Just to be clear ... I wasn't recommending a finish mower for the OP ... It's what I'm gonna buy to mow every few weeks ...

Well OP: don't jump the gun yet. the last post does bring up a good point. it's all about the overall hanging length/ weight on a compact tractor. if you have one, look at the owner's manual for implement specs/limitations.

you might also want to discuss with your dealer's impartial advice on the subject since you're not going through them.

you're on the right track for now, do some more homework before you buy.
assume you have fel & loaded rears as well for the task. i've read where some load their ft tires as well, best regards
having said, would not recommend finish mower of any type.

I checked my operators manual and posted the specs. recommended, which is 84'' and 1000 #.
I did discuss the price of a land pride mower with local dealer. they recommended 7 ft land price at about the same weight at the LMC cutter I'm looking at for $3500.00 the land pride is stamped steel deck where the LMC mower uses 5'' channel for the sides. I've seen too many of these land prides around me with the sides and rear bent all to heck from hitting things . Not going to bend this LMC with 5 '' channel sides.

I already own an LMC 5 ft cutter with 5'' channel on the sided I have used for years and have never managed to bend that channel. That's the mower I'm using now but it won't cover the rear tires, so I'm wanting at least the 7 ft to cover the rear tires

Curious why the manual recommends up to 84 inch 1000 lb cutter when the other specs say it can lift 2,400 lbs 24 inches from the lift point unless they have figured out the effect of additional leverage when using an 84 inch cutter?

I can't answer that one. All I can do is tell ya what's listed in my Kubota MX5100 manual, and that's also what the Kubota dealer told me. I assume he read it from the Kubota manual as well

I am curious how kubota decides their size recommendations. If the 8 foot twin weighs 1500 lbs but is shorter in length, I wonder how much practical difference it would make compared to a 7 foot 1,000lb single cutter?

I have a L4760 and have a Titan 8 foot dual gearbox cutter. It loads the tractor down the same as a 6 foot. I bought the 8 foot used and it was the best purchase I every made. Years ago a dealer advised that a 8 ft dual would not drag down the tractor as much as a single gearbox 7 foot. The L 4760 handles it very well. Also, the cut it gives is very good also.

I don't think an 8' cutter (even a twin) is going to have the COG 24" behind the pins.

My biggest concern would be the weight. Any chance you could get your tractor to the dealer and try the cutter just for mobility? Power wise I expect it would be OK, though you may have to slow down in some conditions.

good thought, was just about to suggest the idea. it's the only way to know if it will work.

Thank you dnw64 for pointing that out. The twin gearbox assemblies may move the COG further rearward than the cutter length itself would indicate.

$3,500 for a 7 foot cutter that is near Kubota’s specs vs $6,500 for an 8 foot twin. Seems like a lot more cash at risk if the twin is not satisfactory to the OP.

Wonder if the dealer has a demo or used unit to test?
