I HAVE A KUBOTA L3400 ITS ABOUT 4 YEARS OLD I BOUGHT IT NEW IT HAS A HST TRANSMISSION
WHEEN YOU GO IN REVERSE IT IS SMOOTH AND THE PEDAL PUSHES EASY
WHEN YOU GO FORWARD THE PEDAL PUSHES HARD AND IT WANTS TO JUMP WHEN IT FIRSTS STARTS AND AS LONG AS YOU DO DOT LET THE PEDAL ALL THE WAY UP IT IS SMOOTH BUT SOON AS TAKE YOUR FOOT OFF AND PUSH DOWN AGAIN IT JUMPS AGAIN.ANY CLUE AS TO WHAT IT MIGHT BE OR IS THERE ANY ADJUSTMENT.
MY BOOK DOES NOT SHOW ANY.

By chance would cruise control be engage?
Do you have grease fitting?
See if something rubbing under.

Yep the operator's manual trouble shooting section doesn't offer much.

Why are you yelling. (check your caps lock)

As to the question, I dont have a hydrostat, but on my gear tractor, I will ocassionally get a stick or something caught up in the linkage underneath and will cause the gas pedal to stick. You may want to look under the floorboard to see what may be binding you up.
