Rotary Cutter how can I remove cutter assembly?

   / how can I remove cutter assembly? #11  
I made a puller.

take A stout piece of steel, perhaps quarter inch L channel. Cut a piece an inch or so longer then the rotor and cut (torch) or drill holes in the ends to match the blade bolt holes in the rotor. Cut or drill a center hole.

Place a bolt with a head sized to fit inside the center hole on the rotor, but big enough the cover most of the end of the splined spindle.

(I am making some assumptions here as to the rotor and spindle construct. My mowers are JDs which are all built about the same)

Bolt everything up with the center bolt of the "puller" pressing on the center of the spindle, (but not on the rotor), and pulling on the ends of the rotor with stout nuts, bolts washers. "Even" things all up, side to side and then take turns torquing down on each end bolt, while whacking the center bolt with a BFH.

Be careful to stand aside while doing this (I suspend my mower from a chain fall so I can get easy access) as with enough pressure on the puller, the whole rotor and puller will "pop" off the spindle with plenty of force.

The other method I have used with success is taking a heavy pipe 5 feet or so long, that is small enough to fit inside the bolt access holes in the top of the deck. with the center bolt out and the blades off, deck on the ground, drop that pipe through the access hole hitting the ends of the rotor alternatively, HARD, several times.

This has worked for me, especially on mowers with long rotors.
good luck.

I used 2 short pieces of chain with round loops on them, put the loops on the top of blade nuts. Loosened nut on blade carrier part of the way, hooked the chains together and set a 20 ton hydraulic on the chain, as it started up I slid a flat piece of metal between jack and nut.Got back out of the way and kept jacking. It popped loose and slid down against the nut.

that was gonna be my next sugestion.. hyd puller.. :)
