MID-MOWER LIFT SYSTEM FOR 1 FAMILY TRACTORS
MID-MOWER LIFT SYSTEM
The forward lift link is installed on the deck. It is spring loaded, allowing the link to connect automatically to front hangers (installed on tractor). The PTO drive-shaft design allows the shaft to automatically adjust as the female end of the PTO coupler engages with the male end of the gearbox coupler. The male end coupler has tapered guides to ensure engagement of both ends. Mower decks are equipped with a heavy-duty, double-sided locking latch to ensure rigidity and reliability.

MID-MOWER LIFT SYSTEM OPTIONS
STANDARD MECHANICAL MOWER LIFT
The standard mechanical mower lift system moves the mower in conjunction with the rear implement and is controlled using the rockshaft lever.

OPTIONAL HYDRAULIC MOWER LIFT
The optional hydraulic mower lift system allows the mower to be raised and lowered independently of the rear implements. It uses the dual selective control valve (SCV) (loader joystick) to lift the mower deck.

OPTIONAL INDEPENDENT HYDRAULIC MOWER LIFT
The optional independent hydraulic lift system allows the mower to be raised and lowered independently of the rear and front implements. It operates using the third-function button on the loader SCV joystick and gives the operator full control of the mower deck in up and down directions. This feature allows for quick height changes on the go.

NOTE: This option requires third-function SCV to be installed on the tractor.

MID-MOWER LIFT SYSTEM FOR 2025R TRACTOR

The male end coupler has tapered guides to ensure engagement of both ends.

It operates using the third-function button on the loader SCV joystick and gives the operator full control of the mower deck in up and down directions. This feature allows for quick height changes on the go.

NOTE: This option requires third function SCV to be installed on the tractor.

COMPATIBLE WITH FRONT/REAR IMPLEMENTS
54D and 60D High-Capacity AutoConnect deck is compatible with rear 3-point hitch attachments, backhoes, and loaders. The operator can keep these extra implements attached while mowing. 1 Series and 2025R tractors are equipped with a dual mid-SCV as standard equipment. The mid-mower hydraulic lift can use the dual SCV (loader joystick), or third SCV (optional), to lift the mower deck, giving maximum flexibility.

MID-POWER TAKE-OFF (PTO) DRIVEN
Mowers are driven by the tractor's mid PTO, providing the following advantages:
Rear PTO remains free to operate rear-mounted implements
Shaft drive - no belts used to drive the mower
Faster and easier deck installation than other drive mechanisms

NOTE: To use the mid PTO for other front-mounted attachments, the operator needs to remove the quick-connect drive shaft and rear lift link. Several pins must be removed to allow removing the rear mower mounting linkage from the tractor. No tools are needed.

MOWER HEIGHT ADJUSTMENT
The height-of-cut (HOC) adjustment is located on the tractor and can easily be adjusted with the turn of the knob. To install/remove mower deck, the HOC adjustment knob must be set in the install position.

SERVICE AND DURABILITY
These mowers are designed with many serviceability and durability features. Some of these features are:
Drive over ramps can be easily removed via bolts for belt service
Blade spindles and mower drive shaft are greaseable to increase bearing life
Front lip and trim side of deck are reinforced for added strength
Plastic chute guard
