What is the proper way to mow weeds?
1/2 throttle and 1st gear? My mower clogs up all the time. I think I have everything adjusted right. Allis B with mounted mower. |

Depends on the weeds, standing tall or laying down and tangled? Down and tangled, good luck with a sickle even with sharp blades. Short weeds under 2’ or so I’d say 3/4 throttle and if it’s plugging your blades may be dull or sickle needs adjustment.

i cut our road side with a B with Sickle.... 1st gear and half throttle.. 2 ft tall or more --heavy grass mixed with clover / crown vetch / milk weed and everything else you can think of..... i can normally cut about 200 ft and it balls up on the outer foot BAD.. I have modified the foot, new blades, changed things around 10 times and it still does it.... This is not wheat or rye... Thick grass and weeds....
i normally cut 200 ft, then raise the bar and backup 20 ft to try to get the ball to fall off... then forward again... doesnt sound real efficient, but not too many ways to cut 6 ft off the road on a slope.. i cut 2 times per year.. if you did it every month it might be easier ... but more time is not part of my plan.. try to cut in the afternoon when things are dryer... wait 2-3 days after a rain.... it is what it is when your cutting WEEDS and not crops..

Sounds like (it may not be) a very dull sickle and guards and hold downs not keeping the sections against sharp guards. Water grass is the worst for not cutting that I've ever seen. We mowed hay at 5 MPH.

Ground and what you are cutting needs to be dry,new sections on blade does wonders and a B is pretty fast in first gear but we use to mow all our hay with one back in the 50's.
If its clogging on the outter end of the cutter bar you need a split section.

Thanks. It’s the weeds along the tree line. It plugs at the end and I back up to clear it

Tractor supply has the split end sections replace the one regular section with the split section and that should cure the problem

I mowed thistles, water weed, and other stuff this week with my 82S in 6th gear on my D17. Now I didn’t have a whole field of weeds just sporadic patches. Where it was thick it did just fine unless a water weed stalk went up under a tie down. Only way to free it was to remove it by hand. Otherwise the mower did great. I replaced all guards and sections this past winter. I use Hersel A+ sections and like Gary said a split section at the end. 1st gear on a B should work fine. Since you’re not mowing hay removing the swath board may help. Try that to see if it helps. That would allow it to fall over without being pulled back towards the tractor. If you’re making more than one pass that may not work well. Just an idea to try.

You are going too slow in 1st gear. When you cut the weeds, they are accumulating on the cutterbar. Try second gear and a bit more throttle so the weeds fall down after mower passes under them. As the Dr. mentioned, I would also checkout the knives and guards to see they are sharp.

Just curious have you ever actually mowed with a sickle bar on a B?

there is no way i could mow in second gear on my B... I have tried and it only works on very THIN PATCH areas of grass... Road sides are so THICK and full of CROWN VETCH and others , that you you will be PLOWING THRU if you speed up... half the grass wont get cut.
