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.

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
