Can a 2038R pull a 10' flex-wing rotary cutter?

My answer would have been a firm NO! ...but I'm proving myself wrong!

Remember...my 2038r has been tested on a dyno at only 27 PTO hp. (not a certified dyno by any means, but our 1025R tested 25.5 PTO hp on the same dyno just a few minutes later).

In case you are interested, I go into great detail about the challenges I faced with 'fitment' for this mower to this small tractor. They are not major challenges, but they ARE items which need to be handled. ...starts somewhere around the 15 minute mark.

Excellent video. I know my 72 inch deck cannot make mine work no matter the speed or the depth. I can overrun the capacity of the deck but not the power of the tractor. I would still not believe that it would run a 10 foot more that well.

I don’t think you could get it to hook up to your 1025 but it would be interesting to see if there really is only 2 hp different when doing something like that.

By the way. Have you just not experienced enough pain in your life? Who picks up a live possum by the tail? I would not for love or money.

We were trimming today and played Tim and Christy. Trim it, throw it over in a row and used the TKV-20 to pick it up. Worked like a charm.:good2:

Its amazing what you can do with larger implements. It was hard to tell on start-up how much it bogged the engine down.
I'm assuming you engaged at low rpm. What about shut down..?? Are you runnng an over run clutch??

Tell us more about the .....unshown pto incident. I'm thinking the hitch point has to be directly under U=joint.

Wasn't/ wern't any good shots of that area. Looks like it actually turns quite tight. More than I figured the driveline would like.

Seems like it has too many wheels but they would provide a more level cut perhaps.

:munch:

Two of the wheels are optional. 4 are standard. The extra two in the middle help with stability.

Just need 14 inches from pto shaft tip to drawbar hole. Otherwise shaft is too long.

The error...
I had my drawbar in too far...not extended to the last hole. Has nothing to do with matching the ujoint over the hitch point. In fact this shaft has a double CV, so this would be impossible....as there are multiple ujoints.

Anyway...

I connected the shaft on level ground with mower all the way down. ...plenty of room for shaft to compress...I thought everything was fine.

When I loaded on the trailer, with mower lifted all the way up, the shaft could not compress enough...pushed the PTO shaft forward breaking the bearing holders, etc in the rear end.
After an acre or so of mowing, the shaft fell out on the ground exposing a hole in the tractor. I think we might have video from our drone of that part of the event. I guess I should publish this story in its entirety, explaining what I did wrong.

I was quite embarrassed, so it has taken me some time to be willing to talk about it. I felt compelled to mention as it is clear others are considering the mower for 2038r and other small tractors.

Don’t let this experience stop you! Just remember to extend the drawbar at least 14” from the top of the PTO.

There IS a sticker on the mower explaining this clearly!!! I’m just a blockhead!

Can a 2038R pull a 10' flex-wing rotary cutter?

Yes it can, I saw it on YT!!!:laugh: I'm still pretty impressed that a 2 series seemed to have no issues running the mower. I guess it's like everything else with these smaller tractors, as long as you know the limits, it should work, kinda like my 1025R I use on my 11 acres! Don't beat yourself too much Tim, we all have done some pretty dumb things before, and I admire your honesty and would like to learn more about the error so we all can learn!:bigthumb:

What I found in running my 10ft Rhino on my 4066R is that the momentum is so great that once you get it started, that momentum just carries you right on through the cutting. But it sure does groan in getting it started. The momentum is so great that you have to make sure you idle down the engine before shutting off the PTO or it will keep running for too long of a time. I also have a 110 inch RFM for comparison, but that momentum does not happen with it.

Haven't watched the video yet, but I know the answer.

Will it pull it? Yep, easy. It's just like pulling the 30' cultivator around the yard with our old 2640. As long as the wheels are up, you're golden! :laugh:

The real question is will it OPERATE it! (which I'm guessing was also a success).

This is pretty cool. I've been tossing around getting a small batwing for clipping pastures with. My tractor has the same HP as yours, and for what i'd be using it for, it should run it easy. For heavier stuff, i don't think it would do as well because its not turbocharged like yours. I have a 5' cutter currently, which I would use for heavy cutting.

I would imagine that from your previous post, trimming the pto could help some of the issues you had. I've read before that when you run a drawn PTO drive implement, you shoul have the pivot point of the front U joint and the hitch pin lined up, rather than extending the drawbar like you did. What do you think? I also wonder if some of the issues you had could be alleviated by simply using a 3 or 4 series.

Really great video. Thanks for sharing!

Really don’t want to cut this pto shaft. Just pay attention to the 14” minimum as directed by the sticker on the mower.

Don’t worry about the pivot point. This is a double CV PTO shaft. No need to overthink this.

The shaft is $1200 by itself, BTW! Not the same simplistic shaft as on a 3 pt mower or tiller. It has either 6 or 8 grease fittings!!

Yes, using a larger tractor would alleviate all of the fitment issues. I refuse to call them ‘problems’, as there was no problem with tractor OR mower. Just one time fitment issues.

I use the same mower on the 5075e. I have to re-adjust the mower deck level when I change tractors due to different drawbar heights.

startup vs running......we saw the running....missed the startup

looked like the hystat speed adjust ability worked good with the mower

seemed quiet on the video ....probably not in reality?

curious as to your actual average ground speed on open ground?

i occasionally pull a jd trailed mx8 with a jd 4500 (33hp pto) ...grunts on starting...does fair ...

intresting video:bigthumb:

It is hard to start at idle. I have to raise the throttle a bit (not much) to avoid killing the tractor.

The variable speed of the hydrostatic drive is what allows this mower to work with such low horsepower.
Don’t get me wrong, I’m not saying that it has more power. (Very likes less)...rather I could slow down when necessary to give the mower time to catch up.

I probably ran 3mph on average. Not sure. The heavy fescue made me slow down. ....and from the video you can hardly tell it. I thought I was slowing down a lot, but apparently not so much based on the video.

Yes, the mower is VERY quiet. We noticed that in a prior episode when pulling with Johnny 5. ...and mentioned it then.
