in mud I find using the manual engine speed set to high works well.This gives you the needed rpms for the engine and you can increase or decrease the transmission speed with the foot pedal.Ive found this works in mud and deep snow.Personally id like to see it spin tires when needed but i just dont like the way the HST is set up.I would love to see one of these set up with a clutch vs HST.
Good points Mark. I thought about discussing the hand throttle option. But since he's not equipped with one I wanted to discuss his current options and expected results.
I ordered a Hand Throttle kit for mine last week. I see it being very helpful in these types of situations.
Since discussion on this forum is limited to RTVs I am unsure when talking to someone if they have experience with HST in tractors? I believe that an operator that does have previous HST experience in tractors can better understand and compensate for the HST system's limitations and weaknesses.
When trying to get thru a difficult situation and the engine begins to bog down, it's very hard to convince yourself that letting up on the pedal will gain engine torque and power. That just doesn't make sense.
With a Hand Throttle holding the engine rpm at a preset level of your choice, then using the foot pedal to only control HST speed it should be easier to control and get the most out of the system.
But in the end, if the obstacle at hand is plowing thru long runs of deep mud the RTV is not the best choice of vehicles.
