Hi Gary,
Welcome to the forum! I have an Iseki that is 30 years old, and it runs great, and it is a tank. Iseki built and builds very strong and durable tractors, and it should last you for years, and do everything you ask it to as long as it is in decent shape. Mine is only a 15hp and I have more than enough power to use a middle buster, to run a full sized post hole digger, run a 3 point wood splitter,plus many other uses. The pto's are usually three speeds, with the lowest just below 500 rpm. They work great for all of the implements that are designed for the standard pto speed. You just shouldn't run some implements like a brush hog in the high gear. The only other real difference is if the tractor is the blue version, the throttle is pulled backwards to increase rpm, the opposite from most western machines, but you cannot beat the Japanese craftsmanship in these machines. the we're built to run rotovators in a foot of water and mud, so the are sealed very well, and very well built. Let us know if you get it,
