Loud bang noise on start and stop of New Bx2380

[Henro]

Good looking wood, highly figured for ash.

This is ash from a standing dead tree on my property that I -Properly felled- (dropped on target and nothing damaged):laughing:. I kind of regret using it for these cabinets as the house will probably end up being rented. But at 60 cents a board foot (cut and kiln dried) it was very cost effective. Interesting grain patterns...

Hi All,
This week I had my second purchased new Kubota tractor delivered this week. A Bx2380. So far so good other than I have noticed a large start and stop bang noise. I'd like to know if anyone has noticed any loud bang noise on starting and stopping a Bx? I suspect the torque on the starter motor is doing this on start and the torque and weight of the Diesel does it on stopping. I have not really looked to hard yet on why the bang noise is so loud. Once started, the engine purrs. I warm the engine prior to starting for about 20 seconds.
It looks like the motor rocks back and forth when it starts and stops. Is this normal? Maybe the motor mounts are not stiff enough or tight? Not sure - like I said, I have not really dug deeper nor used the tractor much other than cutting some grass to check out the 60inch deck. My B2650, which I have had for almost 7 years now and over 1000 hours on it now, does not do this. It makes a little bang on start. Nothing as loud as the Bx. I will post a Video of the engine while starting and stopping tomorrow. I'd appreciate any comments you all might have.. Thanks ! Oh - Here's a pic of my tractors in front of the Woman's She- Shed View attachment 654427

It's the brackets on the engine that are hitting the frame. I doubt the mounts are bad. Mine did it and I placed vibration isolation between the frame and the engine piece. Bad design. I also think the mounts need stiffer rubber.
