I have a 1974 H3 that has been in the family since new! I've had a tiller, snow blower, and mower deck that I use yearly. I just purchased a 4-way plow for it. Problem is I can get it to go up and down with no problem, but not left to right at all. I have a cylinder lockout link for the rocket shaft cylinder, but still nothing. I have switched hoses to other side to check the plow cylinders and both work fine on the one side, but not the other. I'm at a loss as everything else works as it should. Any help would be appreciated. Thanks!
