Inherited a kubota rtv900 from the wifes grandparents that had been sitting for a few years. It was parked because it had started struggling in h and m, seemed to drive better in l. It still cranks and runs fine but definitely loses it's power in H. I had to jack up the rear end to work on the tires and noticed that the back right tire doesn't spin in Neutral, the left wheel does easily. Am I assuming correct that all 4 should push/roll easy in neutral? Is that what is causing the loss of power in h and m? If that is the problem, are the brakes locked up on that side or what? Thanks for your help!
