B2920 vibration under load....

Does the vibration sound sorta like a ratcheting noise? What gear were you in? My hst makes a kinda ratcheting sound when under load. Like when I first take off in a high gear or start to go up a steep hill. I would call it a slow ratchet and it is directly related to the movement of the hst pedal. I beleive that it is not right on mine, but have not come to any conclusions. I am guessing/hoping it is a relieve valve or something.

Funny but I too can say mine emulates a lot of different noises. What I am compare it to is my old BX22 - that thing just turned over and made all the right sounds no matter what I threw at it - now with a different platform (B2920) I am getting sounds / feeling I am not used to yet - it maybe me but the "vibration and vibration sound" I experienced with the middle buster plow 12 inches deep while I was in 4 wheel drive (2000 rpm) just did not sound and feel right.

Just now however it occurs to me that (and I am embarrassed to say this) I do not recall what "speed" I was in

? Most of the time I am in Medium and never seem to need to go to high and very rarely low but with only 10 hours on the clock my gut is telling me I was in Medium when I was plowing.......if that was the case do you think being in medium under load could induce this phenomena. More to try when I have a minute.

I'll let you all know what I find out.

Mine does do this too.

I do use low range on mine quite a bit, and did use it when I was using my middlebuster this spring. HST transmissions do have relief valves, and such, and could be generating noises, vibrations, etc. when not used in the proper range for the job. I wasn't sure what was under my ground so I went slow, and easy in low range, two wheel drive, using wheel slippage as the weak link.
