When I bought my BX25 2 years ago I asked the dealer about filling the tires. He stated as long as the tractor was in warranty he would not do it and if I had it done elsewhere it would void the drive train and engine warranty. He said the reason is on the 25 the tire side walls were too weak to withstand the extra pressure especially with the BH or a heavy implement attached. I discussed with my local Schwab tire dealer and thay do it all the time on SCUTS. They have a Yanmar dealer down the block and they fill their SCUTS before selling. They have tires similar to the BX. I am on the fence. I need to lower my COG as I am now working on hilly terrain a lot. Wheel weights sound like a PIA and suitcase weights are very expensive and you never see them used. I may just resort to making hang on concrete weights of various weights. I would make brackets so they hang as low as possible. I will be watching this thread to solidify what action I will take.

Pound for pound, water ballast puts less strain on the power train than wheel weights. As for more power to turn a wheel with water than wheel weights, think of it this way, how much power does it take for water to run down hill.(think how much friction does water have on the tire) For sure there is some friction of the water to the tire to overcome but that would almost be impossible to measure it would be so small. The water would put more weight lower to the ground also. As for not filling the tires with a backhoe, I can only think of one reason and that would be the extra weight put on the tires and stabilizers trying to lift it, HOWEVER, the BX tires are so small that it wouldnt be adding any appreciable amount of weight for the hydraulics.When I bought my BX25 2 years ago I asked the dealer about filling the tires.

Another classic case of misinformed understanding of forces. Tell me - why does the kubota manual says NOTHING about having filled rears when using the 3 pt to the max like a bush hog lifted up or any implement? Wouldn't this exert the EXACT same forces but more perhaps on the sidewall tires?
Come on guys -- like I said before, something is not kosher with that statement on the manual.
Unless their concern is the weight hanging off the axle when the stabilizers pick the rear of the machine off the ground...

I "hope" it is just a tire issue. Here is a novel idea, how about a letter asking why
to Kubota Inc?
