I have a 72in medium duty Land Pride rotary cutter that I run with a 35hp CUT. When I first got it, I was brutal with it. I was cutting anything I could run over, from super tall grass, blackberries, vines and small trees. It tore it all up and then some!!! I also tore up the cutter pretty bad. I've had to replace the drive shaft twice, three sets of blades, the tail wheel and the gear box. The gear box had a three year warrantee that was replaced for free. My deck is cracked in multiple locations that I've patched and rewelded. I've busted dozens on sheer pins and always keep several in my tool box.
I just told my dealer that my gearbox was making a very loud whining noise. He said to keep using it as it was shot anyway and when he got a new gear box in, he'd replace it. Since getting the new gear box, I've stoped cutting down trees with it and use it mostly for maintenance and extreme weeds.
I don't know about other brands, but doubt many people are gonna be as abusive on it like I was. Having admitted to all this, I'd buy the same cutter again. There's probably other brands that are stronger and would hold up better, but I kinda doubt that any brand would have made it through those years of abuse without similar damage.
Now that I have things under control, I rarely use my rotary cutter. I have a 84 inch Land Pride Finish Mower that I use for just about all my mowing. I wasn't looking for Land Pride when I bought it, but just got lucky when a client asked me if I was interested in buying a used mower.
Kubota now sells Land Pride products and parts.
