I have a 25ft 994? honey bee front on a new holland hw340 swather and problem is it's running WAY to fast!! Can't get over 1380 rpm or the reel and belts are going off its **** on the verge of breaking something, usually run it at 1800/1900 rpm for this machine. Machine is set on sickle cutter mode but is it possible it's not changing pump setting still? Also I've had both decks out and reel off so it would of got air in the system while hoses were off so would air in the line affect it? Any help?? Thanks

Not sure on that modern stuff but the old jd was surging and had a lack of speed control up untill I rebuilt the speed control valve and found a piece of oring (I suspect) in the valve. like new now
