Toro Belt Replacement

I have a Toro HMR 1600, model #55620 Ser # 900000 and up. I have never had to replace the belts that go to the twin peerless transmissions, but I do now. If I try to drop the clutch, (four bolts) all that lowers is the belt tightener assembly and that does not free up the double pulley that is fastened to the crankshaft and drives the transmissions. If I remove the big bolt in the bottom of the clutch (in the center of the pulley that drives the deck) nothing is going to drop without putting a puller on it. How and what do I have to get out of the way to replace the two belts?

Why won't anything drop without putting a puller on it? It's not pressed on, it just slips on. Take the center bolt out, drop the PTO clutch, and then the transmission pulley will drop so you can change the belt.

Toro Belt Replacement

Probably because it has not been off that shaft since it was built. It was in mint condition when I bought it used, and I never had to remove it. So now it wont just drop without a little help anyway. I am going to soak it in PB Blaster, and nudge it just a bit with a puller (very little torque)
Thanks for the reply!

Ok. I've had a few of them stick too. Usually they come off with a little gentle persuasion. Hopefully yours will too.

HMR-1600 Inquiry

WML13, do you still have this mower? I found one in fairly good condition for sale and was considering buying it. My dad had a commercial mowing business in Florida in the 90's, and had four of these HMR-1600s with 52" decks. He had great luck with them. Just wondering if you feel they are a decent mower, that would do me good service on my one acre rural lot.

Hmr 1600

I still have the HMR 1600 (did my first valve job on it last winter) I mow about 4 acres with it, and I am jealous because I only have a 44 inch deck. I would buy a 52" deck if one came in range in a heartbeat. The belts and transmissions can be a challenge, and keep a close eye on the transmission bolts and belt guide adjustments!!!! I would definitely keep those mowers, unless you want to ship one to me.....
