I'm considering the purchase of a drum mower to be used for cutting hay (next year). I can buy a new drum mower locally for about $2600. That's about half as much as a disc mower. I can't affor a new disc that's for sure and used ones around here are almost impossible to find. If you do come across one it's either totally shot or is priced just under a new one. What is the down side to drum mowers? I only do about 25 acres of hay from very clean, flat fields. I'm hoping for some quick responses as I can get this one on sale if I order early in the week.

They both cut in the same manner. Any MFG's drum mower is more durable than their disc mower. The drum mower fits in the market segment just like what you have described. CCM's current price on a 165 drum mower is $2,100. They ship nation wide so you might want to check them out.

OK, I'll admit my ignorance... What is a drum mower? What is a disk mower? How are they different? Advantages or disadvantages of both? I need something to eat down and tangled grass hay, that my sickle bar won't touch. My generic bush hog did a terrible job on this stuff this year.. I'm running a real powerhouse - a Farmall 200! Advice sought!

Disc mower, Contra-rotating discs fitted with 2 or more replaceable knives per disc.An 8 foot mower typically has 6 discs. The discs themselves spin at 3000 rpm usually. A bit more power hungry than the sickle but almost unblockable.{The cutterbar runs on skids}The cutterbar is filled with gear oil.
Note the hydraulic ram to fold the cutterbar into the vertical position for transport.

Disc mower in use, with its protective skirt ( which totally surrounds the cutting mechanism )folded down. This prevents foreign objects e.g. rocks from been thrown out by the high speed knives.

Drum Mower
Here the knives are fitted at the base of contra-rotating drums which too typically rotate at 3000rpm or so. The drive to the drums comes from a gearbox at the top of the machine, ( unlike a disc mower, where the gears are beneath the cutting mechanism). The drums usually ride on freewheeling 'saucers'. In the photo, the protective skirt has been removed for clarity.

I bought a drum mower from CCM and I love it. The sickle mower will rust into the ground before I hook it up again. The drum mower cuts very close and has yet to clog up and cuts faster than the sickle. Chet

Hi: I bought a drum mower this year and like it very much. Cuts good, does not plug and will cut wet hay. Am using a 28 HP tractor for about 20 acres a year. No problem. Will not go back to a sickle bar.

If you have only 25 acres or so a year, then that drum mower should just fit the bill. OK I will admit, compared to ye olde sickle mower, the cut is not quite so clean and they do eat up the horsepower a bit, although I have seen 5'6" two drum mowers working behind 'MF 135' type tractors.(Dad used to run a 5'6" behind a MF 175 in first high, high multipower and she played with it )After a couple of weeks re-growth though, who cares? Not only that, you will never ever miss the chore of re-sharpening sickle sections,rivetting or bolting on replacement sickle sections, replacing or straightening points, replacing ledger plates unplugging the thing in laid or tangled laid crops... etc etc .

Hi i have no firsthand exp with disc but i bought and rebuilt a used drum this year. guy i bought it from swore i'd never go back to my sickle moco's after running this. really the only + i found is it never plugs what i dont like is it does not cut clean even with new blades (seems to be a trait of a rotary around here ) this is a 5'6 mower and 32 horse isn't near enough as it is verrryyy slow . IF you have heavy tall wet grass then it is better but in the right conditions a sickle will out cut it and use less fuel good luck with whatever you decide mike

We have contractors use the CCM drum mowers to keep their spec houses lawns mowed. Our CCM drum mowers will mow just like a lawn mower.
