I just got a case 446 and when we looked at it drive it it moved fine fast normal. Now it will move but it has no power I can hold it while going forward and it barley pulls me. As in I can hold it and it won't move! Any suggestions on what to look into. I'm looking at the manual to see what it has to say also.

Hope we can get this figured out.

Check the Hi low range it is in front of the seat on the left side if it is on the pin that is neutral, also these require regular motor oil usually 15w 40 or something similar not hydraulic oil.

Sometimes if you put the brake on it will stick if it hasn't been used for years and there is a spring that keeps the hydrive direction selector in neutral.

might need the oil changed, my 220 I used to have had oil that would barely move the tractor, but once drained and filled with Shell Rotella T 15w40 she was very powerfull.  Mike

do u have compression in both cylinders?  might have a broken connecting rod, a Onan motor can run on only one cylinder.....or it might just be low on oil. (motor oil, used in place of hydraulic oil on Case tractors)  15W40 works good
