My Wheel Horse came with an Ark Loader
I think its an Ark 550 ? - The manual has Model # 07-72FL01 for the loader frame and 07-48BK01 for the 48" bucket.
It has a 600 lb capacity, Dump bucket to full dump is 5 seconds, Raise bucket to full height is 6 seconds. Runs on a front PTO Mounted 1000 PSI Cessna hydraulic pump. ( according to the manual)
Oil capacity is 6 Qts 10W30 oil ( I run synthetic 5W30 - it works better in the cold)
This loader has a float feature - One feature I did not know about was that while in float, if you angle the bucket down, it adds down pressure to the float. This is very handy for leveling and digging !
I have a dozer blade which mounts in place of the bucket - I'll try to get some photos up soon.
I added a return line filter from Northern. ( says FPC - Fluid Power Corporation on it ) 3/4" npt inlet - you need use 3/4" to 1/2" reducers on both ends
The hydraulic pump coupler disc went bad recently - I replaced it with a double disc made out of two snapper steering ? discs. I held them together and drilled holes through them - they were around $ 3 each - still works fine after a year's heavy use
