Loaded tires with backhoe attached...

[Talionstallion21]

Who unloads their tires when they put their backhoe on? Was reading my bx25d manual and it said to unload rears when attaching and using the hoe. Do all of you do that? Is it really bad if you don't? My dealer is 50 minutes away and I don't have a trailer so it would be spendy for them to come here twice a year. What say you?

I don't unload the rears on my B2620 for backhoe operation. Frankly just don't want the hassle and expense. I don't know the repercussions though, so I'll be interested in others opinions.

What are the repercussions?

May want extra set unloaded rear tires considering dealer pickup delivery plus service charge for the future.

Any chance there's a misprint or maybe a 翻訳 problem?
Maybe they mean to lift the rears off the ground, rather than emptying the tires of ballast?
That's standard operating procedure to get the support on the wide set, rigid stabilizer pads and off of the narrow, flexible tires. Maybe the stabilizers can't lift the rears with the added weight of the ballast?

If given the option, I'd want ballast in the rears with the hoe on, for increased lateral stability.
Even with the rears in the air, it's weight that lowers the CG, making slewing with an extended boom & heavy load less likely to cause the tractor to tip.

I'm curious about the reasoning, if that's really what is recommended.

Page 55 of my owners manual says "while bt602 backhoe is installed on the tractor liquid ballast in the rear tires should be removed".

Yeah, I've seen this discussed here before, but I don't recall anybody coming up with a good explanation.

 

[GolfAddict]

Yes, it has come up on occasion, and I've never seen a good explanation either. I can say that, even though my BX24 has the same in the manual, I've ignored it as it just doesn't make sense to me. At almost 1000 hours, it's never caused any issues.

I have to say, I don't use the BH that often, just a few times a year. But when I do it is for hours at a time.

Not sure why the loaded tires should not be used with a bh . Maybe it has to do with the stabs having to lift the tires? My 2620 has no problems lifting the tires that are filled with calcium. Oh well, no problems so far.

The Deere 448 backhoe manual doesn't state anything (that I could find) about removing any liquid ballast from the rear tires. It also indicates (and shows in pictures) the rear tires should be just off the ground and the rear supported by the stabilizers, when operating the backhoe.

It's possible the backhoe, along with ballast in the rear tires, may overload the rear axle. If any of you find out why Kubota states "no ballast", I'd like to know just out of curiosity.
