2305 hydro loss power

[dbrink2305]

Hello everyone. This is my first post on TBN. I am a member of many forums but not one to post. However I am in need of some help/info this evening.

I have a 2006, 2305 with only 365hrs. i have the 200cx loader, iMatch, tiller, sprayer, spike aerator, rotary broom and the mighty green 60" 7iron MMM. Yes I know. Just add to have the better deck. Converting was easy fyi.

Anyways thats what I own. First I would I to mention is my tractor befor the 2305 was a 2002, 455. It had the same attachemnts as the 2305 i own now. However it had 1755 hrs on the meter when i traded it in. It had only 2 minor parts that i replaced since i owned that little best. I wish I still had it.

My problem to date is the hydro. The hyrdo has very little power( travel speed, pulling). The reverse speed is powerful and responsive. when going forward the hydro whines, squeels. I believe its the relief valve? The power steering is slow and unresponsive this time. Either way this is the second time it has done this. Last year spring 2008 this problem arrise at 250hrs. Dealer put in a new pump and relief vlaves. Problem still wasnt addressed properly as the forward speed was slow. They said something about pressure needed adjusted. Then it worked like new. untilll

oil and filters are good and such.

There is more to the story, and i really would rather not expand as the dealer is poorrrr. But what i really need to know is what is causing this to happen. First i know its not operator error. My 455 shows I know how to operate my machines. I mean the 455 didnt even have low range.

Anyone have experinceed this before? any input would be helpful as the dealer is not. I still have 2 months powertrain warranty left. O btw a input shaft was replaced under warranty only after the origianl pump seized when in use. The snap ring groove wasnt machined deep enough. Was replaced under warranty only after problem arrised. Anyone have this problem?

p.s. My dealer is not the best. Actually the whole community knows this but next dealer is over and hour away...


Respectfully
Dan

Is it possible to use the other dealer, or at least talk to them? If so I would take the receipts on what the first dealer did and have them look at it.

Does this machine have i Match on it? if so, turn it off.

With so little time left on the warranty, I would be calling the area JD representitive right away. Something isn't right there, and hasn't been all along, and you want it fixed, or replaced under warranty. I've heard of the fan cooled hydro's losing some power when they get warm, or hot, but I've never heard about, or experienced the problems you talk about. I've owned a few, both fan cooled, and liquid cooled. Make sure you get the problem recorded at least with JD! Good luck.

Thank you for the info friends. Take it to another dealer wont do much. All the 5 dealers around me are the same owners and such. These particluar dealers dont give you the time of day if you are the average person and dont trade every year.

As far the the cooling for the hydro pump, well that makes sense. The hydro is strong when cold then gets week the more it is used. It is fan cooled. My other 455 wasn't fan cooled but cooled by the radiator, and never a problem.

This tractor is ran for long periods at a time. Used for industrial mowing. 5-8 hours a day. I'm sure the dealer will have a reason to denie the warranty.

I'll report back, should you guys wonder what the outcome is this time.

I might trade her in for the kubota, but I'm sure warranty will be denied should I adapt their commercial decks.

Anyways, Thank you again for all yours help. Have a good day.
