BX Hood Shake

[kcender]

This has probably been discussed before but I will ask about it anyway.I used to have a BX25 and now have a BX2360 that both shake the hood quite violently when they are turned off.Do all BX tractors do this and if so,is there a way to make it better?It doesn't seem to matter if the engine is cold or hot,it still shakes.I always turn the tractor to idle for a short while before turning it off,is there a better way?Do any owners of the new 70 series have the same problem?I like the little tractor but I find this to be very annoying and somewhat embarrassing if someone is around,most people find it odd that a Kubota tractor would do this.

My BX25 does the same thing. I would say that it is simply the nature of the beast. You are smart to idle-down the engine before shutting it off. You can blow a motor if you leave the idle up--so I've been told by real big-time mechanics.

It does not change what the engine does but these little bumper can be used to keep the hood from shaking.



4shorts may have first mentioned it in is mod thread.

I tried the bumper thing.It helped somewhat but the whole front of the tractor shakes,not just the hood.I am not a mechanic but I wonder if it has something to do with the timing or maybe the way the internals of the engine are balanced.Maybe Kubota had to make it this way because of the high revs the engine is capable of.Do all BX engines do it or just the BX23 engine?

All (BX's) do the hood shake. When I first purchased my BX I thought maybe it was idling too high but a check of the manual confirmed that (if I remember correctly) around 1400 rpm is normal and recommended.

Both my BX 2200 and now my BX 25 do it. I never gave it much thought and I assume its normal.

All the BX series has the same little 3 cyl diesel, and it's the nature of the beast to shake at low rpm, such as when the engine winds down upon shut-off. It will also vibrate when idling at low rpm, again inherent to the design. Those engines are widely used in many applications besides BX tractors because they are extremely reliable. The "shut-down shake" does nothing to the longevity or performance of the engine, but you should keep the rpm's up when actually operating the BX... where the engine is much smoother and gives better hydraulic flow.

Yep, normal and nothing about which to worry.

Being a first time tractor owner, I tend to worry about every little ping or grind I hear when operating my BX. Part of it could stem from those 3 years of 0 interest payments ahead, but for the most part, I guess it's due to the fact that I'm not that handy with repairs. I did put on my Piranha bar the other day and performed my 50 hour service myself, but reading about all the technical repairs by owners on here has me wondering if I should have stuck with the "rent as needed" approach.

I have owned a BX since 2003 and if you don't loan it to a drunk uncle or someone who knows or cares nothing about equipment, the only work that needs to be done will be regular service such as oil changes etc.
