Bent deck?

A few weeks ago I hit a stump, bent a blade, and killed the diesel. I put a new mower blade on but I noticed it is cutting a half inch low on the edge that had the bent blade. I did some measuring and with the blade pointed parallel to the tractor both tips are 3” off the ground. With the blade pointed perpendicular to the tractor the inside height is 3 1/4" and the outside is 2 ¾". The spindle does not appear to be bent. I suspect the deck itself got bent a bit where the spindle bolts on. The deck is level,

Has anyone experienced anything like this or have an opinion.

Re: Bent deck?

Not unheard of if you hit it hard enough.

Possibility you may be able to shim the spindle bolts to achieve closer to balance as long as nothing is broken.

Re: Bent deck?

When perpendicular, if both blade tips are showing the same measurement, when outboard, likely the spindle mounting surface has bent somewhat. If the same tip measures the same both inboard and outboard, likely the spindle is bent. Obscured has a good idea. Cheap to try the spacers and if it works, you're good to go.

Talking Re: Bent deck?

Hey! Going with some common mower sense I would guess that if the deck has been tweaked then if you rotate the blade 180 degrees, the measurements should not change. If the deck is bent then the spindle is now rotating in a different plane than vertical. If the spindle is bent then when you rotate the blade 180 degrees the high side of the blade will remain high and the low side of the blade will remain low. This should tell you where the problem lies. As mentioned previously, if it is a bent deck you may be able to use washers to shim the spindle back to vertical. Bill

Re: Bent deck?

I bent the deck on my ZT less than a year after I bought it. Took the spindles out and with a combination of C clamps, a piece of 4 x 4 and a dead blow hammer tweaked it back.
I spanned the 4 x 4 over the bottom edge of the deck and used the C clamps thru the spindle hole to keep a strain on the skin the way it had to go and massaged it with the dead blow.
Was a time consuming tedious process but i got it fixed...............Mike

Re: Bent deck?

What Mike said.
I bent the left side mount and used a very similar process on a 48c deck.
Hers a tip also. Remove all your spindles from the deck.
The reason is so you can use a straight edge and slide it across the three mounts
and they should all be in the same plane.
When its right you will know.
I used angle iron to actually bend the deck back in place using c clamps and
4x4 as mentioned. It also served as the straight edge as well.
I clamped it across the deck side to side. Heavy 1 1/2 inch iron.
Have the deck on saw horses so you can work on it.

The guy, Taryl, somewhat of a comedian, has a video on youtube about that very thing.

Re: Bent deck?

I am going to try the shim route. I calculated that I need two .080” shims. I have some 5/16” washers that are .072”. Close enough for gummint work.

I’d like some advice about getting the belt pulley off. I figure to use an impact to get the nut off but will I need a puller after that? Any tricks you guys know about that? Does it have a keyed shaft?

Thanks, Al

Re: Bent deck?

The pulley should come off with little or no persuasion.

Re: Bent deck?

I had a CCGT2550 that I ran over a small stump with. The middle blade took the hit and the four tabs that hold the spindle were totally offset. I pulled the deck, took the spindle off and found that the rust on the deck where that spindle bolted on had weakened the steel of the deck. I bought the reinforcement ring, tapped the tabs into alignment, installed the ring and remounted the spindle. It worked fine after that.

Ha ha ha ha ha ha! I hope you are right Jay! Not my experience though. Actually, I have had good luck leaving everything on the deck but flipping it over and using the blade as the lever to level the spindle. That way you can rotate the blades over and over again until it is perfect. Pay close attention to where any two blades come tip to tip. That is a good indication of left/right setting. Then line all three blades up fore and aft and use a level or straight edge to see how the line up. I used a 2x4 under one end of the blade and it worked just fine. After all, you are only bending thin sheet metal compared to the thick blade. If it looks like you will need more force, have someone stand on the other end of the blade as you pull up on your end. I've straightened about three decks over the years so it is not that hard. Good luck with it.

Re: Bent deck?

I finished the project. When I removed the nut from the pulley with my impact the blade fell to the floor with the spindle attached. There was no resistance to removing the pulley, it actually sort of fell off. I cleaned things up and mounted the spindle back on with two 5/16 washers that were .070” thick. I had calculated .080”. I also greased everything.

When done I checked the blades on a level floor with the mower set at 3”. It was almost ½” difference before and now it was about 1/1 6”. I did a little mowing and it looks good.

It was actually a real easy, and cheap, fix. Last Friday I rented a Vermeer stump grinder and removed about a dozen stumps. I should have no worries now.

Rudy, I like the way you did that. If this does not work out I may try bending it.

Re: Bent deck?

I have spent a lot of time trying to pound deck shells back to level. I've given up on it and now just shim the spindles.
