I'm not sure if this is a symptom of wear or if it is to be expected. I cannot climb a moderate grade in high range with any significant 3-pt load such as a rotary cutter. It is in transport where I notice the slippage of the HST. The implement is elevated at this time. No problem operating in low range pulling a disc, box blade or spring tine harrow. I'm just wondering if it is a sign of things to come which may get worse or if I'm asking too much of the HST??
