I used my tractor and Caster on Tuesday. 446 with a P218 transplant. I had to nibble at the wet snow, kind of pissed me off. I got out the 224 with the 54 inch blade and pushed a little, it did NOT like that heavy snow. Back on the 446 and had to baby the snow. Went to the garage and checked the clutch adjustment, all OK there. Still stopped the snow caster in a full head on bite of the wet stuff. Worked it slow and steady and cleared the main portion of the drive. Today went into town and stopped at TSC. Got a 5/8 wide belt to put on the front clutch/PTO drive and WOW what a beast again. I cleaned the rest of the drive and even cleaned up all the piles where the 224 had pushed in into a wall. I believe this is the first time I have ever heard the Gov kick in on the 446. It stopped for nothing, to the point of almost stalling the engine, and absolutely NO slippage.
