Hi all . I'm new to the forum ,but have a question for those who know. I recently took a B6200 hydro 4wd on trade. It came with a very nice King Kutter 60 inch rear finish mower. I have very little experience with compact tractors. The B starts fine runs fine and sounds good.I hooked the finish mower up and tried it out .The tractor mows ok on level ground but on any incline it will barely pull its self with the pto engaged. I realize this is small tractor but I see them listed with 60 inch mmms. I will sell the tractor and mower separately but I'm wondering if this unit has a power problem .It doesn't smoke blue or black under the load. I just dont want to sell it to someone if it's not right. I know this is a long rant, but I would really appreciate any input . Thanks
