As Ejl said (while I was still typing
) using the deck lift cylinder as an angling cylinder is not feasable as it has the 4" long slotted float end welded on it plus it only has a 2.25" stroke where the factory cylinder has a 5" stroke per what
@Joelk told me awhile back.
I thought about this last night and I came up with the cheapest solution while using the factory deck lift valve in the factory position.
The deck lift cylinder hoses have male -6 ORB fittings on them. Buy adapter fittings from -6 ORB female to 1/4" NPT female. Then off the shelf 1/4" NPT hoses can be used and hooked to the factory hoses eliminating the need to mess with the proprietary Cub ends in the spool valve. Basically hooking the deck lift hoses to 1/4" NPT ended hoses.
Run those forward to an off the shelf 1.5" bore x 4" stroke cylinder with a retracted length of 10" or less.. The ends are where you need to check to see what will fit. My plow is buried in my wellhouse. I'm hoping
@Joelk will chime in here as he has set up plenty of these and has more CC 3000 tractors than anyone else on here.
Sorry. I didn't realize that the deck lift cylinder had such a short stroke. The implement lift cylinders that I have dealt with were 2" bore x 4" stroke.
There are two benefits that can be derived with a blade that can be angled. One is obvious, snow can be directed off to the side to reduce or eliminate windrows on the opposite side. The second is less obvious, the end of the blade can be used to jack the tractor backwards or pull it forward in order to get the tractor out of trouble..
Information needed, but not supplied, to set up for an adequate hydraulic angle cylinder:
- Width of blade
- Hydraulic pressure available
- Maximum angle L/R desired.
Shorter stroke cylinders can be used for angling a blade, provided that the mounting pin holes are placed in the correct locations with some effort for precision.
Force available at the ends of the blade depends on which end of the blade, maximum angular displacement of the blade, whether pushing that end forward or pulling it back, and on which side of the plow the cylinder is mounted.
The problem is to find the right combination of bore, stroke, and pressure that can assist getting the tractor out of trouble without bending the blade. For a comparative reference, and assuming that the 2.25" stroke deck lift cylinder has a 2" bore, the force available at the end of a 48" blade that can be angled +/-30° is:
- 2 x 2.25 cylinder @ 500 psi = 141 lb
- 1.5 x 4 cylinder @ 750 psi = .. 192 lb
- 1x4" cylinder @1000 psi = ..... 113 lb.
Note: two different stroke lengths, three different bore sizes, and three different pressures. The relevant leverage ratios have been applied. The 1 x 4 cylinder is inadequate, and the 2 x 2.25 cylinder will be quote fast changing angles.
The actual force will be slightly higher or substantially lower depending on which end of the blade is being used and which direction the force is applied (pushing or pulling).
For the extension hoses, my personal choice would be custom made with -6 JIC 37° female swivels to reduce the cost of fittings (2 required) needed to convert to NPT (4 required). Off the shelf hoses tend to be either too short or too long for some applications..
