GREASING SCHEDULE & LOCATION
P.T.O. SHAFTS
Your TDR-30 mower is equipped with reduced maintenance drive shafts . This means that greasing of the shafts must be done only every 100 hours of use, or 8 to 10 days of use. This applies to the main input, intermediate and deck shafts supplied with this mower. These shafts are also equipped with the EASY LOCK GUARD
SYSTEM.
BLADE SPINDLE GREASING
This TDR-30 mower is equipped with fully sealed roller bearings that require no regular maintenance. A predetermined amount of grease has been placed in both the top and bottom bearings in order to provide adequate lubrication throughout the life of the bearing.

PRO LIFT-N-TURN™ SYSTEM MAINTENANCE
As with any mechanical system, the Pro Lift-N-Turn™ system needs to be used and maintained properly. With only a few moving parts, this is a simple task.
In a safe level location, fully lower the decks to the ground, shut the tractor engine off, and set the parking brake.
With the lock rope released, all three latch plates should lay flat against the wing frames.
Check each of the three latch plates and make sure they do not bind when the lock release rope is pulled or released.
Ensure that the latch plate, cables and springs are in good condition.
Check to see if the center lock swivel is free to rotate without binding and returns to a neutral position so that the cables have slack
Each latch plate should lay flat against the wing frame when released. Ensure the center lock swivel is free to rotate. when the latch plates are lying flat against the wing frame.
If any binding or damage is found, repair the issue before using the Pro Lift-N-Turn™ system.
It is advisable to instruct all Operators to check the operation of the Pro Lift-N-Turn™ system prior to the start of each shift. Operators should be advised that upon arriving at the work site and lowering the decks, the Operator should ensure that each latch plate is in the fully lowered (flat) position before starting to mow.

GEAR BOX OIL LEVELS
IMPORTANT! DO NOT OVERFILL! MOWER MUST BE LEVEL WHEN
CHECKING GEAR BOX OIL LEVEL
DECK GEAR BOXES
Gear boxes all have an oil level plug located on the side of the gear box. Oil should reach the bottom of this hole. If oil level is low, add oil through top plug hole of casing until oil just starts to flow out of side oil level hole. Replace and tighten plugs.
Use 80W90-gear oil or equivalent.
Filler Plug
Level Plug
MAIN GEAR BOX
The main gear box has a combination filler plug and dip stick. Remove the plug, dry off the dip stick and replace to check oil level. It must touch the oil in the gear box. Add oil as required.
Use 80W90 gear oil or equivalent.
Replace and tighten the plug.

BLADE SERVICING
Be sure safety locks are in place when working on decks in the raised position. The tractor hydraulic system could fail, causing decks to fall and crush anything under them.
Do not handle mower blades with bare hands. Careless or improper handling may result in serious injury.
Inspect blades before each use to determine that they are mounted tightly and are in good condition. Replace any blade that is bent, excessively nicked, worn or has any other damage. Small nicks can be ground out when sharpening.
Only original equipment blades should be used when replacing worn out mower blades. They are made of special steel alloys and subjected to rigid heat-treat and inspection requirements. Substitute blades may not meet these rigid specifications and MAY BE DANGEROUS.
BLADE REMOVAL AND INSTALLATION
Two, 1/2 x 1 3/4” grade 5 bolts with locks washers and nuts hold blade to blade spindle support bar. When changing blades, be sure that these fasteners are in good condition so they will not come loose during operation.
BLADE SHARPENING
IMPORTANT
- When sharpening blades be sure to balance them. Unbalanced blades will cause excessive vibration, which can damage blade spindle bearings.
Vibration may also cause structural cracks in spindle housing.
Follow original sharpening pattern as shown. Sharpen blade to a razor edge.
Protect hands when sharpening. Do not sharpen backside of blade.
41
SPINDLE SERVICE
Spindles are equipped with two roller ball bearings. Adjustment is set by tightening the 1” left hand nut to 60 ft-lbs. torque for proper setting.
Periodically inspect blade spindles by grasping blade, and moving from side to side. If any free play is noted, replace or repair.
SPINDLE ASSEMBLY REMOVAL
Remove blade from spindle.
Remove belt shield. Loosen 4 bolts that hold gear box to mount. Loosen 1/2 x 3
1/2” tap bolts and slide gear box toward front until belt is easy to remove.
Remove belt.
Remove 4 bolts attaching spindle assembly to mower frame and remove as a unit, since pulley will come out through the hole in the deck.
SPINDLE ASSEMBLY INSTALLATION
Reverse above procedure. Be sure spindle mounting area of deck is clean of any foreign material before attaching spindle assembly.
SPINDLE REPAIR
Spindle repair requires special skills and tools. If your shop is not properly equipped or your mechanics are not properly trained in this type of repair, you may be time and money ahead to use a new spindle assembly.
Remove pulley from spindle assembly. Place assembly in press and force spindle down through housing. Once pressed apart, replace bearings, as removal will have damaged bearings internally.
42
SPINDLE REASSEMBLY
Only use a press that has the ram and bed 100% square to each other. If bearings are not square in housing, bearings will wear out prematurely. Press on outer race when inserting into hub and press on inner race when installing on spindle.
If bearings are being changed, be sure to check bearing spacer for wear.
If wear is noticed, insert new spacer.
This is critical because if spacer is short by only .010”, the top bearing will start to bind and will result in premature failure.
Bearing will be pressed into the blade side of the hub first, orientation does not matter. Next, set spindle on press bed, install dirt shield and shim first (as per diagram) set hub, bearing end down, onto spindle. You must use a tube (Note: both ends must be square) which will slide over spindle and press on inner race of bearing, until seated against shim.
Insert bearing spacer tube with hole end up. Set remaining bearing on to spindle, orientation does not matter.
Press on inner race (this bearing will be a loose fit in the hub so it will seat itself properly).
When all parts have been installed on spindle, torque left hand nut to 60 ft-lbs. and then tighten set screws in pulley. The assembly is now ready for installation into the mower deck.
43
“V” BELT ADJUSTMENT
Each mower deck is equipped with 2 spindle drive belts, each with a dedicated draw-type screw tensioner. To adjust belt tension, first remove cover from the side of the deck to be tensioned. Loosen jam nut on tensioner screw and loosen bolt fastening the idler pulley (do not remove). Adjust belt tension the belt using the threaded bolt (see below for specs). Tighten the nut on the pulley and the locknut on the adjuster bolt.
Ensure belts are properly aligned in the correct groove when replacement is required.
“V” BELT TENSION
Proper belt tensioning is a fundamental factor in the successful V-belt operation.
Lack of tension will cause slippage, and too much tension will cause excessive belt stretch as well as damage to the drive components, such as bearings and shafts.
Therefore, to assure proper belt tension, the following procedure is recommended.
CHECKING BELT TENSION
At the mid-point of the span, apply a deflection force with a spring scale in the direction perpendicular to the span until the belt is deflected the 3/8”. The recommended force to deflect the belt is a minimum of 4.9 lbs. to a maximum of
7.3 lbs.
The first 24 to 48 hours of operation is the belt “run in” period. To ensure satisfactory belt performance, belt tension should be checked during this time period.
44
HYDRAULICS
The hydraulic system on your Progressive mower is a simple cylinder system used to raise and lower the cutting decks into position. Each cylinder contains a small diameter restrictor orifice, which is located on the rod end to slow the speed of travel.
Restrictor Orifice
When reconnecting the quick disconnects to the tractor, be sure that both ends are clean. Dirt in the hydraulic system can block the orifice in the line throttle valve or even score the cylinder tubes.
Hydraulic fluid escaping under pressure has enough force to penetrate the skin. See a doctor at once if injured by escaping fluid. During your daily inspection repair all leaks before they create a major problem. Relieve all pressure before working on, or disconnecting the line in the hydraulic system.
If crimp-on hose ends are ever changed, be sure they are compatible with the hose, to provide the proper crimping pressure.
