5.2.2 Skid Steer Universal Quick Attach
Plate
Mounting a backhoe on a skid steer requires the Universal Quick
Attach Plate (1) plus a machine-specific Tieback kit (2). The
backhoe bolts directly to the quick attach plate. The kit includes
flat face couplers.
Skid steer loaders require a tieback kit to properly and safely
distribute the stress produced by a backhoe attachment.
The two main reasons for a skid steer tieback kit are:
1.
Avoid inadvertent movement of skid steer controls while an
operator is on the backhoe.
2.
Reduce pressure spikes in hydraulic lines preventing
damage to the hydraulic system.

If you intend on using this backhoe on a different model skid
steer, a different Tieback kit is required.
Three-point Hitch Mount
In some cases, a Wallenstein backhoe can be mounted on a
3-point hitch with one of the following kits:
PT300 Three-point hitch CAT I
— Suitable for light duty digging
only. For out-of-production tractors equipped with a CAT I three-
point hitch for which no sub frame is available.
PT322 Three-point hitch CAT II
—For tractors with engine
power above 75 hp (56 kW) or equipped with a CAT II three-
point hitch that do not require a subframe.
NOTE:
The GE605 backhoe is not designed or equipped to
be used with a 3-point hitch.
PTO-driven Pump Kits
Tractors without rear hydraulics available for implements require
a PTO-driven pump kit. The tractor must have a 1-3/8", 6-spline
PTO shaft to fit the pump drive coupler. Shaft adapters cannot
be used, and the tractor cannot operate at any speed other than
540 rpm.
It is not recommended that tractors with a variable speed PTO
be used with the backhoe. Operating at speeds higher than
540 rpm can over speed the pump and cause early failures.
