I Have a Twisted PTO Shaft On a Woods Rotary Cutter what should I do now ?

[Poopdeck Pappy]

The FIRST thing I would do is replace that shear bolt with a proper one. Somebody probably used a Grade 8 bolt in it.

Just be glad the PTO shaft twisted instead of the PTO inside your tractor taking a big dump. The cost of splitting your tractor in half and fixing that would make a PTO shaft look downright cheap.

Hi guys,
Thanks so much for the responses. The Deutz is air cooled . You are right the tractor is way too much for this five foot rotary cutter. The tractor itself measures 7 feet wide.

I will only be cutting a very small area . I will be very careful until I find the right size rotary cutter .

How do I make sure that I get the right size shaft? Any particular PTO shafts that are a better buys?

If anyone can post a link to one that would fit I would greatly appreciate it.

Thank you

PTO assemblies are rated by "series" or "classes" you probably could use a series 5.

The following chart gives you the industry standard for PTO driveline horepower ratings. Please keep in mind these are rated horsepower at the PTO, not engine horsepower. Many times the difference between engine horsepower and PTO horsepower can vary as much as 10%. These values give the maximum recommended horsepower that can be transferred through the drivelive from the tractor to the implement.

Series Rating @ 540rpm Rating @ 1000rpm
1 16 24
2 21 32
3 30 47
4 35 54
5 47 72
6 62 98
7 74 114
8 91 145
9 141 225

chart doesn't carry across correctly but Horsepower Rating and Length

Yep, replace the shaft...
Could have been worse though...although PTO drive shafts aren't cheap, they're a lot cheaper then the other components (gear box, tractor PTO) that could have been damaged.

Hi folks,

We have a bit of a problem. Someone used a bolt that wasn't made to shear . The end result is that the whole shaft arm on our 5 foot rotary cutter twisted horribly .

What is the best way to fix this ? What should I do ?

Thank you so much !

That looks almost identical to my 5 foot Woods M5.

If it is you shouold be able to get the bent part from your Woods dealer. You need item 4 from the image below taken from my manual.

If you have a different model than the M5, you can get a manual from the Woods website here
Rotary Cutters

If you don't see your model listed (mine wasn't) you can ask them with their manual request form and they will email you a copy.
