I noticed today that the front wheels were not pulling real well. The rear tires would spin when bogged down by the implement but the front ones would not. I raised the front end with the loader and the do spin they just do not have much power when on the ground. In the past the front would spin also. I checked the parts manual and it only looks like a driveshaft and gear set up front. Is there any easy way to check this before I start pulling apart the differential? I am going to have to get the tractor to my garage to work on it and it is still out at my place.
