Some tractor options were Factory Installed (FI) while others were Dealer Installed (DI). All 200 series left the factory as manual lift and if the customer ordered one of the other lift options it was DI. Depending on the serial number range of the tractor, the 200 series utilized either a one piece or a two piece engine cradle. On either design, the engine bolted directly to the lower portion of the cradle. The upper portion for the engine cradle installed above the tractors frame but with rubber isolators mounted between the cradle and the frame. The isolators were prone to wear out over time and I think the larger (i.e., heavier) engines tended to accelerate that process.
According the the parts catalog, in addition to multiple engine cradle designs, there were also six different frames used over the 200 series production run. I am not familiar with the specific differences of each of these frames but on all of the ones I have seen the frame cutout that receives the rear isolators is somewhat semi-circular. What has me perplexed about the photo is that it looks like it may have been shot from the engine location looking backwards. If that is the case then that plate does not belong there and the isolator is totally missing.
PS. The 214H that I have does not have the rectangular plate hec posted a picture of. Could be mine is an earlier version or that the spacer was only required based on engine size. Either way, the plate shown in your picture doesn't look like strap M48772 to me.
