The Hydraulic lift assembly's are sort of hard to come by as there seems to be a growing demand for them and as soon one is listed for sale someone grabs it.
Your best bet is to keep watching Craigslist and ebay.
Patience is the key in finding one. I finally found one after waiting a few years for the right deal to come along.
We would love to see some pictures of your Bolens !!!!
(We love pictures here )
Believe it or not, I have yet to get my 1000 . The restoration on it is nearing completion and I expect to get it within the next few weeks. I CANT wait!!!!! I have had an 850 in the past . I lost custody of it in a divorce It has her dads tractor(great shape for a late 60's vintage). My Dad had a G 14 when I was a kid so I am not a newcomer to the Bolens family.
In the mean-time, I have a Hy-Lo Jeep pump that has its own resevoir. If it can lift a plow- it can lift a 33" tiller. It also has a v-belt pulley. Not sure if the pump is omni-directional. I hope so!!! As long as I dont have to permanently modify this tractor, I will install it until an original replacement comes along. I am VERY pationate about keeping this '65 as original and as un-altered as I can. I have the resourses to fabricate any brackets and plates to install it as long as the tractor has the room to allow this to happen.
