Troy bult junior has new tines , runs to fast...

what do you mean - are you sure this is a husqvarna or a troy built tiller?

any type of gear oil will work for this. I know some gardners that use tranny fluid for heat

The older models do not have an actual model number but only a name to distinguish the size. Early production models include the Horse, Pony and Junior. You must find the location of the serial number tag to order parts that will fit your particular rototiller for seamless replacement of parts. Hope this will help

double check to make sure you have the new tines in the right direction. also you could try to raise your machine, as the new tines are digging better it might not have to be as low as you had to go with your old ones.

Some Troy Bilt Tillers were designed with a manual "free-wheel". If yours is a Tuffy (and maybe a Junior), you have to pull pins out of the wheels to move the tiller without starting it. The larger tillers, Pony's and Horses, had a lever to shift to release the wheels.

on my pony the disc came off when i removed all of my tine shafts. then i pulled the old seals out an drove the new ones in

Check the Troybuilt website for specific info on your tiller.

The tines sometimes get frozen to the shaft. You might try penatrating oil and use a heat gun or hair dryer to heat to loosen.
Also tap wiht a hammer around shaft.

Hi it sounds like you are trying too till the soil with the tiller in the fast position and probably too deep for your first pass. Really the fast position is for transporting the tiller from the field. Try putting the tiller in slow which would be the down position. Turn the throttle all the way foward, engage the tines and push your depth rod on the back down to where it is only going into the soil about four inches or even less depending on the hardnes of the soil. Even though a Troy is the best Tiller made it will try to run away with you when your trying to hog the soil all at once. Your depth setting is very important and people seem to forget the importance of adjusting it. Try these things, and remember to alway's start your tilling in the slow full throttle position. Lowering your depth a little at a time. Till you find the appropriete feed for your speed.

they should point inwards and towards the rear of the machine
