Earlier this week my across-the-road neighbor brought his JD 5425 over to move some pallets of bricks and cinder blocks that my tractor could not hope to move. (He had nothing on the rear for ballast and those pallets made even the 5425 visibly light in the rear tires, double wheel weights and all.)
Anyway, I noticed that when he turned sharply with it in 4wd the planetary gears made a fairly loud groaning sound. No popping or grinding or clicking. Just a sort of a dull roar.
Is this normal? I did not want to ask him if something was wrong. He really likes the tractor.
The reason I ask is that I'm looking for something in the 70-100 hp range and that 5425 fit the bill nicely. I have only limited experience with large tractors and no experience with JD. My tractor is a Kubota with bevel gear fronts and that is what all the larger Kubotas I've looked at have as well. I'm familiar with the strengths and weaknesses of the bevel gear set up but know nothing about JD planetary gears. Just want to make sure that if I'm test driving a JD and hear this noise that I know if it is a problem or just normal.
