Well, I picked this up last year just prior to moving into a new home and the onset of winter.

It had no PTO foot pedal and the deck needed rebuilt.

So I tackled my other toy first, its a wheel horse C161,

Anyway, I finally got the deck all back together and mowed with it yesterday. Love the striping.

Promised the wife I would try and sell one of my toys so I listed it on another site at premium price:) Not really wanting to get rid of it, but to follow through on my commitment to the wife at least by the letter of the law.

I do have a question.

This runs well. Has a leak that I suspect is the Hydro.

I will eventually tear it down and locate/stop the leak.

However while this tractor has a pretty high top speed it does not seem to have a lot of grunt when it comes to pulling power. The techy seems more than adequate under load with the mower.

Not sure how to quantify it's lack of pulling power but it would not pull a small stump that was out of the ground to the ravine I wanted to dispose of it into. My C-161 pulled it along the top of the ground with almost no effort. Of course its a 16hp vs the 12.

Am I expecting too much from the old girl?

Anyway, If I can get more grunt effort out of her, I will start amassing the implements of destruction such as a tiller etc.

A couple pics. Tractor is original. Deck has new bearings and repainted.

Had a heck of a time finding the blades and finally got them from Jack's Small Engines on line. Getting the D slotted type was a challenge. It would be nice if this spun the blades a bit faster and mulched the clippings a bit. Seems that it shears the grass and it looks a little un kept afterwards. It would be worse but the striping affect makes it look groomed.

Mine has no trouble powering the tiller. It works good and very smooth. Noel

Welcome to GTTalk glad to have another MF12 owner. When I was working mine it had tremendous grunt. If your leaking your definitely not getting the power you should. I would tear it down & rebuild to fix. I have mine completely apart. You have a very nice complete tractor in great shape.

Welcome to GTT :wave:

Good looking machine you have there. Are you running the engine at

full throttle, when you are testing the machines strengths? The hydra units

need to be powered at full speed to work properly.

That is a very nice looking tractor there, I know I love my Masseys of this vintage.

I would examine the drive belt and pulleys between the engine and the transmission. Make sure that the parking brake mechanism is releasing and allowing the clutch pulley full range of motion to put tension on the belt. Also make sure the tension pulley moves smoothly and that the spring mechanism isn't binding somewhere.

I used to have a terrible time with my 12 hydro because I'd forget to take the parking brake off. So the brake would be binding, the tensioning pulley would not hold, but I could still zip around as long as I was on level ground. But it wouldn't pull the hills.

After reading the other comments I remember my brake wasn't releasing all the way when I first got mine. The belt was slipping & like mentioned OK on flat ground but struggled on hills. Once I got that fixed there was no stopping it.

Wow, Thanks for all the replies. A lot of support for these old Masseys. I am glad you mentioned the drive belt as one possible culprit. I release the brake and it appears to release but I will also check to assure its functioning fully as it should. But I have suspected the Drive belt as needing replaced and the tension adjusted. It is the only belt on the machine I have not replaced with new belt. Simply have not yet gotten to it yet. It mows well and summers are short here, winters long. I will tear her down if she remains in the small herd and potentially change out seals and stuff on the Hydro. Glad to hear that she is likely a lot more stout than has been experienced thus far. Weird how I think of my tractors in the feminine gender.......kinda like a ship.
