Well i Just got off a 1/2 hour phone call about a Cab (i have been on the hunt for a cab for my bolens Tube frame) he said he had a Cozy cab of a ht20 ... so i asked about the tractors he has He said he has over 70 tractors and 30 some odd bolens tractors i was telling about OB Hdt1000 and i asked it the grill was different he said the grill is mesh and it has a 3 cylinder liquid cooled engine and he said its based of a Ht23 So i think there is a 3rd hdt1000 !!! but this one is in Canada ! I had a nice chat about bolens and tractors .. he said he has a ht20 with a cozy cab for 1500 No motor .. but i plan to make a trip out there some time .. SOON ! and he has 4 loaders .. many large frames and a 540 pto .. he is also trying to buy a back hoe ..
