Is a 2955 a good tractor ?

Is a 2955 with a cab a good tractor ? What were the typical problems with them if any ?

 

[Buster]

Good friend of mine traded his IHC tractors for a 2955 and a 3155 John Deere, have not heard him complain about either one and he covers alot of ground with them.

Buy a 4240/4250 instead,,much better systems,more dependable units. I can't say anything good about a 2955...I cringe when they come to my shop....I know a lot of people on here are proud of them,,not me....

 

[JD720]

Thats what I am afraid of I know the 2840 was probably the biggest P.O.S. that Deere ever made and that was where these started I had hoped they got better but apparently not. Thanks

jd720 you must not have spent any time around aJD2010 2840 was head and shoulders above a 2010

I had a 3155 The only problem I had was hydraulic. If you use it to run orbit motors the oil will get hot. I also had a valve go bad that bypassed oil and had both hydraulic pumps replaced John Deere had it split with the cab off twice Deere company helped figure it out they had a bill of $32,000 That I paid $12,000 of but The dealer and John Deere split the rest and called it deere school expense. I thought I got took. I should have let them have the tractor. It did work when they were done The valve that was bad was on the outside of the transmison and cost $80 I used it 4 more years and traded for a 7830 The Trade value was still $32,000 But not at that dealer.

These models of Deere utility tractors have some very weak systems and ideas, like "all" the hydraulic flow goes up through the shifter cover before it heads to the main pump, the high/low shift is a basic add on feature with light bushings and seal rings, the brakes are not "power" brakes and they give a lot of trouble, especially if the wrong oil is used, on the ones with sound quard bodys the shift mechanisms are "adapted" to fit the cab and the scv's are mounted under in a nasty place(just try to keep your shirt dry when removing one) ....and many more sub-standard things,,the Waterlou systems are much more dependable,,and repairable,,and again I know a lot of people are proud of them, and that's okay with me....

Whats the diffrence between a 2955 and a 2950? Our 2950 has barley given us trouble at all.

 

[JD720]

Never owned or even drove a 2010 but after having the Hi-Lo go out on the 2840 and was fixed then it wasnt long and the steering cylinder failed and dumped oil in on the clutch and flywheel I sent it on its way to a salvage yard the 2840 was just one problem after another.They are not even close to the tractor of the 4020 I replaced it with the 4020 has cost me very little over the last 15 years but now I would like to move up to a cab tractor.

 

[rexhellwig]

They are OK for PTO, light drawbar work, cultivating, and small square baling.

They're not a good loader tractor. But everyone wants them to be.

If you used a Dubuque or Mannheim to run hydraulic motors or other high flow loads. Without the optional ported filter cover return that Deere sold for such applications.
Yes you would wreck the hydraulics in a hurry.Running the front pump without enough oil does that.

b&d
True the ported filter cover helps hyd operations. Tim s is correct as the Waterloo hyd system design and operation is way above/ahead of the Dubuque/Mannheim utility tractors.

IMHO a hyd orbit motor will shorten the life drastically of any of JD's closed-center hyd systems because of the ADDED HEAT the motor causes. Just run a JD 700 or a Vermeer R23A hyd hay rake on a JD tractor for a few hrs and reach bare handed to unplug the orbit motor hoses and you'll agree.

 

[buickanddeere]

Most oil coolers and hydraulic oil reseviours I've seen need a good cleaning. As the layer of oily mud insulates the heat in instead of letting the heat disipate out.
Hydraulic oil and seals should not be damaged running at temps up to 200-220F. Such temps feel too hot by "normal" hydraulic standards found on loader hydraulics.

A hyd loader function will not begin to heat up the hyd oil any where close to the temp of the operation of an orbit motor!!!!!!!! I agree a clean oil cooler helps but doesn't cure the heat created by an orbit motor.

To my thinking an working orbit motor is producing heat buildup very similar to an internal high pressure leak on a closed-center hyd system.

If for frt end loader use the dry traction clutch is not as durable as the wet traction clutch in a Waterloo tractor

Figuring if a 10HP hydraulic motor was running at a hydraulic system efficency of 85%.
There would be approx 1200 watts or 4100 btu/hr of heat disipated into the oil. In addition to all the other souces heating the trans-hydrualic system.

Thanks for confirming that a closed-center hyd system isn't a good choice to power a hydraulic motor because of the heat created !!!!!!!!!!!!!!!!

 

[buickanddeere]

Any pump , motor and associated lines/valves will have losses.
Come to think of it I missed the pump and line losses on that 10HP motor example.
Heat dissipated into the oil would be closer to 3000 watts/10,000+ btu/hr.

I think the btu per hr heat would be directly proportional to hyd sump size and oil cooler size & cleanliness not to mention the ambient atmospheric temperature.

 

[buickanddeere]

Heat generated or heat dissipated?
Heat generated is proportional to the amount of
oil pumped, pressure and "friction".
Heat dissipated is ambient temp, lbs airflow and
heat exchanger surface area, hx internal flow, hx
material heat co-efficient and "dirt".

 

[Tx Jim]

The more factors you bring up the more apparent it appears that a hyd driven orbit motor shortens the life of a closed-center hyd system.

 

[dieseldoc]

if closed center is a bad system whats the best way to run a 7200 vac planter.

(quoted from post at 19:32:39 03/11/11) if closed center is a bad system whats the best way to run a 7200 vac planter.

Closed center hyd systems aren't necessarily bad but heat shortens the life of any hyd system and the life of the hyd oil.

I think a running an orbit motor on a closed center system will affect it similar to having an internal high pressure leak. Plus an orbit motor defeats the real purpose of a closed-center system because the hyd pump must pump constantly to power the orbit motor which increases pump piston wear.

Also the amt of load on the orbit motor affects the amt of heat it emits.

 

[buickanddeere]

A closed center pump varies it's flow to match
the load. An open center pump operates full flow
all the time.
Which is better, it depends.
In any case a hydraulic motor is a lossy way to
drive machinery. The losses are tolerated for the
many advantages in price, mounting, control etc.
If anybody has noticed, trains operate with
electric drives. That's a place where power get
put to the ground/rail.
At one time DC and now AC drives. Heavy off
road equipment such as trucks and even crawlers
are electric or going to electric.
Once upon a time IH introduced electric drives. Unfortunately farmers among most other people.
They are terrified of electricity.And at best are
uncomfortable with something they can't "see".
Hydraulic drives are used on small intermittent
use equipment where the heat and losses cost less
than an efficient drive.
