Does anyone have their rear tires loaded? The manual says it may be necessary to load them for stability when the backhoe is not attached but that they should not be loaded when using the backhoe. I never plan on removing the hoe in fact I don't even have the 3point arms. The machine seems light and easy to push around when digging. Seems that filling up the rears would help a lot. I can't figure out why the manual says not to fill the rears when using the hoe. I figure the tires will hold about 500lb each. Surely the outriggers can lift up an extra 1000lb?
I am a big fan of weight on tractors. Everything I have owned prior to this has had loaded tires and add on cast weights.
" I can't figure out why the manual says not to fill the rears when using the hoe."
Well, my guess is that nailing down the tractor with that much weight would cause too much stress on the hoe itself. As it is, Kubota has already given us more backhoe than the tractor's normal weight can hold steady, and I'm figuring that letting the hoe move the tractor around is a "safety valve" for stress on the BH and frame components. If you've ever looked at that main swing pivot platform on the
M59 BH and then taken a gander at the same part on a full size TLB....well, that darn plate on the
M59 sure isn't all that beefy. Of course it does work OK....and I've never heard of one breaking or bending....but there has to be a limit somewhere and tractor weight just might be where the limit lives.
But maybe there's still room for you to add some weight....because it just might be that when the Kubota engineer wrote that part of the ops manual he was assuming that the owner already had the full allowable complement of three factory wheel weights per side and are meaning to say not to add loaded tires to the wheel weights that are already there. Could be.... after all, wheel weights really are a better solution even if more expensive, and the guy is probably some sort of engineer so he's got little concept of money or the real world outside anyway....
....so maybe he just figured anyone with an
M59 would go with wheel weights first.
Can't help much more than that. Weight isn't a problem where we are here in Colorado. Just as it comes stock is good for us here in the Rocky Mountains where what we want is light weight coupled to high muscle. The
M59 sure has both those things... just as long as we can agree that weighing something over 4 tons is to be considered "light".
Whatever you try, good luck and let us know.
luck,
