New blades for 1850

[AltavistaLawn]

The most important thing is to buy longer grade 8 bolts. Then use two grade 8 washers to hold the blades. I've had them fly off before this, after the stock washers got worn....scary deal.

We go through too many blades, but we also mow some rough places, so I expect it. I wish I could find some cheaper repalcements.

For finish mowing, you need lift, all of my finish mowers have high lifts on them. But the PT deck isn't baffled, so although lift blades will help, it may never perform like a finish cut mower.

A though would be to get a 72" 3 PT hitch pto mower; then remove the gear box and fit on a hydraulic motor, and mount an adaptor plate to it, and use it with the PT.

Bill... Thanks for all the tips. Yeah, I tried for a couple of weeks to find a blade solution. These 1/2" blades are really nasty on the rought stuff.

Good info on the washers. I upgraded the bolts but didn' think about upgrading the washers. Back to Fastenall this week...

We don't have any lawn per-se. But as we get the tall blackberries back we are laying down grass seed. Just to choke out the blackberries..

Hey folks,

Just a dumb question; what are the extra bolts doing? Is their function solely to prevent the blades from rebounding and swinging 360 degrees?

Is it worth unbolting the bolts on my new mower and replacing them now, before they break?

Thanks,

Peter

IMO, yes on replacing the bolts. They will break.

The extra holes are in case you do break a bolt, you can put the blade into the other hole and keep mowing (both blades would have to be moved).

Now, this would assume you have a bag of washers, spacers and bolts on the tractor.
