    Problems with the cutting deck

    Well, I think I'm on the right path... The base where the engine sits is actually flexing. I made a support for the front part of the engine, just below the valve adjustment cover and the improvement was significant... The deck vibration is now becoming acceptable... But if the shaft is not...

    Problems with the cutting deck

    No company returned positive information, always a “maybe” or “could be” and I will not pay for transportation and service that way. I returned the purchased part and worked on the old one, achieving a good result... better than the new one, but only in the oscillation of the pulleys, as I have...

    Problems with the cutting deck

    As consumers we are in a bad spot... B&S USA referred me to technical assistance. B&S Brasil, paid me a lot of attention, but couldn't say anything about the specification and couldn't even test another one from stock, as here they only sell it for the 17.5Hp engine, which according to them is...

    Problems with the cutting deck

    This appears not to be made of two halves but rather hot formed and then welded to the shaft I believe in a standard form and welded by machine... even so, there is human interference in the operation, where the greatest probability of error lies... perhaps in the rush to produce.

    Problems with the cutting deck

    Well... I ended up buying a new pulley... but... it also shows the same symptom, less so, but it does. See that the lathe bench even vibrates at high speed (700RPM). I'm asking B&S to find out what the vibration specification is to condemn the new pulley.

    Problems with the cutting deck

    It's already in my plans to remove and evaluate, I haven't done this yet because the tractor stayed in place... I had to return with the empty trailer for another activity. I even have to take measurements, as some sellers are private importers and have never seen a lawnmower tractor in...

    Problems with the cutting deck

    I wasn't successful... some, like Jacks, report other models or B&S brands.

    Problems with the cutting deck

    An internet seller says this pulley is the same for Murray and Husqvarna LT 131 and LT 151. Do you confirm this?

    Just like I didn't understand!?!?

    Problems with the cutting deck

    Well, unable to turn the engine shaft very slowly, I tried to set the lowest possible speed by moving the carburetor and the problem is now evident, leaving no doubt (for me) that this is the root cause of the deck oscillation.

    Problems with the cutting deck

    I agree that the cutting speed is always maximum, but I use it a little lower for sites with only leaves, which don't need high RPM. As I said before, it could be that I am very demanding and if the low is resolved, the high will be very smooth. Without the weight of the cutting set, the...

    Problems with the cutting deck

    I think I'm working with cold iron... everything I've been doing seems to have little or no effect on the vibration item... it's possible there are several causes and I'm eliminating each one, but the main one remains. I don't have anything to turn the engine slowly, so I removed the spark plug...

    Problems with the cutting deck

    Evolution: I placed an angle bracket with several holes that represent different angles of the steel cable to the axis of the tensioner pulley support... in relation to the initially chosen point, the vibration improved a lot in holes 2 and 3, getting very little at maximum rotation, but at low...

    Problems with the cutting deck

    No answer??? I believe it has to do with the adjustment of the belt tension, because from this hole the brakes start releasing the spindles and the belt engages in the grooves of the pulleys, transmitting the movement of the engine. One more question: The pulley engagement lever describes an...

    Problems with the cutting deck

    Does anyone know how to inform the function of this coincident drilling? https://youtube.com/shorts/FKgPIvgYJqE?feature=share
