Backhoe One more backhoe question....

[steve0413]

New DK45SE w/cab and 2485 backhoe.

I have already had cases where the boom has had trouble lifting the loaded bucket (red clay gravel) from a 5-6 ft deep hole. Fluids are fine. Running engine at 1800-1900 rpm. Is this normal or should I expect more power than this?

Also, should it be powerful enough to reposition the tractor, i.e. lift the rear and swing it to one side or the other?

I am a new operator admittedly but I was expecting more power than this.

Maybe more rpm?

Thanks.

I don't know about yours, but the bh on my ck30 is the strongest thing on my tractor. Lift the front end off the ground or the rear end..

And a 24" bucket full of clay is no problem..

Would be great if you could post a video on youtube or something, I'm always anxious to see video of people's described problems.

Your hoe should be able to lift the back of your machine with little effort. Your hoe should be able to pick up the better part of 1000lbs with little effort.

A full bucket of dirt should move the same as an empty bucket of dirt. You should be able to easily pick up rocks 2-3 times or more the size of your backhoe bucket (assuming you are not running a 36 inch bucket).

Sounds like a problem.

Is your loader strong? Can it lift the front of your machine? First thought is always pump, even if valving is limiting flow, power should still be there. Maybe your hoe's valve body's pressure relief is set incorrectly or something has it stuck open and oil is being diverted.

If new machine just call dealer and let them sort out.

Good luck,
Joel

Steve,

I have the same unit and tractor - almost.
I dug a test hole 4'x4'x5' deep in heavy clay no problem.
I tend to run a little higher on the rpms - around 2000-2100.
I haven't used the unit much - but when taking it off had no problem
lifting rear of tractor - by accident.

Look for crimped or damaged lines. Hoses are tight...

What size bucket do you have on it?
Lifting the tractor off the ground to reposition it is very dangerous and would not recommend doing this.

As I think about it, I don't think it lifts the front off the ground as I dig.

Stout hoe, but a bit of a bucking bronco..

For the record I agree with Rick on the repositioning with the hoe, I think it also probably does a number on the bushings.

It's an 18" bucket. Thanks for the warning on the reposition question. I'll avoid doing that.

This problem with the lifting seems intermittent. I'll keep an eye on it and see if I can get more specifics. And I'll try a video as well if I can figure out how to do that. Bottom line is it just doesn't seem as strong as I thought it would be.

Thanks.

You are correct, it should not have any trouble at all lifting a bucket of clay from 6ft down. An 18 inch bucket of clay cannot weigh much more than 300-400lbs and that BH should be able to easily lift that. Something ain't right. I rather doubt that the RPMs are the issue either.

 

[steve0413]

Thanks again. I'll have it checked out.

Also, yesterday I started greasing it and the third zerk I added grease to broke. The nipple just broke at the base without any pressure on it. No big deal, except I went to NAPA and O'Reily's and neither had one with the correct thread. Are these odd-ball zerks?

I'm not sure who makes the KB2485 but Kioti tractors themselves do have some odd ball sized zerks. Did you try metric? There is also some odd British standard that I believe Highbeam knows about.

 

[steve0413]

Yep, they tried metric. I took the zerk with me that broke and neither NAPA nor O'Reily could match it. The NAPA guy said he thinks Kabota might have the same as Kioti so I'll check with them tomorrow before having to drive to the nearest kioti dealer.

 

[IslandTractor]

I think Highbeam got the oddball zerk size he needed from a Kubota dealer so you are on the right track.

If this is a new machine I'd let the dealer take care of any issues if at all possible, I wouldn't mess around with a new tractor of that kind of value, or any new tractor for that matter.

The hoe should be a lot stronger than you are indicating. A full bucket of lead should be no problem for a backhoe, particularly with an 18 inch bucket on your size machine.

I'd call dealer, have them walk you through a few steps on the phone and if there is in fact an issue, they pick up, sort out and return.

Good luck,
Joel

RE: "Are these odd-ball zerks?"

Doesn't that sounds like a great insult? Like, "That guy who wears the spandex to work - what an odd-ball zerk!"

As for your problem, I had a similar sounding issue with the remaining hydraulics when one of the hydraulic lines to my backhoe was loose at the quick connect. It wasn't immediately noticeable, but it affected everything else.

Check all connections, perhaps to your front end loader, etc. If you notice anything loose, make sure you shut down the engine before pushing or twisting anything.

Make sure you post a reply as to what fixes this -

Cheers,

Jon

Great point, be very careful around hydraulics with the motor running (pump pumping), high pressure oil can mess you up.

My KB2465 backhoe must have been built in the good old USA because it's just chucked full of 1/8 pipe threaded zerks.

I remember past posts saying Rhino was the supplier for the bh in earlier years. Made in USA company.

As far as lifting power, I use a 24" bucket on my KB2375/CK30 for when I clean out my pond. I've had it heaped over with heavy wet clay and had no problem lifting the weight. Just wish I had a bit more reach. Something doesn't sound right by Steve's description.
As stated, not good practice, but I had the tractor sunk in wet clay dirt once and used the bh to lift and swing me out of the trenches. The R4 tires couldn't bite in at all. Actually had to lift the front a little with the fl bucket working like a skid and then pulled myself backwards with the bh. I just did things gently, trying to put the least load on everything. I've learned not to get stuck like this again.
