B2320 HST pedal sticking

[gyro433]

Hello everyone,

I have been using my B2320 HST for 2 years now and I am mostly completely satisfied with it except for the HST pedal sticking. I am wondering if others have had the same problem and found a solution. The problem occurs when I use the tractor in forward or in reverse. If I push the HST pedal fully for an extended period of time ,(10 seconds or more) the pedal does not return to neutral right away, there is a small delay 1 to 2 seconds as if the pedal is stuck. You release your foot off the pedal and nothing happens for about 2 seconds and all of a suddenly the pedal returns to neutral and the tractor stops abruptly. As you can imagine if you are maneuvering in tight areas it does not work very well and this can be a safety issue.

I lubricate the zerk on the pedal regularly. The funny thing is if I push forward or reverse fully for a short time, the pedal comes back to neutral immediately. If I push on it back and forth in neutral, the pedal returns to neutral immediately which makes me assume that lubrication is not the issue. The problem seems to get worse when the temperature gets colder. It also does not change if the tractor is warmed up or not.

Is there anybody else with the same issue ? I am wondering if there is some other adjustment to be made.

Thanks in advance for the inputs

I just had an issue with my B3300SU (90hrs) the dealer came out and fixed. Question? What type of grease are you using?
My issue, won't start (can't hit the sweet spot on HST) The problem was with the plunger,(saftey devise) dealer took off, sanded, anti-siz applied, no issue. Also check your spring, WD40 or some penetrating oil, re-grease.

Dmiele, thanks for the reply.

I am using Valvoline Cerulean grease NLGI No. 2, it is a heavy duty grease application for industrial and agricultural equipment.

I have check the spring but mine is covered by a plastic cover, so unless I take the cover off I can not reach it. The pedal returns to neutral fine with tractor not moving with engine on or off. It also woks fine if you push on it for a short period. I suspect something has to be adjusted inside the linkage. I found a video on you tube about the same issue. Here is the link.

Yup, my 2920 does that to, I thought it was because it was getting cold out or the oil was cool. Mine is find when it gets warmed up, so far this is my first year with it.

Crow,

Mine did the same the first year, when it got warmed, the problem seemed to go away. This year the problem seems to stay. I used the tractor 2 hours today with an outside temperature of 50 deg F / 10 deg C and it did it for the 2 hours. I am more worried for this winter as I am using my rear snowblower a lot and if the tractor does not stop when it is supposed to then you start hitting stuff and damaging equipment.

Did about 3 hours of work yesterday and outside temperature was warmer than he day before by a few degrees. Tractor pedal operated normally. I will keep investigating. Will talk to my dealer maybe at the end of the week.
