I picked up a bolens two weeks ago traded my 1981 cb750 for it. Its got a 20hp kohler i want to say its a HT20? cant find any tags on it. but i notice its leaking hydro fluid and when i pulled the dip stick half of it was gone so i dont know how much is in it and with it being hydrostatic i dont want to wreck it. if i could get some pics/measurements of the dipstick that would be great and also what type of fluid is recommended
