I have a 60 inch mid mower on a B7300. Been thinking of gearing it down, putting on dethatching blades, and using it to shave off the many bumpy spots I have on my 10 acres. The ground is so bumpy, if I could smooth it out some, I could knock 1/3 to 1/2 of my mowing time off. I thought I'd need to gear it down or it will just tear everything up. Anybody try that, or have another idea on leveling that much area? Thought about a Harley power rake, but the local guy wants $400 to rent one. I made a drag-behind thatcher with flexible steel tines, but it would take many trips to do anything - hence the thought of using the mid-mower. Now that I have a bigger tractor and 72" mower, it just sits anyway. Thanks! Also, it seems 16" is the biggest dethatcher mower blade available - true?
