My B2410 rather suddenly developed a serious transmission issue and I would appreciate any advice offered.
More often than not, when you release the HST pedal (hydro controls) traveling in Forward or Reverse, the pedal does not return to "N". At the same time I began to notice a "buck" in the steering when turning quickly. I have inspected all linkages and pivot pins and nothing is sticking. The HST pedal operates normally and is not binding or rubbing on anything. The hydro levels are all within the normal range on level ground and there is 150 hours left before the hydro fluid and filter service is due.
It seems to me like either there is not enough pressure/flow to cause the travel valves into the neutral position or the valve itself is having trouble. I have to "tap" the pedal in the opposite direction of travel to stop powered movement and that often results in a FAST and HARD stop as the tires lock and attempt to change directions.
I don't know a damned thing about HSTs except that there is no shifter lever to change gears with and it's not good for field work.
This model uses a two range HST and the results are the same in H or L, Forward and Reverse. If I knew something about how the valves were constructed or what could cause this type of situation, I could fix it (as a certified diesel mechanic with 25 yrs experience).
