[AT] Sickle Mower Question

[Dick Day]

I have a New Holland 9' pull-behind mower (don't remember the model#).

I have already replaced one tooth that was missing.  I just punched the rivets out and bolted the new tooth in. Then I realized that the plates that apply downward pressure on the bar did not sit high enough to allow the nuts to clear. My friendly NH dealer explained that I needed a newer plate that allowed for the added height of the nuts, so I put that on and it works great.   However, I see that a number of other teeth are broken. 

The PO I bought it from also included a box of new replacement teeth as well as a brand new full bar of teeth (can you tell I am a city slicker?, feel free to correct my descriptions).

If I continue replacing individual teeth, I will also need to keep replacing those plates.  The dealer said that hardly anyone uses rivets anymore and talked me out of using rivets.  He is right, the bolts are so much easier.

Should I replace the entire bar, or just replace the broken teeth and keep buying the new style plates?

How hard is it to replace the bar?

What is the best way to get the old rivets out, a grinder?

I only use it to mow my ditches.  I put the tranny in low and use 2nd gear and keep it rev'd at 540.  Anyone care to share any tips for using the mower?  It works great but does seem to push down some areas rather than cutting it, possibly the teeth are dull.

Thanks!

Dick
