I have an older b7200 with a belly mower I use for the yard. I was mowing today and stopped to move something when I put it back in gear it wouldn’t move. The high low selector moves like normal. The shifter will co in all gears and when switching from reverse to first and back it moves in the correct direction a fraction of an inch. I didn’t see anything out of the ordinary looking around the tractor and the fluid was good. Then messing with the clutch I was able to get it to crawl forward ( extremely slow) if I put all my weight on the clutch and push it as far down as it would go. Anyone ever experienced this or know where to start looking to fix it? Also the tractor is 2wd with a gear shift no hst
