Do you have the fork and spring?

(quoted from post at 19:09:51 09/23/08) Do you have the fork and spring?

it all seems to be there...the only way i see to tighten it is by tightening all the bolts on the pittman arm...there is a mechinism, but i dont know how it is supposed to fit together

Here's a place you might find a manual.

If you go to that other site Ntractor (Add the word club)dot com and search the manual section there is a 501 sickle bar mower parts manual there which may help you find what you need to known.

Go to New Holland dot com and pull up the online parts diagrams for the 501. Will show you if everything is there and in the correct order. Manuals are generally cheaper direct from NH as well.

You might open the NH website and look at the parts figures for your mower. The best I can remember on the attachment is that you align the mechinism over the ball and press down hard and it will lock on to the sickle ball. To remove you would take a bar or large screw driver and wedge between the ear and the fork in the pittnam and prise back and lift off of the ball.

Has anyone ever seen a 501 with hydraulics? I love my 501 but I'm getting older and the bar is getting heavier.

jtmcdon · Sep 24, 2008

I should have been more clear. I know the 501 didn't come with hydraulics. My question was, has anyone ever seen a 501 that has been modify to work with rear remote hydraulics.

There is a lever on one side of the mechanism that surrounds the ball.

You rotate that lever (short pipe, or tap with hammer, etc) 180 degrees to make it tight or loose - it kinda over-centers. It will clamp the 2 cups together.

There is a spring down there in the pitman wood, and so on - you might be missing several of these pieces if you can't see what I'm talking about?

If you would open your email, I could send you the manual page(s) that will show you what to do.

I had a similar problem with my 501. The new sickle bar I bought from TSC had a slightly smaller ball than the original. I hammered a washer into a dish shape, then welded the washer to the ball. A litle grinding and it worked fine afterwards.
