Adjusting Mower Blades

Postby Roshambo » Mon Jul 31, 2017 9:06 pm

:tractor:

Hi!

Well after a day of sweat I was able to remove the three mower blades on my Woods 59 with nothing but a 2x4 and cresent wrench...

Kept everything together like I took it off, soaked in diesel, reground/sharpened/balanced blades via benchgrinder and oiled them.

Now I've reinstalled them loose except for the middle (which is hard to get to so I tightened it down, hopefully enough..) but question is how should the blades be turned to maximize cutting output? (I.E. what position on the clock if the front of the tractor is 12 o clock.)(further I.E. right blade at 2 and 8, middle at 12 and 6, left at 10 and 4)

Maybe it doesn't matter. Eager to hear back and ty.

When sharpening blades a hand grinder allows you to get a better angle , closer to the angle that the blade originaly had , also when using fairly new blades you can keep a real nice cutting edge with a big fat flat hand file , I sharpen blades once a week the angle of the edge makes a differance in the quality of the cut and dull or wrong angle of the cutting edge will make the mower labor, another way to determine if the blades are cutting good is look at the fresh cut grass, a good edge will give a nice clean cut on the blades of grass and the grass will be standing, a dull edge or wrong angle will rip the grass leaving a jagged rip and the grass will not be left standing it will have a tilted leaning look .

Grass cutting technology 101 :wink:

If you're worried about the blades hitting each other, don't. The blades won't hit each other. That's why the middle blade is a few inches offset towards the front of the tractor. It's just far enough ahead that the blades can't possibly hit.

I think the biggest key to the mower deck is to make sure the front edge of the blades are slightly lower than the back edge of the blade. To do this, park on flat pavement, set air pressure in tires to spec (this is important) then orient the blade front to back, measure distance from ground to blade on the front, then measure ground to blade on the back. Adjust mower deck hangars so that the front edge is 1/4" or so lower than the back.

Good point. I've wondered that myself, but never had any issues. Still, I make sure to "clock" my blades to keep them away from each other.

How tight should the belt be adjusted on the Woods 59? I recently replaced the belt and it keeps jumping off until it broke. First day. The old belt didn't jump off and it wasn't extremely tight. I've been using B205 belts. I didn't have problems before, keep spindles greased and I don't feel any play in them. They also don't look like they've moved.

Check the alignment of the idlers with the PTO. Has to be a right angle turn.

Welcome.

With the mower deck in mowing position, there should be some where around 1/2 to 3/4" deflection in the belt. That is be about half way between the idler pulleys and the center deck spindle. So, belt is not that tight.

When purchasing belts, order the premium grade belts instead of the standard grade.
I have an excuse. CRS.

Agreed, KEVLAR or equivlent will last a lot longer and more trouble free.

Hi rappick,

Below is a page from the Woods 59 owner's manual, it tells about belt tension at paragraph 6 on the page. It says "Run belts very tight."

The next link is a page showing the belt routing, it has the have the twists the right direction.

Below that is the whole owner's manual. :)
