BX2200 problems when using FEL

[arml]

Seems this started recently. As I try to use the loader to lift anything, seems that the right rear wheel lifts, feels like it's going to roll over. Not matter if it's level ground or not. I do have ballast on the rear....what can cause this, very shaky situation.

Check your tire pressures. I'll bet that one tire is low offsetting the balance of the tractor.

 

[RCW]

Maybe one of your lift cylinders is leaking internally, and the other is trying to lift the load alone?

Maybe look at the right side lift cylinder? If left cylinder is carrying the load, pops the right rear wheel up.

Just shooting out an idea…

Maybe try raising the front wheels off the ground. See if the right side lags.

Find a flat surface (preferably concrete) that you can park on. Lower the FEL. Jump off the tractor and look at the front of the tractor. Does the bucket look level?

 

[RCW]

PS - another thought is put 100-200 pounds centered in the bucket.

Lift it just a couple inches. See if one side is lagging the other.

Thanks for all the replies, I'll followup on the inputs. Hope it gets resolved. Thanks again, I'll let you know. I'm hoping it's just OHS....(operator headspace)

By all means check out the things recommended above to rule out any tire/hydraulic issues that need to be addressed. If all that checks out and you’re still having problems, most likely whatever ballast you have on the rear is insufficient.

While I’m confident internet physics lessons could get pretty deep on the ballast issue; if your tractor is otherwise functioning correctly but the rear is coming off the ground before the loader runs out of lift capacity, the experiential evidence strongly suggest you need to add weight to the rear until the unacceptable behavior is rectified.

I would just add to what NCL4701 said, that once the weight on the front starts to lift the rear wheels, since the front axle is on a center pivot, the wheel on the light side of the weight in the bucket will lift off the ground.

This is normal. Rear wheels lifting off the ground is a sign of not having enough ballast on the rear to compensate for the load you are lifting...

Just to add one thing. I tested this by lifting a long log with my clamp on bucket forks, and no ballast on the rear of my B2910.

It was safe, because as soon as the tractor rear wheels lifted off the ground and the tractor started to tilt, the log end touched the ground and tilting stopped.

This worked on either side, depending on where I picked the log up.

So what I stated is not theory, but actually proven by an empirical test.

I really appreciate all the replies, checked all the obvious no problems found, then it dawned on me, I use a factory ballast bucket with 300lbs of sand bags in it, used that setup with no problems using original turf tires. Recently I changed over to R14 tires, great traction....however, they have a very high crown (peaked) I just wonder if this could be the cause of the problem I am encountering now...if so, then the turf tires are going back on.

 

[DustyRusty]

What is the inflation of the tires, and what is the size of the tires? It appears that they might be over-inflated. Tires should sit flat across the entire tread when they are properly inflated. On the sidewall of the tire is the max inflation for the tire.

 

[arml]

26x12.00-12 rear 20 psi, 18x8:50-8 front 22 psi 'that is the recommended spec for this new style R-14 T tire. That shape is normal for them.

About that 300 lb ballast on the back - how is your 3 point adjusted? It wouldn't take much in the way those lower link turnbuckles are adjusted to throw the ballast a few inches to one side or the other. Maybe just enough to change the center of gravity a little to the side.

I'll look at that but, I normally keep them tight.

Let me ask the stupid question: Is the loader installed with the pins fully seated on both sides and nothing is twisting when lifting?

Were the turfs loaded? How about the new tires?

I think so, but I'll look at that in the morning. Thanks for your input. You know this is a very bad situation, don't want to have a serious malfunction.

Neither are loaded.

300 lbs rear ballast is minimal for loader work on BX size tractors. Not surprising it gets light in back with a full bucket in front. Add fluid to the tires, add more weight in back, put weights on the rear wheels, etc. Also helps if the operator is a bit chubby! You want some combination adding up to more than what the bucket can carry. On my BX 2230 that was around 500 lbs.

Maybe one of your lift cylinders is leaking internally, and the other is trying to lift the load alone?

Maybe look at the right side lift cylinder? If left cylinder is carrying the load, pops the right rear wheel up.

That can not happen as the cylinders are connected in parallel. The oil pressure at both cylinders will be equal even if one of the cylinders is bypassing internally.
