mower deck Problem(Update)

Recommended Posts

GWGAllisfan
The new 7112 I got had some work needed for the mower deck. Among the issues are that the rollers don't turn, showing evidence of sliding, instead of rolling. I can't even get them to turn by hand. I have several questions: I have two numbers in my book for the rollers 108432 and 1668513. It looks like the later number is a plastic roller, not the solid one like on earlier models. That's what my deck seems to have. Is either still available? Don't the rollers just slide on the shaft and are held in place by a cotter pin, right? So the only thing that could keep them from turning would be a corroded shaft, right? If not that then what? Still trying to get this one ready for mowing, if we can get enough rain for the grass to grow.

I had the opposite problem-rollers to loose. Instead of buying the plastic rollers (on my landlord 2110), I got a bigger size rod and put the rollers back on. They work great.

Randy, It sounds like the shaft has rusted inside the rollers. When steel rusts, it actually expands as the rust crystals grow. I would say that you need to remove the shaft and then drive the rollers off the shaft. After the shaft is bare, then clean the rust off the shaft and lubricate it liberally. Put the rollers back on and you should be in business. If these are the type of rollers that have the white plastic bushings, you may need to replace some of these bushings because you may tear some of them up while trying to remove the rollers from the shaft.

And you'll probably have to replace the shaft if you want the deck to cut the highest possible. The combination of worn shaft (thinner) and worn rollers (larger diameter hole) leads to a lower sitting deck. It will still cut well, just not be raised as high as original. The idea of a new larger shaft is a good, solves both problems at once and you don't need to buy new rollers. Should even get a slightly higher cut with the larger shaft.

I ordered a set of new rollers today. The ones I had had been slid enough before I got it that there were flat spots on them. Basically unsaveable. I suspect the rust on the shaft did just as Rod said. Thank's. I really want to try this 7112.

Last night I finally got to removing the rollers. Unbelievable how tight they were. Of the 7 rollers, only 2 would turn. I had to cut the others off. Then the shaft underneath was so corroded, that even the good ones wouldn't slide over it. Tried cleaning the shaft with 50 grit sandpaper, but wasn't working well. Finally ended up having to use an angle grinder to carefully clean off the corrosion, then more sanding... Would have taken a picture but didn't have the camera at home. At least now the new rollers should go on OK, although I probably should have just bought another roller shaft, too:(

Scott, In this case, Randy bought the tractor this way. I lube the shafts on my mowers whenever I take them apart. I feel that any lubrication is better than none. Others may feel differently.

As far as the worn roller bar goes, I rolled the bar over on one of my 60" Sunstar decks and it is now back up to proper hight. I cut the weld off the suport arm, turned it 180 deg. on the bar, and welded it back on. Works great.Whish I had taken some pictures of it but I was in a hurry and didn't even think of it.

Well My new rollers came, and in hopes of cutting grass with this newest addition, I installed them, hung the mower under the tractor, put the belt the previous ower had given me on the PTO, went 20 feet and the PTO belt ran off, jammed between the PTO pulley and the cone clutch, and broke. Even better, the force of whatever happened, slid the rear idler into the front idle, which bent. It took quite some time to get the jammed up belt out of the cone clutch assembly. It's always something....Now I have to get a new idler and belt. Little chance of finding either locally. Oh well at least I had the 712 to cut the grass with.

The saft was broken on my 48" deck and the rollers were so worn (the hole in the middle)that I had to buy new rollers. I welded in a piece of pipe on each support and drilled and tapped for set screws. Now I can remove and replace the shaft and rollers in about five minutes of less. New rollers were 6.95 at my local Simplicity dealer. New 5/8 shaft was 8 or 9 at the local machine shop.

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
