Offset: The TL1500 has a fixed offset to the right (looking forward). My B7500 is 50" wide across the rear tires sidewall-to-sidewall, so the TL1500 cuts about 12" beyond my right rear tire, while on the left side about 3" of the rear tire width is uncut. My MMM discharges to the right, therefore I am used to doing my close trim work on the left side. With the TL1500 flail my close trim work will be on the right.
More Observations - Second Cutting:
I just finished mowing my 5 acre pasture for the second time this year. Most of the grass was 8-10" high. The flail was still on the highest setting, about 4".
Horse Power: No noticeable engine RPM drop during this cutting.
Noise: I guess I am used to the difference in noise, because I didn't think about it until now.
Chaff: Did not clean the cooling system in 4 hours of flail operation. Coolant temperature never went above normal. Nothing hit my eyes, nose nor mouth. :)
Cut Quality: I have mowed this pasture with a RRM, MMM and now twice with the flail. IMHO, the flail gave the best finish this pasture has had. No problems with clippings accumulated on the right side skid. I am extremely pleased with the cut quality when cutting reasonable height grass.
Weight: I changed directions faster than during the first cutting, and did experience some lifting of the front tires when switching from reverse to forward. Might look for some front weights.
Gear box oil: Still no oil out of the dip stick hole (extension) after the first 14 hours of use.
Ground speed: I mowed in high range this time. I didn't seem to be going faster, but I was more efficient. No going back recutting anything! It took me four hours rather than five hours.
Conclusion: Keep my name on the list of happy flail owners! :)
After fighting a 6-ft Caroni RFM that keeps eating belts for the past few years, I bought the TL1500 flail as well, partly based on the information in this thread. My only regret is not doing it sooner. It ate through wet hood-high pasture grass without even blinking. This is a great mower for smaller tractors like my B2910. It took me about 1/3 less time to cut 5 acres of pasture, which also means less diesel used. I agree with all that Rusty said about this mower.
I've had a Caroni TL1500 for about two months now, pulled behind a MF 1526 which has 20PTO hp. I'm on the Colorado prairie so all the grass has been browned up before I got the mower, but I've cut a few acres of that to see how it does. It cuts the 12"-18" dry grass fine except it doesn't chop it up much. I also have a bunch of Colorado yucca that is up to two feet tall. The tractor and mower really can't handle the bigger clumps of that. Running over a big yucca plant can stall the tractor out. Smaller plants are okay but may still pull down the rpm by several hundred depending upon the size of the plant. I had thought the mower belts would slip at some point but they do not. Seems the belts on the Caroni have more resistance than the tractor engine. I'm thinking I may have to see how loose I can set the tension on the belts-- most comments on flail mower belts seem to be about increasing the tension.
For what its worth-
Do not loosen the belts-gasp!!!!
I wanted to mention to you that backing over heavy brush
at the 540 rpm engine speed with the mower operating
at ground level is a good first step in knocking them down
to the sod with your flail mower or any flailmower for that matter.
This is the same thing Island tractor does with his Caroni to
get rid of/manage his wild berry bushes.
OK. No loosening of the belts.
I have not tried backing into these things, so I'll try that.
Have tried raising the mower to about a foot, but for the most part that shreds the heavy yucca leaves rather than cutting them. Sort of goes from 100 leaves to 100 leaves on the bottom half and 10,000 strings of leaves on top.
As Leonz mentioned, backing into brush works very well with these flails. It cuts partly on the backing but mostly knocks brush over so you can cut it when you drive forward again. Just like backing into brush with a bush hog. Back about three feet then forward three then push back into fresh brush again.
Follow up on my attempts at mowing yucca with my MF 1526 and Caroni. Here's what the stuff looks like. These are some medium sized ones which when mowed over will pull the engine RPM down from the normal 2600 at 540 PTO speed to about 1800 RPM.
Here's a big one one that I was working on. This thing had killed the engine three times at this point.
Finally got it down as far as I could by going over it slowly and dropping the 3-pt about an inch at a time. About fifteen minutes total on this one big yucca. I've probably got 50-100 of them about this size. The flail mower chops it up into something that looks a lot like the old excelsior type packing material, if anyone remembers that stuff.
Overall I think the Caroni can probably handle this stuff, but my tractor doesn't really have enough horsepower for it. The 20 PTO horsepower that is really about 17hp at my elevation probably needs to be about 25 real horsepower. On the other hand, it is all I need for most of my ground and I really like the physical tractor size. Also I wonder if I might have done better with the Caroni that has fewer cutters. At any rate it is supposed to snow on Friday, so I've put the mower to bed for the winter.
