Hello folks. Opinions/advice needed. We currently have a 3038e with a Frontier RC60 that we have been using on our 5 1/2 acres plus. This was the right solution 2 1/2 years ago when we bought this land. The land was uncared for and had lots of brush and debris. That is all gone now and "natural" grass has come in it's place. We now "finish" mow with the 3038e/RC60. It's not a total of 5 1/2 acres as there is one section that is heavily treed-probably about an acre. We have a trail in that section. And then there is my son's house that he built and then another old stone house. Maybe 3 1/2-4 acres. There is an unused road right of way through the land that likely adds at least a 1/2 acre and then we mow the highway frontage which has to add another 1/2 acre. So approximately 5 acres of relatively flat land with lots of tree's and other obstructions. Using the tractor is cumbersome and it probably takes about 4 hours of tractor mowing that consists of lots of manuevering and then another 1 1/2 hours of push mower and string trimmer to get 'er done. We think we want a zero turn and are looking at a Z500 series-probably the Z540M or R or if I had my druthers the Z915e. We have not looked at them up close yet. The commercial grade is probably the right tool as the land still has rocks-we intend to pick them up and get the land "Z friendly"-it's RC friendly now-but there is a big difference. I'm amazed at how much abuse the RC has taken and has kept on ticking. The question is if adding a Zero turn to the arsenal will effectively reduce our mowing time. I've seen many comparisons between the lawn and garden tractors versus the ztrack's and the ztracks are substantially faster-but what about the 3038e/RC60? The 3038e/RC60 does a pretty good job of cutting and is fast in the open spaces. Just irritating around obstructions. We would still use it for some of the frontage cutting-some of the frontage is wide and flat and beautiful grass we would use the z track for that-other frontage is "ditchy". Thoughts? And would we be happy with a 500 series? Or even a 300 series? I know the 915e would be awesome to have-but the money-$8500 plus is getting beyond the feeling of would it be stupid to spend that much money for a mower to be used on 4 acres on a weekly basis feeling. I'm posting the same question in the Ztrack section as well.
