Mowing Belly Mower Help

   / Belly Mower Help #11  
Bill,
Here's a scan of the "tractor mounted" parts for the YMM-60. This deck is driven by the rear pto with a large pulley (around 12" diameter if I remember right). This might be a less expensive alternative, but would require quite a bit of fabrication. Since your's is a YM1100, it should have higher pto speeds, so wouldn't require the 12" pulley. I think I figured out that an 8 or 10" pulley would work for the YMM-45 with pto at 1300 rpm.

I hope this helps.
Greg

I didn't mean to come on quite so strong.
Yanmar packaged the Operators Manual with the Mounting kit, so when a dealer ordered a kit for the YM155, it didn't show the parts for a YM135, and vice versa.
There is about 3" to 3 1/2" of lift before the guards contact each other, almost as much as on a YM155, both those models used the same size Ag tires (5-12).

gbirky,
Do you remember the first undermount mower that Yanmar had for their tractors? The 'Ranger U34YM and U35YM' ?
They both ran off the rear PTO like the YMM60.The model numbers meant-Undermount-3blade -4'-Yanmar Mower, which fit the YM135 and 155.
And Undermount-3blade-5'-Yanmar Mower, which fit the YM195 and 240.
Man, talk about "clunkers"!

No, I'm not a dealer, and didn't get into Yanmars until about 3 years ago. Were those U34YM's built by Continental Belton? I had heard from a local Yanmar dealer that these were OEM on some the Yanmars made for U.S.

What made them "clunkers"?

The Continental-Belton mowers were marketed by Yanmar as the YQM (Yanmar Quick Mount) series.
The Ranger was actually built by Allied Mowers, Division of Central Quality Industries Inc. in Dixon, IL.
I always referred to it as a clunker, but it really wasn't too bad of a mower if you switched to hi-suction blades, because it was a flat deck mower. At least it had grease fittings, so they could run forever. One of my customers still has one that he uses regularly, that he purchased in June of 1977!

While we are on the subject of Yanmar belly mowers, are there hi-suction blades for the YMM-45? My YMM-45 leaves strips of longer grass where the front wheels pushed it down. I know I can help the situation by putting weight on the 3pt, but I just haven't gotten around to that counterweight yet.

I really would like hi-suction or hi-lift blades for the YMM-45.

What I really didn't like about the Ranger Mower was being driven from the rear PTO when the tractor doesn't have a live PTO.
I have two suppliers for YMM-45 blades but neither one is really a hi-suction. Have you tried welding a piece onto your blades to create more lift. If you try it, be careful to keep the blades in balance.

Thanks for the suggestion. I have considered welding a piece onto the original blades, but really don't know how to do that to create more suction. Has anyone done this before that could provide some instruction?
