Deck Manual

[wingrider 21]

I'm trying to figure out which mower decks they put on the 876 tractors, I have 2 of these and they both have different decks on them. One has a square rear discharge, and the other is the more round corner style rear discharge. I believe they are both 36". I'm trying to get part numbers and also figure out how to adjust them for a better cut. Will probably rebuild both soon if I can figure out what I have for sure.

Thanks wingrider

RL-366

RL-367

RM-366

Those are showing up as 1966 36" RD Decks. Others more knowing than I will chime in.

Certain decks built as early as 1961 (RM-3661) will work on an 876, as will a few later models - as long as the deck is made for a tractor with a 2.5" engine pulley and the foot-operated PTO. The shell can either be the fabricated rectangular version or the newer one-piece stamped version - depending on the year of manufacture.

The decks that would have normally been sold with an 8hp or less 1966 model (except Lawn Rangers) could have been the RM-326 (translation: Rotary Mower / 32" cutting width / 1966) and the RM-366. The 32" decks don't cooperate well with the tractors with the 8.50" rear tires - especially the hydro models with the increased track width - because of the location of the gauge wheels.

There was also an RM-425 deck sold in 1965 that was designed to work on the 1055 and 1075 models, but a few of them found their way on to 8hp tractors. This deck was a 42" WOC three blade, side discharge model with a nightmare of a drive belt design. WH dealers were constantly having to work on these decks. They were supposedly instructed to offer the customers a new 36" two blade deck in exchange for the problematic RM-425.

The 1966 to 1969 gear-drive two-blade decks are almost identical and are the stamped versions.

(Potential model numbers are RM-366/367/5-2361/5-2362)

This would be the older style:

As long as you have all of the corresponding mounting pieces, either style will work.

The RL decks were made for the Long frame tractors (1056/1257/R-10/C-12/E-12, etc) and can be converted for use on the "little" tractors by switching the #6908 3 groove pulley to one like pictured on the first deck shown above. You would still need to have the correct mounting plates and the foot operated PTO pieces though.

Thanks TT that is just what I was looking for.
