AHRM48 mower deck

Post by Timj »

Took the chance before I put the AHRM48 deck on for mowing season to swap out the hydraulic motor with the one from my new to me AHSB48 snow caster. This will allow me to test the motor from the caster and also see if it performs better than the motor that was in the deck.
The current motor is getting tired. It doesn't perform like it once did. These hydraulic motors (C36963)are no longer available. They were proprietary and somewhat unique, making finding a replacement tough.
This will give me a little more time to explore finding a replacement or rebuilding.

Got the deck put back together and mounted on the 4118 this afternoon, so I took it out and mowed some grass. :48: Could have waited a few days but I could see where I cut and it will get the neighbors going to get theirs cut. :rofl:

The new hydraulic motor is definitely better than the old one. It doesn't stall out when climbing the hill. :thumbsup:

Hopefully can get a few hundred hours out of this motor. Going to still pursue finding a suitable replacement.

What is the life span of these hydraulic deck motors?

I don't know if there is any good answer. My old one probably has 8-900 hours on it. I have 1220hrs total on tractor. It still works but not as good as it should. I've read of failed ones with only 300 hours.
Ingersoll used a few different manufacturers of these motors, Webster, Ultra, Barnes. I don't know if there is any variation of life to brand.

I have a HRM48H which is for a 3pt. I got a excellent deal on it but it has been setting in a building since I purchased it. It needed a case drain so when I was plumbing up the hydraulic oil filter I added a connection for it. I believe the hydraulic motor is probably similar to the AHRM48 from what I see in the manual. Everything seemed to be there even the belt but I have no idea what condition the motor is in. This is the next shop project tractor related.

I believe they were the same motor. Ingersoll just changed the pulley size for the AH 3pt model to compensate for the higher hydraulic flow of the AH tractors and not over speed the mower.
Let us know as your project progresses.

I have heard that a zero turn mowers with 2000 hours on drive motors are nearing end of life.

This sad Ingersoll has 850 hours on it. It is going to take a lot of time and parts to get it back to drivable. It will be hard to justify putting the time and energy into the repairs if the deck is not serviceable.

Right now the energy needs to be applied to the 646 backhoe.

Spike, I truly understand your thoughts, unfortunately I don't think you'll be able to know the condition of the deck motor without running it on the tractor. If you get it done and your motor is tired, you won't like mowing up your hill.

You could hook it up to one of your other tractors to make sure it turns and doesn't leak oil, but your flow won't be high enough to know for sure. Finding another All Hydraulic owner near by probably slim chance.

Putting that poor tractor back together for just a non "mower" may not have many plusses for you. Might give your Roper blower a boost in Hydraulic performance? Power steering.

I've been trying to figure out a reasonable replacement, but it hasn't been easy. There has been a lot of threads on these motors on other forums, but no answers for a replacement for the NLA OEM. Buying used attachments to get a good motor is an expensive gamble. There's been a used ahrm48 deck for sale on marketplace for a while for $900. :O

I think you have some time to figure out your path while you finish the 646.
