 Topic: 78 Hay Rake
Posted: 13 Jul 2017 at 8:36pm |
Looking for opinions on an AC 78 hay rake. Currently I have a JD 660 with dolly wheel which I am quite used to. First question is what is the difference in using one without a dolly wheel? My late grandpa thought they bottomed out more in uneven ground. Secondly in general will it perform the same as the JD in general? Does it wind it more or less, harder to make a nice corner?

I like a dolly wheel rake better. You can turn shorter without worrying about getting the rake in your back wheels. I think you can make a better corner with one. Also the handy thing about a dolly wheel rake is you can push it around by hand if you need too. The draw back is they are hard to back, just like a four wheel wagon.

78s are a decent rake. The bushings and linkage in the clutch go bad and it will not stay in gear. You will need to rebuild the clutch is all if that happens. Many were also 4 bar rakes but they have the holes to make it a 5 bar. I might have a spare bar to sell yet. My dad made a dolly wheel for ours, made it much easier to use. I could get some pictures of it if you want. Thanks Jim

I've heard the dolly wheels help with following uneven ground. I rake with a NH super 55 without a dolly and it does good enough for me

If a 78 is belt drive keep your Deere. Dad had a few different belt drive rakes and was never impressed. A 660 is a good rake. We have two 640's which are the same but older. We added the fifth bar to ours and run three teeth side by side instead of two. Tom

The 78G is a great rake. Been using one for the past 17 years. I had to replace the driven pulley 2 years ago and last year rebuild the drive clutch and a few teeth. Below is video of the complete process of making hay. Just skip ahead in the video until you get to the raking. Making Hay
