debating between turf-vent 40" and the turf-aire 36" for my 318 john deere. i will need to purchase and mount the 3 point yet, i feel 3 point is the way to go vs. pull behind. i measured the width of the jd and it was 41" across the back tires. i'd like to stay within this so if i take off the mower deck i can fit inside the 4 foot gates. the turf-vent is $600 the turf-aire is $450 i'm not sure what shipping is yet but i'm sure the turf-aire is a lot to ship because it's 360lbs. which would you go with?
