Buying Advice YM155D just bought

[California]

There will be a certain ratio of front to rear tire revolutions per mile. On any 4x4, a change of tire sizes has to maintain this ratio. I've read that the front should lead by up to 5% and shouldn't be pushed by the back tires.

Now - a new complication: I've seen in some Yanmar parts manuals that they had different gear ratios in the differentials for R-1, turf, etc OEM tires. So I think you can't just buy the alternate type of tire that was also offered that year if that alternate tire spec came with a different gearset.

I would research this thoroughly before buying different tires.

Yes. I thought you were aware but just making sure.

hmmmm.. this puts a new spin on it. Let me get the exact number of the tractor model year etc, and so we can go from there.

thats a nice set up as-is, try the belly mower and see what you think before making wholesales changes to it. As other have stated its very capable in its current work attire, great find, I am from sangerville and there are some finds if you are patient and know what to look for, Thanks for sharing !!!!!

Well I will try it this weekend. The grass in the field is up about 6" and so maybe I will just give it a shot and see what happens. I can start with the deck up high and go from there. Will let you all know.

 

[Beauly]

Well I have read lots, but the debate continues it seems on what to do with the fronts.

Any suggestions? The front turf tires presently on the tractor are 6-12. So what size to go with if switching to Ag tires?

 

[Beauly]

I guess this constitutes me doing research.

 

[grainger12002]

my 336d is on turfs, they work better than I thought they would, did you try the 4wd on your 155 ?

 

[Beauly]

Well yes, I did try the 4WD in that when I drove the tractor around the dealership parking lot, I stopped, and shifted the 4WD lever and then drove around again, so I assume that it is working when engaged. But will have to get on a little hill or left up a wheel etc to make sure that everything is spinning.

I would sell that rig, as is, pocket about $1,000 and buy what I need.. The tires and mower alone are worth $1500.

Per the book the 155d the tires should be front 5/12 and rear 6/12 with optional front 6/12 and rear both at 8/16's. The difference in gears is before serial 5100 and 5101. The difference is after 5101, front tread 29.3 to old 28.in, cooling capacity .8 to .7, and the travel speed faster, pto speed 540 and 770@ 2540 (old ) 540 and 800., starter 1.2kw to 1.0 kw.
