Dk45se weak hydro?

[tractorsam]

Thanks for the replies so far. So the first thing I'm taking from everyone so far is that even though it has more power than the CK don't expect it to climb the hill in Hi - duly noted. Also I believe it has loaded rears and that isn't helping me here, and the KL401 loader.

To ksbrdmkr - this is where my concern comes from, you say going up a hill your engine will pull down from 2500 to 2000 or so. Mine will pull down from 2500 to only 2300 or so in forwards before it seems the transmission really starts to slip, reverse acts much more like you described.

I was using the tractor last night (for the first time - it's her tractor, not mine, she just showed me the issue in high) and noted a couple of things in medium. First - forwards seems to be slower than reverse by about 25%. Secondly (and yes, I know this isn't good for the tractor and I was only trying to test it) if I hold the brakes (not ridiculously hard) and try forward the tractor will not move, if I try reverse there's no stopping it.

Can the service manual be purchased through a dealer?

Thanks, Sam

Yes the service manuals are available through a dealer- or were anyways, a couple years ago when I purchased mine. These machines have changed very little until the tier 4s, I imagine. I seem to recall paying ~ $165 for service and parts manuals from my dealer that is 3+ hours away from me. Hopefully you have a fairly local dealer you can establish a relationship with. If not, call these folks: Michigan Iron and Equipment Morrice, MI. Doing a quick search on their web site I do not see a manual listed.

My DK45HSE weighs ~ 6500 - 7800 pounds depending upon attachments and acts similarly to K0ua's on post #9. Since my tractor never travels on a level surface, I never use hi range except to test operation.

Hmmm. I didn't think they'd be that heavy. I didn't haul it home so I never got a sense of the weight. Thank you.

I have loaded rear tires (+800 - 900), of course the loader and then attachments. ROBB weighs 710, grapple bucket 550 and a 3PH weight box @ 1200 and various lesser weight attachments. I continuously carry an assortment of chains and a good sized tool box that is full, plus other mods. It all adds up depending upon use. According to a 2011 Kioti brochure, base/stock tractor weigh is ~ 4000# plus loader/bucket, backhoe, etc.

Hm... Fwd should be somewhat faster than reverse. Look at the label on the front side of the left fender about by your left knee when seated on the tractor. Yes paper manual available at the dealership. We all downloaded digital manuals when they were available offshore. They are EX series manuals, not DK manuals, so a foreign version of the manual as the tractor is setup in Australia, but they are close. I don't think that site is up now though. I could be wrong.

An update / hopefully a conclusion to this. The dealers tech was out today and agreed it's not right. He checked the forward and reverse pressures on the hydro and they were lower than spec but the same. Charge pressure was good. A little investigation into the slower in forwards issue revealed some loose hydro linkage that was preventing full travel in the forwards direction. Correcting this has put the travel speeds right and now I can lug the engine in forwards. So all seems to be well with the world. Thanks for all the suggestions. And I won't be driving it up the hill in high range any more

Congrats on the easy fix. Should give you many years of work.

For most all tasks medium range is suitable, except for those when low range is needed, and usually that is obvious. High mostly gets it going when on road and flat and fairly constant speed. Can't shift between ranges when moving either, in case you were wondering.
FWIW, I suggest always putting it in a range and setting the parking brake, even on level ground, in addition to lowering the FEL's attached implement to grade before leaving the tractor.
Here's another way to see if the ranges are working and trans too. On a hill in forward, let off the forward pedal and it should come to a complete stop all on it's own. If not, the trans may need further attention.
IF you get any kind of loud squeal when in reverse there is a known fix for that particular issue - you can find it by doing a search of my posts from back in 2010. I'm NOT the author, but I did help find the fix.
It's nothing to worry about, doesn't cause any known damage, it's just damnn annoying if its present on a particular DK Series machine.

Enjoy that tractor - they're excellent workhorses.:thumbsup:
