Im thinking 36 is kinda high,I think you could get into a new 6040 for around that price havent checked but I did just get a price on a new 8540-4x4-shuttle-cab-ldr and it was 42,500. But as a owner of a 7040 and 5040 if the tractor has been taking care of I wouldnt be worried about the hrs. I didnt catch on how many acres are pasture and how many are woods.I would say that 70hp isnt over kill unless you have mostly woods.I have a lease place thats 100acres 80%pasture and used the 5040 (this last time)with an 8ft shredder, mowed for 6 days straight and still didnt get all of it done...(just really depends on what type of grass/brush you have and how much you care about it looking).Some folks mow once a year and others like myself 2 to 3.
