I've been looking for a good deal on a used tractor for months now, and thought i had finally found one, but now i'm not so sure. The tractor is a 1973 3000 Ford with a gas engine. The first problem is that it doesn't have any power when placed under a load. It will sit and idle just great and throttle up good, but when you hook a finishing mower to it or just simply go up a slight hill the tractor will bog down a lot, it will barley pull a finish mower on level ground in low 3 . Could new plugs be the answer or does this sound like a bigger problem ? My second question is about the steering. When i turn the wheels to the right or left the tractor just keeps going straight while plowing up my yard with the front tires. This is at all speeds including low 1 , and is much worse when trying to turn up hill. The wheels have weights on them so i feel the front end is plenty heavy besides like i said it plows up the yard a lot. Could I possibly have bad bearings in my front wheels ? Any help will be greatly appreciated..
