backhoe question

[diaedy]

Got a new ck35 with a kb2485 hoe an frame. This is 1 size bigger than normal but dealer said would work fine as it weighs only 35 ils. more than 2475. My question is when putting down outriggers they do not lift rear tires off ground. Is this normal or are cylinder too short???
Thanks

Hi, i have a KB2475 on my CK30 and the outriggers don't lift the rear tires off the ground. I have bigfoot pads on the outriggers, this is a must. To lift the tires off the ground i lift the tractor with the boom then set the outriggers down. Hope this helps.

I have the older model KB2375 on my CK30hst and the outriggers will lift the tires off the ground. When I first bought the bh, I thought that was how you set it up just like the bigger dedicated loader/bh machines. After some reading, Kioti suggests lowering the bucket on the ground to stabilyze the front, setting the brake on the tractor and not lifting the tires but use the outriggers to stabilyze the rear. This has always worked well for me.

+10 Do NOT lift tires off the ground or you will run in danger of splitting your tractor.

If you put the bucket down to the ground and then try to lift the tractor with the backhoe outriggers, you are lifting the whole weight of the tractor on the bucket and the two outriggers, none of the tires would be on the ground. Not good as Murphy says.

As others have said, don't lift your tires off the ground. However, you should be able to do so. If you cannot on level ground, something doesn't sound right to me.

Thats exactally what I was thinking.

I want to thank everyone for the reply's but I can't get it in my head as to why The outriggers won't lift tires. it's like they are to short. Dealer says to put 3 ---4 inch angle iron plates on the pads about 8 inches and one the opposite way to stabilize but I guess I'm old school. I'm afraid hoe may be too big for ck35???????

 

[LD1]

I would think the bigger hoe would have longer outriggers???

Maybe it just doesnt have the force to lift your tractor. Are your tires loaded???


Have you tried lifting the rear of the tractor with the hoe itself? To see if the outriggers really are out of travel, or just lacking force? Or try some blocks of wood under a pad?

I agree that it isnt good practice to lift the rear, but you at least need to be able to for when working on uneven ground and you need to level up

 

[murphy1244]

I have the same Hoe and I can lift my loaded tires off the ground a good 4 inches at least. How does he have your hoe hooked up?

if the outriggers arent lifting tires off the ground the tractor will be pulled back more easily lifting the tires off the ground will split the mach in two? first of all a case backhoe there is no frame like on a tractor the tranny is part of the support and when you lifted the tires off the ground which you allows did the mach didnt split in two lol grewup on one

who is talking about case?

 

[n4msl]

Very strange indeed. My 2485 won't even think about lifting the unloaded tires on the DK40.

 

[Gil Case]

One more time, is the bucket down??? If so you are trying to lift the entire tractor- the outriggers will not do that. Put the bucket up and you are only lifting the rear tires, it should do that.

There is definetly something wrong if the stabilizers wont lift the tractor. If you cant lift one side, how can you level the machine when digging. Most of my digging with my B26 TLB is on unlevel ground so when I set the stabilizers, I put the one down on the high side first and firmly plate it taking all the weight off the axles, then I lift the low side till it is level. When I do that the low tire may be 4-6" off the ground.

links to specs between what is normally placed on, and the size bigger that you have?

==============
with this being new as well. there is a good chance "air" is still within the hyd lines and cylinders. and you have not been keeping an eye on the hyd tank. to make sure it is kept full. other words dealer just installed. backhoe. filled up some hyd oil but never operated the backhoe and the stabilizers to work out the air. and if they did, they did not keep an eye on the hyd tank to keep it full as the air was purged.

are relief valves kicking in? or engine bogging down at lower idle? when you try to put stabilizers down.

double check that you have hyd hoses going to correct levers / hyd valves on backhoe/stabilizers as well.

i generally do not lift tires off ground. but will slightly take pressure off of tires. and/or raise one side to help level the rear end of the tractor. but the stabilizers should be able to lift rear end of tractor. not sure why anyone would build a backhoe were a stabilizer could not lift rear end of tractor. they are a important part of use of a backhoe.

 

[boggen]

quick note: going to a larger backhoe. means backhoe will more likely move more slowly. vs a smaller backhoe. (cylinder diameter sizes) on larger backhoe. will require more hyd oil to be pushed into them. on a larger tractor were GPM would be higher it would be no big deal. but on a smaller tractor were GPM is more likely not as much. the backhoe will move slower.

be careful with larger backhoe vs smaller size backhoe. the larger backhoe could put extra force on your tractor. what you might get away with smaller backhoe. may mean bending or breaking something with a larger backhoe. if the larger backhoe is not spec'ed / warranty for your tractor. example larger backhoe being able to lift more weight. and putting extra stress on rear end / tires / axles on tractor if stabilizers are not down.

My question is when putting down outriggers they do
not lift rear tires off ground. Is this normal or are cylinder too short???

As others have said, not normal, no.

The 2485 weighs 1102#, and is supposed to come with its relief set to 2466psi. Your
tractor puts out 2560psi. Check your pressures. I have seen new hoes with RVs
set 1000psi too high or 1000psi too low.

Admittedly, my hoe weighs more than the 2485, but it's outriggers can lift the
tractor no problem, even with the FEL bkt down. And that's with a CK30.

It is interesting that the 2485 is only slightly bigger than the 2475, digging only
4.5" deeper.

 

[Gil Case]

but it's outriggers can lift the
tractor no problem, even with the FEL bkt down.

Does this mean that the outriggers are lifting all four wheels off the ground so the tractor is suspended by the the two outriggers and the bucket? All four wheel spinning?
