X300 K46 Hyrdostatic Will it survive using a sweeper,pull cart ect...?

I was curious about the K46 Hydrostat in my new X300. I don't have any hills or slopes in my yard but noticed my transaxle gets pretty warm to the touch after a hour of use which I assume is normal considering the hydrostats have a cooling fan,I guess to keep the fluid cool?? My old Craftsman has a manual transaxle which never gets hot and I've used to pull dump carts of dirt,mulch or whatever and have for years with zero issues,I also pull my sweeper during the summer but more so in the fall.Will the X300 hold up to light loads say 50-80lbs of dirt and pulling a sweeper to get up leaves and grass clippings? Thanks a bunch!!
