Bolens QT16

It's a Hydrostatic Bolens QT16 (1666-01) that has always been stored inside and maintained regularly. It's only had one owner. The engine was replaced the winter of 1988 with a 16hp Onan twin. The engine was professionally upgraded to an electronic ignition during the winter of 2000. A brand new starter was just installed. The engine runs strong as can be and burns no oil. A brand new drive shaft was just installed. The rear end has a very minor leak (may leave a small drip over a period of two weeks). That tractor is ran a minimum of once a week and given time to warm up properly (15 minutes or so)if it's not going to be used. It comes with a pto driven 48" mower deck (needs new belt and possibly a pulley for the inside of the deck), 33"(?) rear tiller, and 54" snow blade. This tractor is ready to work! Has never had a problem starting. Tires are in good condition. The rear tires are original and the front tires are about 10 years old. No cracks, plenty of tread. The hydrostatic rear end was professionally rebuilt approximately 10 year ago.

The only problems with this setup is the few parts that the mower deck needs and cosmetic blemishes from normal use. No major rust (just a few knicks and scrapes that rusted over time). All lights (front and rear) work as well. Tractor does not have hood decals.

Just looking for an idea of how much this setup may be worth should I want to sell it. I didn't know how much I may want to ask for it.

Thanks to anyone who comments.
