Backhoe Backhoe for 3050HSTC

[5030]

Is it possible to mount an aftermarket backhoe to a 3050 with a factory cab? Kubota hoe's will not fit and are not recommended. The tractor has a subframe for the loader. Does anyone know what fits? This is my 5th Kubota and 1st. cab model. I'm getting old and I like the comfort, especially when blowing snow. This new hydro has gobs of power, I just hope that it will operate my 13' J.D. Mo-Co this summer. I'm sure it will run my N.H. 650 Round Baler, however.

Is that an L3050 or an L5030 that you have? Sounds like a 5030.

You are right, but I still need a backhoe. See what happens when you get old like me. I do know it's a KUBOTA, however.

I guess my problem is that I'm trying to make it a Deere, I also have a 4020.

Too many numbers for me.

Hi, 3050... glad to hear you are enjoying your new rig. I'm not any expert, but from reading earlier discussions, here are a couple of things people have encountered with the Kubota Grand L cab models of the previous generation.
1. Backhoe's would not fit because the operator's position was basically in the same place as the back window of the cab. I don't know if one of the hoe mfr's has a unit that gets around this problem.
2. The cab adds weight (~500 lbs?) that limits other choices. With the 4610 Cab, for example, you could not ballast the rear tires because the cab + ballast weight exceeded Kubota's conservative rear axle limit. A backhoe is quite heavy, and I don't know if it causes a similar weight problem with a cab, or if the new 50 hp tractor you have has been upsized to handle it.
A knowledgeable dealer should be able to give you the straight skinny about this. Good luck... I am likewise backhoe shopping for my non-cab 4610.

Hey 3050,
Congrats on that tractor. I recently got the 3430 HSTC and I love it. I am glad somebody finally asked about the model number, I couldn't for the life of me remember any 3050. Anyway, in early Feb or Jan of this year there was a post on this very topic. Bradco & Woods would be the ones to call because they were looking at making a backhoe for the new Grand L30 series with cabs. Can't find my notes or the saved link to this thread but I hope this helps anyway.

Here is a picture of it, just washed and getting put to bed.

Does it actually tell you not to ballast the tires if you have a cab? Ballasting the tires increases the tractor weight, but does not directly impart that weight to the axle. A boxscraper at 1200lbs and buried into a pile with a 3pt hitch lift of 2760lbs certainly far exceeds any weight ballasting could add. Likewise a much smaller yet still stout front axle will receive loads far in excess of that with a full load with a leverage or moment that amplifys this tremendously not to mention the additional jarring. I can't imagine a cab adding squat. The BH 90 weighs in around 2000lbs. Again dwarfing the weight of a cab. I would find it interesting that they recommend against ballasting a cab model.

RaT,

I'm curious about this too. The book for my BX22 says to remove ballast from rear tires while using the backhoe. The backhoe weighs less than what the 3ph is rated for at the lift point, and a good bit of the BH weight is carried closer to the tractor than that. And yet, it does not say "if you have more than X lbs on the 3pt, remove ballast from tires". I guess I don't understand why the BH requires removing the ballast, but other loads don't. Nor do I understand why the cab would be any different than an implement hanging off the back.

I think that the recommendation is relative to the rear axel weight limits of the BX, similar to what was eluded to in another post above. You have close to 6500 lbs in the BH, itself, and although it's not directly on the 3ph, it still adds to the weight of the tractor.

Well, I had it right - he said, sheepishly - no ballast in the tires of Kubota Grand L10 factory cab tractors (Page 57 of owner's manual) - but for the wrong reason. You're obviously right, RaT, about the weights of implements, etc... that had me scratching my head. But, according to a thread last year on the subject, the reason for the restriction is that the built-in ROPS in the Kubota cabs has apparently not been engineered to support the weight of ballasted tires in a roll-over. Again, don't know if new L30 series is the same.
