I finally got the 2072 frontier finish mower hooked up to the 2520,all I can say is it cuts as good as any mower out their. I cut my grass when it was wet and the 2520 had the loader on and the weight of the tractor was not an issue.It did not leave any tire marks or mower wheel marks on the wet lawn what so ever. I am very impressed with the way the mower cuts and the way the 2520 handles it. I mowed in 2 wheel drive and never had a problem with traction.That 2072 is one built machine and bonus bought it at auction for 910 dollars out the door. I am ready for next years mowing season. Once again would like to thank everyone on here for their input.
