From 350 t0 550 would be good price has to be PTO model if year model guessing right the serial number tell year made. If save any money on buy go by harbor freight buy that 6 1/2 horsepower engine Greyhound engine and put in closet for later. Keep tiller rest your life. I make all pricings lower at pickup point not on phone.

I think I paid $500 for mine. Perhaps a bit high since I knew I would need to work on the carb, but it was from a friend so everyone needs to be happy. If timing is not an issue, you might try looking at auctions where auction time could be traded for a likely great deal. Remember, these are tanks and not likely useful for cultivating but only clear areas.

Check the tines for wear. If they are pointed at the ends, they are worn out. New tines are about $100 and the ends have about a 1" flat. For you use, I would recommend the hardened tines. Also, grab the tine and there should be little to no movement left and right. Check the vertical shafts on which the motor moves up and down for excessive play. They should be oiled and will have some play.

The PTO came out around 1983.

Be sure to check the trans and rear oil levels. If you buy it, I have the proper instructions on checking the levels.

They are easily maneuverable despite their size and the PTO allows safe travel to the site.

For you use, I would recommend the hardened tines.

Have to disagree, yess they last 2x as long but are 2x the price too! these heavier tines also put more stress on the tiller gear box and increase its failure rate. I have been an owner since 1988 and now have two horse tillers. I used the hardened tines a few times but have stayed with the standard ones. I buy a new set each year. Just remember thes machines eat dirt for a living

If you can't afford to buy a new one, that is a decent price.

The serial number is 340455 - around when would that put it being made?

Sorry it took awhile to post back but the seller finally got an email back to me - I guess she had an offer the night she posted the add, though when they showed up a week later they wanted to pay for it on a monthly installment plan.

You need watchout buying this tiller its 1978 year model its miss late 80's earily 90's by mile.

Thanks for the heads-up, I'll steer clear unless the price drops significantly.
