By the way, have you checked what a MMM will cost? Pretty hefty not counting the $500 for the Mid PTO. You're probably looking at $2,000 to $3,000 from JD new IF they can get it for the 870. I was told THAT was discontinued too as a Kit and would have to be ordered as a mower and then all the completion parts.

Have you considered a 3 point Finish Mower? For $800 to $1200 you don't even need the Mid PTO.

I got lucky. I found a MMM on eBay and got it for $475.

By the way, the $500 for the Mid PTO Kit was not that bad when you take a look at what is in the box. It's some major parts.

The 870 manual is not very clear on this but you have to match the wheels and tires for the gear ratio of the two differentials IF your tractor is equipped with MFWD. There is a table that shows this. It's clearer if you look in the 80 loader manual.

It's a bad idea to try and mount R1 or R4 tires on the rims designed for your R3 Turf tires IF you have MFWD.

Deere specifies in the manual which rim/tire combinations are correct for the MFWD 870. The R1/R4 rims are two-piece rims and your R3 Turf tires have one-piece rims.

If you want to switch between one type of tire and another AND have MFWD, you are going to need two sets of rims.

ALSO you can't mix front and rear tire types with MFWD either.

I got lucky when I wanted to have a set of R1s to go with my R3s and found a dealer who had a set of mounted R1s with hardly any use. They cost me $1,000 which is almost what a new set of rims would have cost from Deere ($800 plus shipping and tax)!!!

I was going to look at Yanmar and other Japanese mfrs to see if their was a chance they would fit and I could buy their wheels cheaper, but the dealer came along with exactly what I needed and I didn't check the other routes.

For MFWD 870, you need 7-14 1-piece rims in the front and 12.4-24 2-piece rims in the rear. Then you need rubber, tubes, and mounting. New, you're looking at close to $2,000.

Amazing, I know.
