I picked up my new metro hp today and tested it out on my lawn and adjusted the brakes a little but every thing seems to be all or none do you have any answers for this so I can pull back on one side while the other spins and to let one side spin a little slower while the is full on (like to go around a big tree). And my first complaint is that when I put it in fifth gear the shift lever hits the drive control linkage when drive is engaged and seems to be a big problem. I don't know how the engineers let that one go. Thanks for any and all the help. Also I have the 36"
