Welcome Hugh.
While I don't own one, the Farm Pro is a product of China, and much of the metals I've seen in products from there that I've tried has been inferior to other brands. I would consider the Farm Pro Mowers as the most econonmy of the economy models, and thus more likely not to hold up to years of brush cutting.
Why not check out the mowers at Tractor Supply Company, the King Kutters, or find a dealer that sells Howse equipment. Both of those are econonmy brands, but hold up pretty well and don't cost as much as some of the big names such as Bush Hog, and Woods, etc.
