2 - 48" Mower Decks

Recommended Posts

GLPointon
I picked up this Allis Chalmers 48" deck from E-Bay for $100. It has "like new" blades & 1 season on the bearings, only slight surface rust, good rollers & came with both belts...The only issue is belt covers are missing.




Does anyone know why it has an extra pulley on top of the main drive pulley?






The 2nd Deck I got from another member. It needed alot of welding but he gave me a new center shaft and a set of bearings with it. I got it welded up, rebuilt the spindles, got new blades and belts and a new paint job...Works Great!




its so quiet that now I know my 42" must need new bearings...RATS!

Looks like a later model bolt on pulley on top. they must have used the holes in it to pilot the holes in the lower one. Couldnt venture a guess as to why someone would feel the need to do that, unless they felt the lower one was worn and they couldnt find or didnt want to afford a replacement for it.

"its so quiet that now I know my 42" must need new bearings...RATS!" If that 42" deck has grease fittings, pump the arbors full, might take 20 pumps or more, then with the deck upside down warm up the arbors with a torch, heat gun or whatever to get the greae to flow into the top bearings. I have quieted down several noisy decks that way. Of course if the deck has sealed bearings and no zerks.... Looks like a nice deal on that 48" deck, they aren't getting any easier to find.

Larry, Thanks for the advice. My 42" deck only has grease zirk on the center arbor only. as soon as it starts to humm I imediatly go pump it full of greese again and that always helps. I was unsure on the rebuilt deck to go with sealed or unsealed bearings and grease...any thoughts ?

Maybe someone put the extra pulley on that deck so that it could be used both on FDTs and RBTs, since they have different size pulleys on their decks. The lower one does look quite a bit smaller.

Some of the B-200 tractors had a double-v belt that drove the mower deck. Many of them were converted back to use a regular belt through a kit offered by Simplicity. On your deck the top pulley is the single groove and the bottom is the double groove pulley. By having both style of pulley attached you could use it on tractors equipped for either style of belt, though the angle is increased on the top belt becuase of the higher pulley.

They are actually the same size. As Chris stated the B 200`s had the Double V pulley and the guy I got it from simply bolted a single over it because the belt for the double V are so exspensive. Not sure why he just didn`t remove it.

Thanks Nate, I made an offer of $25 on them...I think $35 is a bit high for 48" covers in that condition & w/shipping = >$50, but I'll find some...

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
