My 07 700 is having issues with the clutch or the transmission locking up. It seems like I have a brake stuck on and I really need to give it throttle to get it to move. When I put it into neutral I can push it with no issues.....just when I am trying to drive it forward or reverse it has this major resistance. I am thinking something in the clutch or transmission is binding up or a bearing starting to lock up...just a lot of resistance. There is also a lot of howling noise coming from the clutch case when I get it to move. I have been using it for pulling a large drag on the farm this spring and it started after that. I will be tearing off the clutch cover to see if anything in there doesn't look right.
