7 or 8 ft Cutter?

[Limbhangers]

This is not a "can my tractor handle it question". I've got a batwing on a tractor that's too big for this job (can't maneuver) and I'd got a little compact tractor with a light duty 5' for cutting around the house that is too small for this job. So I picked up a 70 pto horsepower tractor to fill the gap.

I'm trying to decide between a 3 pt - 7 ft cutter would be single spindle or 8ft double spindle. Assume both are going to have 100hp gearbox. I would be cutting what would look like CRP , using for road maintenance, food plots, and fire breaks a lot of cleanup around the edges of fields, food plots, etc.

I will not be doing a lot of pasture/grass, improved type land.

Acreage wise... assume it is more than I'd ever have time to do. Several thousand. I lease to a couple different hunting clubs. I'll never get it all before I need to cut something else.

What would you be looking at?

I'm worried about tearing up a dual spindle 8 ft. unit. I've never owned one but have always been told this kind of work described above is rough on the gear boxes.

On the flip side a 7ft cutter is big and in particular long. I don't have a FEL which will help overall maneuvering but an 8 is much shorter and not a whole lot wider on either side. Also when you are dealing with unimproved places things are particularly flat and I am not sure the 7ft unit won't be eating dirt every time I go over a bump. I'm not taking a box blade down miles of fire breaks and smooth them out like a driveway.

Next problem.... width of a dozer blade = 10ft. If I push out the fire lanes with that blade width..... That's tight for an 8ft cutter


I hope that is a satisfactory explanation.

I've pulled both with M7040. You want the twin spindle one.

8' for sure. Pulls much easier and doesn't stick out nearly as far. I have had an mx7 and mx8 and still have the mx8 for a reason. For my place, I brought in a track hoe to remove trees so I can use the batwing. It's much quicker than the smaller ones. Is it feasible for you to do some work and keep running the batwing?

Is cut quality a concern?

The 8' will pull easier, be handled by the tractor better.

The 7' will leave a better cut in the conditions you describe.

A shorter deck, like the 8' will have, leaves the tall stemy vegetation pop back up after cutting alot more than the longer deck will. Its physics. The cutter deck lays the stuff down and it goes under the deck to be cut. The cutter is still holding the stuff down and it isnt until the vegetation clears the front of the cutter that it is allowed to stand up (under the deck) into the blades to be cut. On tall stuff, by the time this happens the base is already out of the back of the cutter where it stands up.

This is one of the issues I fight with on my 8' cutter when getting into 6-8' tall goldenrod, queen anns lace, etc. I can crawl through the stuff at a snails pace. Less than 1mph. Still stands back up. So I just go fast and mow it twice.

A longer deck will leave a much cleaner finish in one pass.

Go with the 7'.. you will get better results and you can throw this mower where you want it. I've got 2 pull type heavy duty mowers 15' batwing,10' pull type. I also have a 7' heavy duty 3 pth. Pull types r good for speed and volume but you can't beat a 3 pth for tight heavy or lite work. My 0.02 cts

I appreciate the replies fellas.

Just to be clear either size cutter is going on the 3pt lift...... I'm not looking at a pull or a semi-mount setup

Rather than a 2 spindle cutter perhaps an 8-10 foot flail mower would be better as it is much, much, much shorter than a twin spindle rotary cutter and you do not need 100 HP for a 8-10 foot flail mower, your current tractor will have plenty of power for a 8 to 10 foot flail mower. A flail mower of any size is much much shorter than a twin spindle cutter. A flail mower has a right angle gearbox that connects to a cross shaft that has a drive and driven set of V belt pulleys that spin the flail mower rotor.

With your mowing needs I would look at an Vrisimo flail mower or an Alamo flail mower.

Did you even read the OP's post??? Especially this part, "I would be cutting what would look like CRP , using for road maintenance, food plots, and fire breaks a lot of cleanup around the edges of fields, food plots, etc.

I doubt you have a clue as to where and what type of work this person is referring to. A flail is not what he needs to succeed!

As much as I dislike your tone & constant hate on flails, I do have to agree with you here. Out in the middle of nowhere, so minimal benefits from flails enhanced safety. Not a big deal for cut quality either im betting. A rotary will be cheaper to buy & maintain.

I do not hate flails at all. Flails have there place, but in the case of the OP here the answer is clear. I just can't stand people giving terrible advice that could cost people money. I think most have given up challenging him anymore or simply have him on ignore.
