I've had the 1455 Power Shuttle on the lot and now have a 2WD & 4WD 1455V. I love the 1455 power shuttle but looking at it from a consumer prospective, it is a little pricey. However, if you have a need for the power shuttle then it is worth the money. But, if you are looking for a simple, standard shuttle transmission, look at the 1455V. It is priced right and it is a great looking machine. As for the weight issue, the 1455V comes in just under the weight of the 231S. It does have the weight to match the 55 HP hidden underneath the compact exterior. I think that Massey has done a great job with this line in attemting to fill the void left by the 243 tractor. The 1455 is not the same as a PERKINS WORKHORSE, but you'll be hard pressed to find a better, well priced tractor on the market. Hope that helps.
