Finally serviced the 710 deck on the massey 8 today. Tried mowing with it and it seems to not be cutting the grass very well. I put new grease in the gear boxes, sharpened blades, installed new belts. It doesnt seem to be bogging down when its cutting. Idled up the engine a bit and it didnt make much difference. Doesnt seem to be throwing the grass very far. I timed the blades per the manual. The tractor is in the higher speed arrangement right now, so should i change it to the low speed arrangement and just go slower when I mow? Or did I miss something else? Please help!!!

Are you cutting at full engine speed, 3600rpm or so?

 

Are you in 2nd gear when cutting?

 

I think your suppose to put gear oil in the mower deck gear boxes. ???

I know diddley-squat about Massey tractors, never owned one although I would if I could find one. 

 

Are we sure the belt is the right size?  It sure sounds like it is slipping.

I had a Massey 7 yrs ago, same mower deck, and found that if you put grease in the gear boxes it really loads the motor down or the belt slips.

Too much resistance to turn the mower deck shaft.

not 100% sure if i am at 3600 RPM's, But I was running at full throttle, and I set the Throttle up a bit higher and it made little difference. belt is good and tight when its engaged, But I will check it again.

So would a heavy weight gear oil be better to use in the gear boxes? Could it really be creating that much drag? Enough to slow down the deck?

I think so, on mine it would slow the engine down, you have a 8hp motor more power, maybe in your case the belt is slipping a bit as superaben said.

I was using a light weight gear oil in my gear boxes, seemed OK.

I never mowed with a MF8 but I heard a few times that in 2nd gear they work really good, fast and maneuverable.

I'm not sure I follow exactly the issues you are having with the deck cutting grass.  You state it doesn't throw the grass far, but mine usually only throws about 4 to 6 feet depending on how things are going.  Is it leaving a stripe down the middle?  Could be your blades are too short, or are dull on the ends.  Random grass sticking up and not being cut?  

If it is really not cutting well, you have an issue and it may be with your belts,(odd that you wouldn't hear belt squeal)  because I LOVE the way my Massey 8 cuts.  If you are in high range, I wouldn't cut above 2nd gear, and you might need to drop to 1st if the grass is thick.

they are definitly not upside down! I thought of that too. The washers were froze solid to the blades, so I left well enough alone. Im gonna check over everything today and see if there was anything I missed.

Ok, so today I changed the deck belt to an inch shorter one and adjusted the mule drive belt and it mows quite a bit better. The funniest thing of all, it cuts lower on the chute side than the other side. the rear roller on the chute side is all the way down and on the other side is halfway up. I have the deck approximately1/3 of the way down when mowing. I know that the parts manual lists a wheel kit for mowing a little taller. Any tips from anyone for leveling out the decks on these Massey 8's? BTW, this problem is funny because i think this is why this mower was parked almost 30 years ago!

Can you tell me what all I need to look for and adjust so I can LOVE the way mine cuts too?
