I received a Cub Cadet 1600 from my neighbor for free. A low end mower for sure, but the price is right. I am having a problem removing the left rear wheel. I used P-blaster, heated the hub, drilled two holes along the shaft into the hub on each flat and squirted P- blaster in the holes, beat the wrench on the wheel puller with a light hammer, and it will not budge. The right wheel came off with no problem. I do not want to hit the puller wrench any harder lest I damage the axle bearings. I thought maybe a hydraulic puller?
