I was thinking I would need at least 8 ft cutter, but if I can mow 20 acres in 2 - 3 hours with a 6 ft mower, that is reasonable to me. The 6 ft cutter would be much easier to maneuver and haul. I was looking at utility sized tractors to handle larger cutters, but I really think the larger framed CUTs would be a better fit for all my other needs and property size. Starting to lean towards the JD 4320 / 4520 or Kubota
L4740 /
L5740. MSRP between these models equally configured (as close as possible) is not significantly different. Just have to wade through the old JD vs Kubota decision.
Dream on.
You cannot mow 20 acres in 3 hours with a 6' cutter unless you are speaking of ideal, finish mower conditions. It is unlikely that you can do it with an 8' cutter, absent ideal conditions and equipment.
I have 5', 6', 7', and 10 1/2' cutters and have been mowing for 40+ years. I use the 10 1/2' mounted cutter with an 80+ PTO HP FWA Super Steer tractor (extraordinarily maneuverable) yet would not expect to mow 20 acres in three hours except in ideal conditions.
I looked at the 5740 as a "first round" tractor and really tried to convince myself to buy one but thought it too expensive, too light and, with less than 150 CI, too little displacement for even my Woods BB720X, 1200 lb. 6' cutter, even though the small size, vertical drive pinions and other bells and whistles were attractive due to the exceptional convenience provided.
Ended up buying a 60+ PTO HP FWA MF with FEL, independent PTO, dual remotes (for those of you who do not know, dual remotes means 2 spools, 2 handles and 4 hydraulic connections (sorry, but a pet peave of mine)), 4 rear weights, six front weights and front weight bracket for about $6,000 than a similarly equipped Kubota M 7040 would have cost, and with the MF I can mow at 540 PTO RPM at 1750+ engine RPM, rather than 2,600+ engine RPM as required with the Kubotas to maintain blade tip speed. This, of course, saves wear and tear, engine hours and fuel.
No, I am not a MF guy and really tried to convince myself to buy a
L5740 or
M7040 but doing so simply did not make sense. I have 1993 B1750HST, bi-speed turn Kubota with 60" MMM that I use to mow my lawn and plow snow and absolutely love it. I bought it new and it has been, perhaps, the best new purchase experience of my life. In the nearly 19 years since I bought it, I have needed to do absolutely nothing to it other than lube oil and filter changes. Will probably keep it for my son to do with as he pleases when he settles my estate.
