Backhoe BACKHOE

[DIRTCUTTER]

Is it the operator or something else when the backhoe starts to jerks.

If memory serves me correct, your backhoe is set up in a float mode, much like your loader [probably] has a float position.
I had the same thing happen to me, when i asked the mechanic he told me about the float position when i asked why you would need a float position on a BH he didn't know. He made an adjustment to get rid of the float.

I would bet the valves in the junction box are getting sticky, try spraying some lubricating lube down where the control levers go into the box. I highly doubt there is a float mode on the backhoe but you never know...

just sharing what the mechanic told me, so sorry if i gave the wrong info.

What are you doing when it starts to jerk? With digging operations a backhoe can easily "throw" the tractor around a bit and that can be disconcerting until you get used to it. When swinging a backhoe and giving it too much juice then stopping the momentum of the BH will also twist the tractor a bit and that sensation also seem very jerky. These are really normal operating characteristics. A really experienced operator will not have it happen as much but it is not really abnormal.

The BH on my 3054xs TLB (KB2376) has a boom float position on the control valve. I've not yet found a use for it, other than relieving the hydraulic pressure on the boom cylinder after you've grounded the bucket when storing

I know what you are talking about when you say throwing the tractor around, its not that. Its when I raise or lower the boom or move from side to side while the boom is still in the air. Could it be low on fuild, which I checked and it seemed ok. CK30 hst

Being low on fluid (or having air in the hydraulic system could cause an occasional "bumpiness" in the movement, but probably nothing that would even get your attention. Certainly nothing like you're describing. The air in the system will quickly be bled out as you use the hydraulics though. When you put the backhoe on for the first time, you should extend and retract all the cylinders a bunch of times and recheck the fluid level, because some of the fluid will stay in those cylinders.

Also, I don't have a Kioti, but on my Mahindra 2015, the engine RPM has alot to do with it. At higher RPMs, I have to be more careful, because jerkier movement is more pronounced. Try using less RPM

Am running at 2000 rpms very seldom going over that, I was thinking that was not enough, I just dont know

Jerkiness can also be caused by the subframe bolts, or even the
rear wheel lugs loosening up. They have to be checked often to
avoid damage.
