This may or may not be your problem....check the fork and lever attached to the hydro. At the hydro end of the control cable is a steel fork which moves the lever attached to the hydro. Both the lever and the fork wear with time and need to be rebuilt or replaced. This usually causes a decrease in speed over time so I'm not to sure about your issue. This would explain why reverse is still good because the reverse side of the fork and lever don't see the the same use.. let know what you find. I will also mention that my experience is many with the 1600's but i believe the 14 is the same
14 Series Hydrostat Question
Hey all... 1420 without a mudhog... suddenly this year comes out of the toolshed with lack of ground speed... I usually run between 4 and 4.3 MPH in corn depending on how my rotor sounds like it is handling it... Suddenly without the seperator even engaged and on level ground, I can only get 3.8 MPH out of it in second. Road gear also slow... Reverse a little sluggish, but seems much better than forward gears... fluid levels all good, please tell me hydro is not failing.... even though it is slow, it still pulls the hill coming up onto the road like a champ, maybe a slight loss but not like a hydrostat going out... Can anyone offer any theories or ways to check? We were half an hour away from being ready to go today (would run as fast as we were going to cut beans anyhow), and then we got two inches of rain about 8 hours earlier than forecast.
