We rented a 500 bu. manure spreader and hooked it up behind the 18 this weekend. Was a heck of a load for it (Kuhn/Knight reccomends 120 HP minimum, 1855 dynoed at 105)
It's got a hydraulic apron, so I plumbed in a coupler at the bottom of the reservoir next to the bracket for the top link and had the return going in there instead of through the remote to help keep the oil cool. Must have worked, as after unloading I couls still hold onto the hoses for the apron control.
I hauled out 17 loads, which would have been about 40 with our spreader. The front end got a little light for steering, even with the starter, 1 stack and 4 slabs on the front. Sure made the job go fast though.
