Let's get the facts straight! What are ALL the differences between a Lazer HP and a regular Lazer? I am talking about ALL the differences. And what are the pro's and con's of each of the differences? Why do I ask? Cuz I'm curious! Thanx in advance!!! Here are some of the differences that an exmark representative has told me in a e-mail, but even he said there are more: The biggest difference in design is that the HP is smaller. The full size uses what we would call a tubular rear frame, were as the HP is all formed steal rear frame. The pumps and engine are mounted horizontally an the full size, HP they are mounted vertically. Full size Lazer uses a serpentine belt for the pump drive, HP uses an A section pump drive belt. The big Lazer uses a mule drive system to run the deck, the small Lazer uses a single-plane drive belt. The big Lazer can cut from 1.5" to 5", the HP 1.5" to 4.5". The full size Lazer has a total of 3 belts and the HP has 2. Plus the Lazer has bigger tires than the HP. Now what would you say the pro's and con's are of the differences aleady mentioned? And what other differences do you know of?
