Woods 59 question

I have a 59L on my Farmall A for mowing the yard. In thicker grass the belt slips on the left side blade. I thought it was the belt so I replaced it - still the same. The belt is good and tight.

I also have a regular 59 (right side) - it does the same thing on the right blade. Is this just the nature of the beast?
 
Are the side shields off and how tall is the grass and what gear are you mowing with. With engine off turn the blade so the tip is forward it should be at least 1in lower than the back. and what height ia the mower set to cut should be at least 3in. How tall is the grass you are mowing. Those mowers are great but things need to be set correct. Something is not rite for the blade to stop. Ive been mowing with one for at least 40 pluss yrs.
 
Blades need to be sharp. In tall grass (6") you may need to make two passes, one with mower partially raised. The Woods Mower book says the belt should be very tight, they say "more belts fail from being too loose than from being too tight"

This mower is for lawns and not for tall grass.
 
The pulleys could be worn. Look at the bottom of the v grove. If the belt is bottoming out, as in the pulley is polished from the belt running all the way against the bottom of the groove, then the belt is too narrow or the pulley is worn out.
 
can't say exactly, but with those side discharge, 3 blade mower decks, the ones you indicated are the ones next to the discharge, so they have to "blow" their own clippings as well as those from the other two blades. so i'd expect that would be the first one to slip. but i'd also expect it to bog down the tractor first.
 
You have a very durable and mostly trouble free mowing outfit. We have a right discharge 59 on a B and it has to be pulled way down before the outside blade stops. Usually the tractor runs out of ponies first. This mower has been on this tractor since 1974 and has thousands of hours in it and the belt is the only weak point I have found on it. The belt has to be very tight and the book even states that fact. It said the bearings are modern and able to take a very tight belt, or something similar to that. A worn belt won't pull it no matter how tight it is and a new one costs a lot of money for no more than you get. I have replaced one noisy bearing in all the years we have had it. Worn pulleys could be your problem too, as someone else said. Seems like the blades stop a little easier on ours than in the past so we might have worn pulleys too. Jim
 
I think it's the nature of the beast, although all the other comments have covered it pretty well. I believe that is the slack side of the belt so the belt gets tighter as it goes around the other sheaves. V belts are supposed to be tighter than most people realize, they make tension gauges for them.
