Yes or bad motor mounts, bent driveshaft. Any number of things. Try running it with drive shaft off. If motor is moving around a lot its probably mounts if engine sounds normal and is running smoothly.

Had that happen on my 716H one year plowin' snow. Started feeling a vibration that wasn't there before. Immediately went down under to check things out. Eventually found the bolts had loosened on the front yoke and it started egg shaping out the fiber disc in there. Had some spare parts from another 716H I had and used one of the discs from that. Problem solved. Made sure I checked those yokes on occasions for tightness...
