Both the Bolens and he Cub Cadets are well built.While parts for the Cub Cadet are easier to find right away you can still find a ton of Bolens parts when you look around a little bit. I own a few Bolens' like a 1050 and a 850 and also two Cub Cadets, a 147 and a 104. Personally I feel the Bolens tractors are easier to work, specificly the driveshaft area. On a Bolens you still have to crawl under the tractor some but most of it can also be accessable from the top of the tractor too. Compared to a narrow frame Cub Cadet in which you can only access most of the driveshaft area from the underside of the tractor. Also as Ed-nh said the engines are also easier to work on. For example if you wanted to remove the engine form each you can easily have the Bolens engine out in 10 minutes compared to a Cub cadet in which there is a lot more stuff to work around.
