This is an Ariens S-14H. Has a K341(16HP) in it now, originally had a K321(14HP)---It will eventually go back in the tractor after being rebuilt. The tractor has a Sundstrand hydrostatic transmission. Front and mid PTO's shafts are driven by an electric clutch off of the end of the crankshaft. The rear PTO is a constant run shaft off of the transmission. The attachments are raised and lowered by the hydraulics. I use this tractor for tilling the garden and moving dirt with the blade.
