Do you have a question about the 4520K and is the answer not in the manual?
Questions and answers
What is the pivot height off the ground of the hitch point on a Ventrac 4520 tractor. I'm going to attach the EC240 24" sod cutter to a different tractor and I'm thinking the pivot point is critical to maintain so the sod cutter will function properly. I went to Burris Equipment in Waukegan, IL and measured that pivot point to be around 10" but the tractor was sitting on gravel so I'm wondering if 10" is correct or is it a 1/4" or 1/2" higher or lower. Thanks for you help. Dan Cline 1623 N Wilke Road Arlington Heights, IL 847-392-6630
