest to just push in the clutch, and coast to a stop. I have no problem with shifting a 15 speed from forward to reverse or to neutral, etc., without using the clutch until you start jerking everything. Not wise to do that, IMO. |
|
| |
|
Northern California | Yes, I wish it was in Iowa. Only options here is local JD dealer or do it myself. That's why it's just parked for the last year. |
|
| |
|
| two things that will help the 8 speed is boost the trans pump pressure to 195 hot oil and use the 10 micron ar 94510 filters. clean oil is a plus and the higher pressure helps avoid slippage.there is an adjustment for speed or aggressiveness of shift on the bottom side of the clutch valve you can adjust to your liking. |
|
| |
|
SE MT | I'd have to take the rockshaft housing off to get to the trans pump to change the pressure wouldn't I?
Good to know on the trans filters! The shift firmness isn't bad on this trans, the 8th gear whip is bad enough! I just clutch before I shift. |
|
| |
|
Southern Pa. | No need to pull rockshaft. A repair manual will guide you through it. I generally don't go above OEM spec. on transmission pressure unless I want to twist it's tail. AR94510 filters are recommended for cleanup purposes after something fails like brakes, clutch packs, etc. Not sure Deere recommends running them all the time, though. Hyd. flow might get a little slow in cold weather. Maybe someone else will chime in on that.
I also insist on clutching from 7th to 8th. |

|
| AR 94510 are the regular filters AR 98098 are the clean up filters.
