Brand new to tractor world. Dealer set up my MX5 rotary cutter but I think it's too low. Reading the "Adjust Cut Height and Tailwheel Position" portion of the on-line manual I came to the section that says the center link should be adjusted "to take all slack out of the connection." It then it indicates a measurement of 1/2 inch but I can't tell from the drawing where that is to be measured. I suspect mine may be wrong because the manual also says lengthening the center link to that 1/2 inch spec will "allow the cutter to float over obstructions." The ground I mowed was rough and there wasn't much "floating" going on. I assume it's relevant that I have a Top and Tilt kit. Suggestions welcome. Thanks!
