I am impressed with the Husqvarna line, especially those models with the fabricated, welded deck. In fact, I plan to purchase a new GTH27V48LS with the Briggs engine. The identical model is the GTH26v54LS with a Kawasaki engine. My Gravely was powered by a 26 Horse Kawasaki, it was problem free, but fact is, they will both break down if you keep them long enough. I chose the Briggs engine simply because, parts are cheaper and readily available.
To your specific question, Google that model, you should find more data.
