I just got my Velke Pro 1 sulky mounted on my 48" Bob-Cat WB mower last Friday. I LOVE this thing!!! Lawns that used to take me 45 min to mow now take me only 30 min, with much less fatigue. Now the question...should I move the tensioner pulleys springs (that press down on the drive belts) down to the next hole down on the plate? There are 3 holes, and right now they are in the upper most hole. I thought I read somewhere that it should be moved down? Thanks in advance.
