Need help with Howard Rotovator.

I have a Howard Rotovator attached to an IH 350 utility tractor rated at 40HP. The problem is that when using the rotovator it seems to push the tractor excessively. I can put the tractor in Neutral and it pushes me faster than my low gear.

I'm trying to ID the tiller to get information on any adjustments. I understand from other posts that their is a clutch that might need adjusting.

The tiller is approx 62" overal width and the tines are 52" cutting width. I also replaced all the tines because the dealer couldn't identify the origional part number (they were marked "ES".

If someone can help identify or help me with any of these problems I would greatly appreciate it.
Thanks

Nothing wrong with the old Howard. When you are tilling the tines are rotating the same direction as you tires, so in contact with the ground it will push your tractor. We always just put ours in a low gear and lift up at the turn row. We dont make a habit of turning off the PTO at every turn because it is hard on PTO clutches. Just lift it enough to clear the ground but not high enough to bind the PTO.

You have some real agressive cutters on there. Sounds like it is working normally. The 'problem' is that these things are pretty agressive, you just have to learn to operate safely.

As others say, if you have a TA it will freewheel your tractor, you need to be using a standard gear.

A slip clutch is a real good idea for other things (protecting the tiller & the tractor driveline from breaking), but will not change the way the tiller operates.

Lift the quick hitch up/ put the pto out of gear at the end of rounds.

your right Paul. I tried it again tonight and it does push the tractor. Since I have ipto I can't stop it with the clutch so I have to turn the Pto after every end row.

It is working normally , I just don't like to nmot have full control of the tractor I guess.

Thanks

I don't know much about the old Howards like you have, but the only clutch i've ever seen in any Howard, is a "drive line" slip clutch, and from your pictures i don't see one. No matter, it has nothing to do with the problem your describeing.

I think another poster had the right answer, you tilling with the TA back, and then the tractor free wheels, so the tiller pushes the tractor.

I'm afraid you probably have the wrong tractor for what your trying to do.

You did not say if your tractor has a TA or not. If it does and you are running with the lever back (TA engaged) then the tiller can push you forward. With the TA forward the tractor should engine brake. I'm guessing you're running with the TA back to reduce the forward speed for tilling.

NEVER EVER use a rotovator with the tractor in neutral. There was a guy over here who had a very lucky escape when, as he approached the headland he depressed the clutch pedal on his tractor ( live PTO)and the rotovator pushed the whole unit into the ditch. For that reason, if you are using a MF tractor fitted with multi-power,it is advisable to flick the multi-power lever into 'high' otherwise you have no engine braking.

I don't usually run the tractor in neutral. I was just commenting that it pushed the tractor in neutral faster than first gear. Anyway when tilling in first gear the only way to stop is to disengage the PTO. I wondering if there is a clutch adjustment or something to address the problem. I also forgot to link a picture for help in identification of the tillers model number.

Simple.....Don't use it with the tractor in nuetral. Use your lowest gear. Some tractors aren't geared low enough for tiller use. I'm not too familiar with your IH's gearing, so I can't comment on that. I have a Howard Rotovator too. It's 80"'s wide. It'll push my 4440 if I put it in nuetral. We're talking an 18000 lb, 130 hp tractor. John
