I am looking to buy an Exmark HP or Lazer and trying to make a smart purchase. I am a part timer and cut residentials (small & large). I looked at both today. The HP does not have but 3 anti scalp rollers which are all in the front. My Turf Tracer HP has 4 but none in the back. It never really scalps but if it's wheel dip into a hole, the back of the deck can get into the ground without the rollers. Is this a problem with the HP since it has no rollers in the back? The Lazers have them all around. Also, do you like your HP?
