Good evening, I'm new to Ventrac and this forum and I'm looking for some advise. I'm looking to purchase a new Ventrac 4500 and I not sure witch would be better for my intended use. I will be mowing about 6 0r 7 acers a week. ( my own lawn) and my concern is it will take longer than it does now. I'm currently mowing with a Ferris is 5100 and it takes me 2 hrs. to mow it. I would like to stay diesel but I will be giving up about 7hp from the Ferris. my other concern is i have read on this forum that you should mow in low range and from what I read that is only about 5 mph. If this is true its going to about double my mowing time. Also I'm planning on getting the rough cut mower and power rake and was wondering if the 4500Y handles these as well as the 4500Z. Any advise would be very helpful. Thankyou
