rotary cutter 1st time to use

[chabat124]

Well, today was my 1st time to mow. I mowed a quarter acre lot that has grown up with bahaia (sp?) and some johnson grass.

I was mowing with my '52 Ferguson TO30. I fabbed up some check chains (limiter) to control the height of the deck. They worked Great! I had repaired the yoke for the tail wheel but the back was set too low and was dragging. So After a few near stalls, I reset the tail wheel height and finished the job. Now I think the back is a little too high, but I can adjust it again for next time.

Observations: I had to cut half width in bahaia as it is tough to cut, but that was when the back of the RC was dragging too.

On the near stalls, I clutched and the motor was just putting acting like it was going to stall. The only way I could get it going again was to put the throttle lever to full and the motor would rev up after 10-15 seconds (all with the clutch in). Then I would throttle back down some. There is a LONG delay in the throttle response. What I mean is you adjust the engine down from a high rpm and it takes a while before it actually comes back down.

I don't see how the brush hog could cut anything more than grass ie small trees as it bogged quite a bit in bahaia. Maybe I was just cutting too low.

I am somewhat concerned about the throttle response when it lugs. I am not sure if the tractor is having a problem or it is just user error.

I am still totally new to all of this. /forums/images/graemlins/tongue.gif

With the back end of the cutter low you are actually cutting every blade of grass twice as you move. Once with the high blades in front and then again lower with the rear end and the low swing of the blades. Setting your mower slightly high in the rear means half as much cutting and half as much load on your tractor.

Super thick dense grass and high ground speeds takes more tractor power than slowly chomping up brush. It's a totally different method.

Glad the chains worked.

Also, cutting tall grass down real short means the clippings get cut and recut, almost mulched while stirring around under the mower deck. Cutting too short will clog up the works and put extra strain on the tractor.

Check Chains pic showing how I attached it to the rotary cutter. This way I can adjust the height by moving up a link on the chain. /forums/images/graemlins/smile.gif

I am going to take a couple guesses on your throttle delay problem. First, possible issue with your clutch needing adjustment/replacement? Second, I'm thinking that a possible throttle linkage bind or maybe just needing oil to help lubricate? You've probably already thought of this stuff, but I figured that I would give you my two cents. Hope you're able to figure it out.
