low gear(hst) 2600rpm's /bucket/boxscraper/ when climbing slight incline and making a hard turn the tractor nearly stalls. When going straight /side of hill/ no problem. Seems only when climbing, is this normal for this tractor or should it move with authority. Had previous 2400 and it bogged down , but the 3130 bogs even more? Dealer changed fuel filter/ wants to dyno check HP? If this is the new Kubota, then what a disappointment!
