You can run a 6-ft sickle bar mower and a wheel rake with your Yanmar.
Running a normal size baler like my Massey Ferguson 124 (two-twine, small squares) can be a real problem although it has been done with small tractors like my Farmall Super A that has only abut 17 hp on the pto.
My neighbor tried to bale using his Ford 8N (about the size of your Yanmar) and an IH wire tie baler (two wire, small squares). He got the baler spinning OK, but he neglected to put an overrunning clutch (ORC) into the pto driveline and damaged the internal pto drive shaft when trying to stop the baler. There's a lot of rotational energy in the baler flywheel and you need the ORC to disconnect this load from the pto drive when stopping the baler. All modern tractors have the ORC built into the tractor's transmission. Don't know for sure if this is the case with your Yanmar. Check your operator or service manual to find out.
One way around this problem is to find a baler that has it's own on board engine to spin the baler so your tractor only has to tow the baler around your hayfield. My neighbor has one of these balers that he uses on his 8-acre hayfield with his Kubota 4520 tractor (which is has twice the hp of your Yanmar).
Your Yanmar probably weighs less that the baler (my MF124 weighs about 3000 lb). This can be a problem towing the baler when the hayfield is sloped or otherwise non-flat.
People have mowed hayfields with brush hogs. Usually the left skirt is removable to provide a side exit for the cuttings. The problem with this method is the possibility of chopping the mowed hay so much that it becomes difficult to produce tight, straight bales. That said people have successfully mowed hayfields with brush hogs.
Good luck
Good info from first hand experience.
The YM2610 has 30Hp for the engine and 26Hp at the PTO. The tractor has the overrunning clutch (ORC) since I did ask Fredricks about being able to bale hay with a square baler.
Even on their website it states ...
"During the rebuild, we also install a full safety package that includes a ROPS, seat belt, PTO shield and overrun clutch, and more. This is part of our commitment to provide a safe, reliable tractor that will give you quality service for years to come." -
Fredricks Importing
Hoye has them too....
Yanmar over running clutches
The YM2610 like most of the Yanmars has the multi-speed PTO. Thus, selection 1 is 542rpm and selection 2 is 685rpm. The other two are fast yet to run British, French, German or Italian older implements if needed.
I was told that the IH balers are trouble and require stronger Hp tractors. The MF or the NH balers would work fine. I've even seen a 1952 Ford 8N with a NH Super 66 sq baler doing the job well. An Allis Chalmers baler would work, but it's getting harder to find parts or knowing a local machine shop to fab things can get pricey. I was told to ignore JD balers since most are imports and have issues. JD has good tractors, but implements are another story.
The YM2610 weighs about 2,800lbs without rear wheel liquid ballast or the front 300lbs below the grill weights. So, it's possible to tow the baler around rather than the baler being a tail wagging the dog.
Yes, the neighbor used his front loader Kubota to bushhog the field, then came back with a 4-wheels wheel rake that did a nice job. Then he used his New Holland square baler. My Yanmar is the same compact size of his Kubota diesel.
Thanks again for your write up and experiences. It gives me something to draw upon.
