What you have there looks to be a Gilson Twin 18 GT. The model # would be 53054. Contact http://www.toro.com/...es/default.aspx for more info. I tried using their Manual search on their website, but it wanted nothing to do with that model #. I think the best option would be to contact Customer Service directly. Congratulations on the new (to you) machine, and held og lykke!
I went to the site & scanned their lists. Closest I can find is model 53084.
Unfortunately, no version of that model has a manual online at toro
Thank you for all your help. I appreciate it very much. I will contact the customer service at www.toro.com
Ok, here is an update of the manual questions. I wrote to the Toro Customer Service and asked for an Owner's manual and a Part List manual for a Gilson model 53054 and I also added some pictures. They answered back that they could not help me without a serial number. I don't have the serial number. There is no label anywhere. I think is is gone at the restoration with the sandblasting.
I was surfing in the Yahoo groups and there I saw some pictures of a Gilson excactly like mine and I also could see the model number and the serial number. I "borrowed" the serial number from the picture and wrote Toro again.
This time they answered that they were able to find the operators manual and parts manual, but I have to order the manuals at the local distributor LeLy Turfcare DK A/S.
Operators manual # 210895
Part manual # 210899
I called the distributor and they ordered the manuals for me. They didn't even know that Toro had something to do with the Gilson tractors.
Today I got a letter from the distributor an inside there was the operators and parts manual for my tractor.
Good service from both The Toro Company and the danish distributor Lely Turfcare DK A/S.
