Flail mower revisted:
I am using this mower too cut a path around the woods. and I keep burning belts up. After I got the mower back I tried too turn the cutter bar and it was very hard too turn. My to be next move was too remove the cutter bar and inspect the bearings they seem to be ok. I am wondering if I am missing a piece or part.
I did go to Messicks parts and found what they call a scraper but I dont see that on my very used flail mower. Does the scraper hold down long grass before the blades cut it? Does anyone have a picture of there 918L or can someone tell me how the flail mower is suppose too work? I get the flailing blades but is their somethingbending the grass over before it is cutt?
Ok a few things I /we would like to know first before I shoot my mouth off after brushing my teeth with gun powder :laughing:
?????:
1. what is your forward speed-it should be very slow to begin with.
(the slower the speed, the finer the cut, the more debris is knocked down)
a. burning up belts is a sign of overloading and or to fast forward speed while cutting.
2. what is the engine speed in relation to the proper PTO speed of 540 RPM.
a. you cannot use a flail mower with a low engine rpm and 540 rpm at the PTO and expect it to work well (not going to happen)
3. how often do you grease the ROTOR BEARINGS? You should pump 6-7 shots in each bearing before mowing as you do not want to blow out the seals on the spherical roller bearings.
a. if you are trying to spin the rotor with the pto shaft attached to the tractor and the belts under tension it will provide a very large resistance as you do not have slip clutch on the drive pulley. Your trying to rotate the rotor rather than the tractor driveline, gearbox, shaft, pulley and V belt to final Pulley and the rotor.
b. The only time you remove the rotor is if the bearings are cooked and the rollers are falling out of the bearing housings
4. If the rear roller had scraper most likely it would be there or there is a point where it can be mounted.
a. the job of the rear scraper is the shear the wet grass off the rear roller to keep it from plugging with wet clippings and in the process become larger in diameter and elevate the mower which would leave taller grass and brush.
I want you to suceed and not to fail.
