New to skid loaders. Just picked up a lower hour 6675 for a really good price. The machine lifts and titls effortlessly and also goes forward and reverse with no problems at low idle or high. But when tring to make a turn it seems to growl and chatter really badly and struggles turning. under low idle it will almost stall the engine high idle just makes the noise louder. Like i said im new to this but do alot of automotive mechanical work and also work as a maitenence tech for my job. Just not sure where to begin. The previous owner also used tractor hydralic oil in the hydralic system, but looking at the servic manual it says 10-30 . any ideas ? its the same machine as a lx665
